Lab-Grown Diamond Engagement Rings on the Rise

2023-11-282023-12-12 by Rylee Kahan

Picking an engagement ring is a daunting task for anyone. There are so many variables involved, such as: What kind of gemstone does your partner like? Though a diamond center stone is the most common choice, some people sometimes choose ruby, emerald, or like Princess Diana, sapphire. What kind of metal should you choose? Yellow, white, or rose gold, or maybe platinum. Should you go big and bold, or subtle and minimalistic? Usually all these questions can be answered by a talk with your partner, but if you don’t want to let on that you’re gearing up to pop the big question, this blog might be a good tool to help you out.

There are plenty of options, so many that it can be overwhelming, but there are ways to get beautiful rings at less cost than you’d expect. Diamonds mined from the Earth are the traditional gem of choice for engagement rings, but modern technology has now brought us the choice of a Laboratory Grown Diamond.

How Are Lab-Grown Diamonds Created?

We’re glad you asked. Lab-grown diamonds are one of the newest and most exciting things in the jewelry world right now. A lab-grown diamond is a diamond created in a laboratory by simulating conditions similar to that of a mined diamond. Scientists start with a diamond “seed” (pure carbon) and, using modern tech, can reproduce the natural situation that grew diamonds, from carbon, in our Earth’s crust nearly 1 billion years ago.

And just like they grew, crystal by crystal in the Earth, they are grown in laboratories but in a much shorter time. As a result, growing is not only less expensive but is ecologically sound and conflict free. To break it down easily, the conditions diamonds are grown in can be simulated in a lab, and thus lab-grown diamonds are made at a fraction of the cost of mined.

Lab-grown diamonds are just as stunning as the mined versions. They have identical chemical, physical, and optical properties as a mined diamond because they are a diamond. Lab-grown stones retain the same brilliant shine and sparkle as a mined diamond but at a much lower cost. What this simply means is that while you are scouring stores for the perfect diamond ring, you might be missing a perfect opportunity to get her the ring of her dreams, all while maintaining your budget.

Picking a Lab-Grown Diamond Engagement Ring

Her ideal diamond is usually one on the bigger size, but that often means significant cost increases. This new option means that she can have a larger diamond which is now comfortably within your budget goal.

For the ladies reading this blog, you might want to show your partner the price difference when it comes to lab-grown versus mined. You just might get the ring (size and quality) you’ve always wanted, and your partner wont’ be upset about the dent it puts in their wallet! That sounds like a win-win situation to us. A lab-grown diamond simply means that beautiful rings are attainable and available to everyone.

If you’re already purchased your diamond ring, but are thinking about getting something bigger, we at Leo Hamel Fine Jewelers will trade up your mined diamond for lab-grown, right here in our store!

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.

Gemstones That Are Rarer Than Diamonds

2023-04-202023-12-09 by Rylee Kahan

Diamonds are by far the most coveted gemstones in the world. And gem quality diamonds are rare compared to the total quantity of rough diamonds that are mined. Especially rare are gem quality diamonds of over one carat in size. This scarcity contributes to their value.

It might surprise you to know that there are several colorful gemstones that are even rarer than diamonds. Because of their rarity, these gemstones are not frequently found in jewelry. For this reason, they’re less well-known than gems like sapphires and emeralds, but certainly not any less beautiful.

Taaffeite

This extremely unusual gemstone was discovered accidentally in 1945 by Austrian geologist, Count Edward Charles Richard Taaffe. While combing through a box of spinel gems, Taaffe noticed there was one that was different from the rest. Because Taaffe was the first to discover taaffeite, the stone was named after him. Taaffeite can occur in colors ranging from deep purple to red, though red is the most uncommon.

Surprisingly, this stone scores an 8 to 8.5 on Moh’s Scale of Hardness, making it unusually durable. Very few taaffeite gemstones have been found since their initial discovery. In fact, the only known deposits are in Sri Lanka, Tanzania, and China. If you’re lucky enough to find one of these dazzling gems, expect to pay about $1,500 to $2,500 per carat.

Tanzanite

Though tanzanite can be purchased rather easily, it is still considered rare because of scarcity. This gemstone is found exclusively in Tanzania, specifically in the foothills of Mount Kilimanjaro. Because this is the only known location where tanzanite can be mined, it is predicted that the world’s supply will be depleted within 20-30 years.

Iconic jeweler Tiffany & Co. famously used tanzanite in their designs, further driving up the demand for these beautiful gems. Tanzanite’s deep violet and blue hues make them comparable to sapphires, and they’re often used as an affordable alternative. However, as supply decreases, tanzanite’s value will likely skyrocket. Presently, you can anticipate one of these stones to cost you roughly $600 to $1,000 per carat.

Black Opal

Opals are a rather common gemstone and can be found in many jewelry stores. However, black opals are a unique exception. Black opals mesmerize with their celestial colors swirled against an ink black backdrop. It’s no wonder they’re considered to be so exquisite! Similar to tanzanite, black opals are found solely in one location – along the Lightning Ridge in New South Wales, Australia. To own one of these captivating gemstones will cost you around $2,300 per carat.

Red Beryl

Red beryl derives its bright red pigment from the trace element manganese. This gemstone is a relative of emerald, aquamarine, and morganite. Red beryl is primarily mined in the Wah-Wah Mountains of Utah, though small deposits have been located in Mexico and New Mexico. Most stones that are mined are not large enough for faceting, though if you’re fortunate enough to find one, it could cost you over $20,000 per carat.

Benitoite

Benitoite is found primarily in San Benito County, California, which is why California adopted the stone as their state gem. Other specimens have been found in Arkansas, Montana, Australia, and Japan, as well as other regions within California. However, the only gem quality stones have been produced exclusively by the San Benito mine.

Benitoite is sometimes referred to as the “blue diamond” for its mesmerizing translucent blue color. Because of its rarity, most gem quality benitoite is sized at a carat or less, though the largest ever found was nearly 16 carats. To get your hands on one of these gems will cost you about $6,500 to $8,500 per carat.

Alexandrite

Deemed the “emerald by day, ruby by night,” alexandrite has unique color-changing properties that make it highly desirable. In lighter environments, alexandrite sparkles a rich blueish green color, while darker settings cