Who Founded Tiffany & Co.?

2023-11-172023-12-11 by Rylee Kahan

Tiffany & Co. is one of the most universally recognized fine jewelry brands. Since it was founded in 1837, Tiffany & Co. has produced highly desirable necklaces, engagement rings, earrings, and other kinds of accessories. Collections such as Return to Tiffany®, Tiffany Infinity, and Tiffany Celebration® have earned the company status as an iconic American brand time after time. The distinct Tiffany blue color has become a symbol of fine jewelry, high-end fashion, and sophistication. That did it take to become one of world’s biggest brand names? There is more to the company’s history than meets the eye.

The Early Years of Tiffany & Co.

The premier jewelry store was founded in 1837 by Charles Lewis Tiffany and John F. Young. Originally, it was called Tiffany & Young. In 1853, Charles Tiffany bought out his partners, established sole control of the company, and renamed it as we know it today – Tiffany & Co.

In the beginning Tiffany and Young did not intend on selling jewelry. The store was opened as a “stationary and fancy goods” store with a $1,000 advance from Tiffany’s father. During the 1867 Paris World’s Fair, Tiffany & Co. was awarded the grand prize for silver craftsmanship. This marked the first time and American design house had been so highly honored by foreign peers.

Tiffany has been a valuable asset to America’s history for over 170 years. During the Civil War, Tiffany designed ceremonial swords as well as swords to be used in battle by soldiers. In 1885, Tiffany redesigned the Great Seal of the United States, which is displayed on the back of the dollar bill to this day.

Trademark Collection and Other Accesories & Adornments

Besides brilliantly stunning jewelry, Tiffany is also known for producing a variety of accessories. In the 1960s, Tiffany was commissioned to create the White House China for President Lyndon B. Johnson. Today, Tiffany has an entire line dedicated to accessories consisting of key rings, handbags, sunglasses, writing instruments and more.

One of Tiffany’s signature accessories if the Return to Tiffany® key rings. Introduced in 1969, eack key ring is inscribed with the message, “Please Return to Tiffany & Co., New York”. Each one has a unique registration number so if the key and owner are ever separated, they can be reunited at Tiffany’s Fifth Avenue flagship store. Now, the company has a whole collection devoted towards the iconic phrase, “Please Return to Tiffany & Co.”

Sports Trophies

One of the more surprising details of Tiffany’s history is how involved the brand is in the sporting world. Tiffany has been at the center of American sports since 1860, creating trophies for horse racing, the World Series, the Super Bowl, the Indianapolis 500, and more. The iconic brand also creates championship rings for the NFL, MLB, and USA Basketball.

Since Superbowl I in 1967, Tiffany & Co. has created each Vince Lombardi trophy. The trophy stands just under two feet tall at 22″, weighs over 7 pounds, and is adorned with a regulation-size football. While the first trophy was given to Vince Lombardi in 1967 after the Green Bay Packers victory over the Kansas City Chiefs, the trophy wasn’t the “Vince Lombardi Trophy” until his death in 1970.

Engagement Rings & Other Fine Jewelry

In 1886, Charles Tiffany had an epiphany about how engagement rings should be set. Rather than having an exceptional diamond hidden in a bezel setting, as was the fashion at the time, he decided that the diamond should stand out above the band, maximizing its brilliance. Thus, the creation of the Tiffany engagement ring became the engagement ring as we know it today.

Tiffany & Co. is also highly regarded for their yellow diamonds. Tiffany’s love for these rare and radiant diamonds dates to 1878 when Charles Tiffany purchased the 287.42-carat Tiffany Diamond. The priceless stone, one of the world’s most important diamonds, was cut into a cushion-shape brilliant weighing 128.54 carats and still resides at the trademark New York Tiffany location.

Tiffany’s reputation continued to flourish with the production of the 1961 film Breakfast at Tiffany’s. This was allegedly the first time the store ever opened on a Sunday and allowed filming inside. During production, Tiffany hired 40 security guards to protect all the precious pieces.

How Do Mechanical Watches Differ From Quartz?

2023-11-142024-03-20 by Rylee Kahan

Mechanical watches are wonders of tradition, meticulousness, and craftsmanship. That’s what makes them loved, prized, and coveted. Luxury watch brands, such as Rolex, often grow in value as time goes by. But this is only if you take good care of them. There are a few things that you should be careful about after buying your Rolex in San Diego stores, and we’re listing them here. Feel free to visit us in store to get more first-hand information about the care and maintenance that premium-quality watches require.

Adjusting the Day & Date

In general, adjusting the day and date shouldn’t be done when the watch reads between 9 p.m. and 3 a.m. This time window varies from one manufacturer to another, but the point is that you shouldn’t do this a few hours before or after midnight. Even though the date and date functions do the changeover at midnight, the gears that perform this engage earlier. If you don’t follow your instruction manual when it comes to changing the day and date, these indicators could get misaligned, and some components might get broken.

Screwing Down the Crown

Some professional watches, like diving models, have a crown that must be screwed down. This gives the watch added waterproof capacity. The crown should screw between 1.5 and 3 full turns to only finger-tightness. However, owner sometimes cross-thread the crown in this process or screw it back too tightly. Cross-threading could cause permanent damage, and forcing the crown back could make it almost impossible to unscrew. If you ever feel resistance while doing this, stop, carefully unscrew the crown, and start again.

Underwater Functions

Chronographs are generally water-resistant, to varying degrees. While there are some chronographs that are fully operational even while submerged, you want to check this before you do it. You can refer to the manual or ask the seller/manufacturer. If you are not sure whether you can use the chronograph underwater, better not to risk it. When the pushers are pushed into the case, water may enter, depending on the watch’s structure. Needless to say, this turns into major water damage very quickly.

Magnets

Don’t rest your hand with the watch on large stereo speakers, clock radios, an iPhone, and iPad or Kindle cover, etc. The magnetic fields inside these appliances and objects can magnetize the watch, causing it to run ahead or late. You can check this by placing your watch under a compass and moving it slowly. If the compass needle reacts and moves likewise, you can be sure the watch was magnetized.

November Birthstones: Citrine & Topaz

2023-11-102023-12-09 by Rylee Kahan

November babies are lucky enough to have two beautiful birthstones: topaz and citrine. For centuries, the two gemstones have been confused since they have a similar appearance. However, there are a few distinct differences between the two November birthstones. Citrine, said to be a gift from the sun, ranges in color from lemon yellow to bright orangey brown. It is also said to be the “healing quartz” for its ability to comfort, soothe, and calm. Citrine is one of the most popular and affordable gemstones, making it a great choice for big, bold, statement pieces.

Topaz is also considered to be a soothing stone that can calm tempers and eliminate nightmares. Unlike citrine, topaz has a wider range of colors and is offered in shades of yellow, brown, green, blue, red, and pink. The most popular color of topaz is Imperial Topaz, which features a vibrant orange hue with pink undertones. Both gemstones are durable and are available in a wide range of sizes and shapes. Topaz and citrine’s beautiful colors make exceptional centerpieces for rings, necklaces, earrings, and bracelets. If you’re looking for the perfect birthday gift for the November baby in your life, or maybe just a special holiday present, view some of our favorite November birthstone selections below.

Why Do the 4Cs of a Diamond Matter?

2023-11-072023-12-09 by Rylee Kahan

When it comes to buying an engagement ring, knowing and understanding the “4C’s” of a diamond can certainly come in handy. Considered the universal method of evaluating a diamond, the 4C’s can help both consumers and professionals determine qualities and classifications of a diamond that differentiates it from the rest. Standing for cut, clarity, color, and carat, these four characteristics are used to help measure the quality and determine the value of a diamond.

Cut

The cut of a diamond is the most important factor in determining the beauty and value of a diamond and has the most significant effect on its overall look. When a diamond has an “ideal cut” the light reflected from the diamond is unobstructed and maximizes the brilliance, scintillation, and sparkle of the diamond. Often confused with shape, different types of diamond cuts include round brilliant, princess, pear, old European, marquise and more.

Clarity

Clarity grades are used to describe internal imperfections of a diamond called “inclusions” and external imperfections called “blemishes.” Both blemishes and inclusions can diminish the light as it passes through your diamond and some can even be seen with the naked eye, appearing as dark specks, white feathers, or “cracks” in the stone. The clarity of a diamond is measured on a scale ranging from F (Flawless) to I (Included).

Color

The most valuable white diamonds have no color at all. Most diamonds have some tint of yellow or brown in the body of the stone and generally the more color, the lower the value (fancy-colored diamonds are the exception, such as intense fancy yellow). The color grade of a diamond is based on a scale ranging from colorless (D) to deeply colored diamonds (Z).

Carat

The carat weight of a diamond is often categorized as size, but it’s the weight of the stone. One carat is divided into 100 points (like a dollar is divided into 100 pennies) so a diamond weight half a carat if 50 points, written “0.50ct.” The larger the carat the rarer the diamond, and rarity drives price. An average of 250 tons of ore must be mined to produce a 1 carat gem quality polished diamond.

Certificate

Often referred to as the 5^th C, the diamond certificate is your guarantee that a diamond’s 4C’s have been confirmed by a reputable laboratory. Since anyone can print an invalid certificate and offer their opinion on the grade of a diamond, it’s important that the certificate comes from a well-known independent laboratory. The best independent laboratories are the GIA (Gemological Institute of America) and AGS (American Gem Society).

Buying a diamond engagement ring or any diamond jewelry can be a stressful experience. At Leo Hamel Fine Jewelers, our expert sales associates, will give you all the information you need to make an informed decision and feel confident about your purchase. After 43 years of helping our customers invest in the best quality diamonds, we are experts on the 4C’s!

What is a Troy Ounce?

2023-11-032023-12-09 by Rylee Kahan

One of the main questions that we are often asked by first-time customers looking to sell their valuables is: “What is the process?” That depends entirely on the item itself, its condition, the market price for its material on a given day. However, there is one factor we consider and that’s the item’s weight, especially when it comes to precious metals. This value is based on the actual weight measurement of the materials at hand.

Seems straightforward, right? But did you know that precious materials have their own standard unit of measurement? Chances are when someone refers to the weight of an ounce, they are referring to the avoirdupois ounce used on bathroom scales, kitchen scales, produce scales, etc. Precious metals, however, are measured in troy ounces. The difference between these standards of measurement is minimal – a troy ounce weighs 31.103 grams, while an avoirdupois ounce weighs 38.349 grams. But it’s important to understand that a troy ounce weighs slightly more than the ounce most of us are used to.

History of the Troy Ounce

The term “troy” is assumed to have been adapted from the name of the French market town of Troyes. The merchant fair held there is believed to date back centuries and was known to have grown internationally famous by the 13^th century. As one of the most significant centers of commerce in existence at that time, with merchants attending from various countries, it was necessary to have a standard system of weights and measures that would be understood by all. It’s easy to forget in our modern world that operates on systems of paper and electronic transactions, that once upon a time money was a commodity measured by the weight of real goods.

As the avoirdupois ounce became more popular, the troy ounce was retained for measuring gold, platinum, silver, and even gunpowder to maintain purity standards and common measures across time. Most of the bullion, bars, and coins still in existence today were cast and created in troy ounces, so to convert everything into avoirdupois ounces now would create a bit of a headache. Items would have to be individually converted and recalculated every time or melted down and recast at a different weight entirely. So, the troy ounce lives on, operating in harmony with the common avoirdupois ounce. Do you have gold or silver bars or coins that you want to sell?

How Long is a Rolex Made to Last?

2023-10-312023-12-09 by Rylee Kahan

To say that Rolex watches are not exactly cheap is an understatement. If you do decide to invest in a luxury timepiece, you probably want to know how long it will last.

While they’re definitely made to last, they still need some attention to stay in perfect shape over the years. If you already own one and need to have it serviced or want to know where to repair Rolex watches in San Diego, we have your answer!

With assistance from the knowledgeable in-house watchmakers at Leo Hamel Fine Jewelers, your Rolex watch is certain to last a lifetime. Visit us today!

How Long Will a Rolex Last?

When you think of Rolex, you think of superior quality and impressive durability. While such a reputation is surely a good thing for a brand, it sets the bar high and inevitably begs the question: do Rolex watches live up to their name?

One thing is certain, Rolex has been consistent in producing top-quality timepieces that keep their luster over long time periods. What’s more, the brand continues to perfect and improve their watches year after year, making sure they still look as pristine in half a century as they do immediately after production.

If you own or want to invest in a Rolex, you probably want to know how long it should last. Thanks to the master craftsmanship and exquisite attention to detail that Rolex is known for, it’s safe to say that your timepiece is likely to stay in good shape for generations with proper care and maintenance.

This is evident in the fact that vintage Rolex watches are a watch collector’s favorite. Vintage models like the Rolex Oyster Perpetual Submariner that are still in perfect working condition are quite common. Their appearance may show signs of aging, but with proper service from experienced watchmakers, they’ll look as good as new.

Does Rolex Have A Lifetime Warranty?

While we’ve established that Rolex watches are highly durable, they don’t come with a lifetime warranty. Instead, all watches are covered by an international warranty for a period of 5 years after purchase. The warranty excludes:

Wear-and-tear (straps and non-metal bracelets)
Cases of theft and loss
Damage caused by misuse
Adding or substituting components with non-original parts
Repair or service done by a third-party

Some people may be disappointed with the duration of the Rolex warranty. However, it demonstrates just how confident the brand is in the quality of its products. In many cases, a Rolex timepiece can last a lifetime, especially if it’s serviced regularly. Rolex recommends service every 10 years, but every 5 to 7 years is good for ensuring optimal performance.

Where to Repair Rolex Watches in San Diego?

Rolex watches are undeniably high-quality and durable, but should still be regularly checked. Regular service and maintenance are a must if you want to make sure your watch is always in perfect condition. In the unlikely but not impossible scenario of your Rolex breaking down, you should have seasoned professionals who can fix the issue efficiently and expertly at your beck and call.

Classic & Timeless Jewelry That Will Round Out Your Wardrobe

2023-10-242023-12-09 by Rylee Kahan

There’s no better way to dress up an outfit than with the right accessories. Whether getting dolled up for a night out, a vacation, or even just the office – there are some classic jewelry staples every woman should have in her closet. Just like your favorite little black dress, the right accessory will make you feel confident and elegant. But how do you know which jewelry pieces are a must-have? Not to fear, we’ve compiled a list for you!

Diamond Studs

A simple diamond stud is one of the most versatile jewelry items a woman can own. For a more understated look, pair studs with a casual outfit such as a V-neck tee and jeans. Or wear them with a blouse and heels for something a little dressier. No matter the outfit, diamond studs make a great addition, providing the perfect touch of sparkle.

Long Chain Necklace

Whether you prefer white metals or gold, a long chain necklace should be a piece in every woman’s wardrobe. Long chains can be layered together or worn alone, depending on the look you wish to achieve. Tops with high necklines can be paired with a long chain for an added touch of sophistication.

Cartier Tank Watch

This watch has been worn by the likes of Fred Astaire, Princess Diana, Jacqueline Kennedy, and many others since its release in 1917. Perfect for transitioning from day to evening, this timepiece can be worn with almost anything. Though there are various models of this watch, that which is most frequently photographed on celebrities is the Tank Française.

Hoop Earrings

Hoop earrings come in a variety of shapes, sizes, and styles. If you’re looking for something to really sparkle, opt for diamond hoops for a perfectly polished ensemble. Whether you enjoy a pair of mini hoops for everyday wear, or you’re looking for a statement piece for a night out – hoops are a great option to have in your jewelry box.

Pearls

Pearls are timeless and have been a symbol of elegance and luxury for decades. Pearl accessories are perfect to wear for job interviews, weddings, anniversaries, or any other occasion that requires you to be a little dressier. Invest in a strand of pearls or a pair of sophisticated pearl earrings. They’re sure to enhance any outfit.

Tennis Bracelet

Set with diamonds that encircle your wrist, tennis bracelets are great for adding a touch of bling to your wardrobe. These bracelets are flexible, making them comfortable and easy to wear every day. Because tennis bracelets fit more loosely than other styles, they can be worn casually or formally, depending on the occasion.

Pendant Necklace

Like diamond studs, a pendant necklace is essential for every woman to have in her classic jewelry collection. Nothing is more beautiful than a delicate pendant resting on a fine chain. Whether it’s a monogram, religious symbol, or even a simple shape – pendants come in a variety of styles that can be personalized to your tastes and interests.

Cocktail Ring

Popularized in the 1920’s, cocktail rings are great for spicing up your wardrobe. They usually feature a large gemstone as their centerpiece, to immediately catch the eye. Though not practical for everyday wear, a cocktail ring will surely compliment your favorite dress and heels – any may even be a conversation piece. One thing to remember when choosing a cocktail ring: the flashier, the better!

Chandelier Earrings

Looking for the ideal accessory to wear with an elegant up-do? Then you’ll love a dazzling pair of chandelier earrings. Usually fashioned with gemstones or intricate metal designs, chandelier earrings are sure to make you stand out. Because of the variety of shapes and styles, the right chandelier earring can enhance the shape of your face. For example, those with round faces should opt for a long, slender pair that will elongate the face and make it appear thinner.

Stacking Rings

Stackable rings are one of the best accessories for personalization. There are no limits to how many rings you can wear at one time, nor are there rules about mixing metals. Depending on your outfit, you can easily adjust your ring stack to match by adding or removing items as necessary. The best part? Designing a ring stack gives you an excuse to shop for more one-of-a-kind items to expand your collection!

At Leo Hamel Fine Jewelers, we offer a selection of these jewelry essentials and more! Whether you’re an avid collector, or are just beginning to invest in fine jewelry, there is something for you here at Leo Hamel’s.

A Diamond’s Journey to Fine Jewelry

2023-10-202023-12-09 by Rylee Kahan

Have you ever wondered how diamonds are formed and what the mining process looks like? Diamonds have a long way to go, starting with their formation in the Earth, mining, and cutting to reaching diamond wholesale brokers and jewelry stores in San Diego or elsewhere. Read on to find out how diamonds travel from beneath the ground to your jewelry box.

How Diamonds Are Formed

For a diamond to form in the ground, extreme temperatures and pressure are necessary. More specifically, the temperature has to be between 1700 and 2400 degrees Fahrenheit, while the pressure has to be between 650k and 870k pounds per square inch. This critical environment is necessary not only for diamond formation but also diamond stability. According to geologists, commercial diamond deposits contain diamonds that are formed in the Earth’s mantle, 90-120 miles beneath the Earth’s surface. Once formed, these diamonds are believed to be brought to the surface by deep-source volcanic eruptions. Diamond prospectors are on the lookout for kimberlite and lamproite pipes formed during these eruptions.

Main Diamond Miners and Producers

Originally, the majority of the world’s diamonds came from South Africa, India, Brazil, Angola, Botswana, Namibia, and Congo. Nowadays, the majority of mines are located in Russia and Botswana. The biggest diamond miners of today are De Beers, ALROSA, Rio Tinto Diamonds, Debswana Diamond Company Ltd., and Dominion Diamond Corporation. Around 50% of all diamonds are mined either directly from the ground, the mines or kimberlite and lamproite pipes, while around 48% is mined from riverbanks and other marine environments. Miners have to sift 200-250 tons of Earth on average to mine 1 carat of diamonds.

Sorting the Diamonds

When they are mined, diamonds are far from polished jewelry-grade gemstones; instead, they are still in their crystal form. Before they are sold, they have to be sorted. The majority of diamonds are sorted by DeBeers (around 45%), whereas the rest are sorted in Mumbai, Antwerp, and Johannesburg. There are three categories into which a rough diamond can be sorted.

Gem-Quality Diamonds

Around 20% of mined diamonds are sorted into the gem-quality category. These are composed of at least 99.95% carbon. As the name suggests, they are used for jewelry making. They are valued for their color and clarity, whereas shape is not so relevant at this point.

Industrial-Quality Diamonds

Around 80% of the world’s mined diamonds fall under this category. They are mostly yellow in color as yellow diamonds are the hardest diamonds. Industrial diamonds can be classified either according to their carat weight or the number of points. They are used in the automotive, aviation, and marine industries for making tools for drilling or as abrasives.

Other Diamonds

Diamonds that are not sorted into the gem or industrial categories appear in very small percentages. They are typically crushed and later used as diamond dust for diamonds polishing.

Diamond Cutting and Grading

After they are sorted, gem-quality diamonds are cut into the desired shape. Cut is the most important feature of a diamond, so this process is extremely important. Most diamonds are cut in Belgium, Israel, India, South Africa, Russia, and Canada. The cutting process can last anywhere from a few hours to a few weeks, with some large diamonds event taking years to cut. For example, the Pink Star diamond, the largest Internally Flawless Fancy Vivid pink diamond ever graded by GIA, took two years of cutting and polishing to be honed into the desired oval shape.

Reaching the Consumer

Once the diamonds are cut and polished, they are ready to be sold to the manufacturers, dealers, retailers, or collectors. At this stage, gem-quality diamonds are ready to be set into jewelry. On average, it takes around 5 months for a diamond to reach the consumer after it has been sorted.

Leo Hamel Fine Jewelers offers premier-quality diamond jewelry, most notably exquisite new and vintage diamond engagement rings. Stop by our luxurious showroom on San Diego Avenue and check out our collection of dazzling diamond jewelry!

What Makes Colored Diamond Jewelry So Unique?

2023-10-172023-12-09 by Rylee Kahan

Diamonds come in as many hues and intensities as nature can possibly create. The most common diamond is the white, or colorless, diamond. However, this “white” color ranges from completely colorless to actually showing a light tint throughout the body of the diamond. The light coloring is most commonly shades or yellow, and sometimes shades of brown.

These color distinctions are very subtle and are often indistinguishable to the untrained eye, but they can make a big difference in diamond quality and price. Diamond color is graded on a scale from D to Z, from absolutely no hint of color to a visible tint of color throughout the body of the stone. Diamonds graded from D to F are considered colorless; G to J is considered near colorless; K to M is faint color; N to R is very light color; and S to Z is light color. The less color in the diamond, the whiter the diamond appears.

The further down the scale (from N to Z), the more yellow or brown the diamond appears. Diamonds actually occur in all shades of the rainbow, not just white. Naturally colored diamonds include brown, red, pink, gray, blue, green, violet, purple, orange, yellow, and black. When yellow and brown diamonds are an intensely saturated color, they are referred to as “fancy” colored diamonds and are most valuable.

Colored diamonds are created in the same fashion as colorless diamonds, but more chemistry is involved. When foreign materials other than carbon are present during a diamond’s crystallization process, it alters the chemical development, thus changing the color of the diamond. The result is a beautiful, naturally colored diamond.

How Do Diamonds Get Their Natural Color?

When different trace minerals and elements are trapped during the crystallization process the result is the creation of different hues.

Brown, Red, and Pink Diamonds

While still buried deep within the Earth’s core, intense pressure and heat causes distortions in the crystal lattice during the diamond’s voyage to the surface. This change in the electron structure absorbs green light, which reflects a pinkish hue and produces brown, red, and pink diamonds.

Gray and Blue Diamonds

When boron is present during the chemical process it bonds to the carbon in the crystal structure. This bonding causes the absorption of red, yellow, and green areas of the color spectrum and reflects a bluish/grayish color.

Green Diamonds

Right before a diamond is about to burst through the uppermost layer of the Earth’s crust, it absorbs naturally occurring radiation. This radiation absorbs red and yellow light, which creates a green reflection.

Violet and Purple Diamonds

There are a few different theories about how these diamonds get their color. The cause of color is due to a type of crystal distortion; however, it is also believed the presence of hydrogen is a key factor.

Orange and Yellow Diamonds

Orange and yellow hues are attributed to one specific element – nitrogen. Nitrogen atoms will bond in such a way that blue light is absorbed, producing a yellow reflection. The absorption of both blue and yellow spectrums results in an orange reflection.

Black Diamonds

Contrary to all the above colors, a black diamond’s color is not related to trace elements. Small inclusions of graphite and iron clusters create this color, making the diamond appear opaque.
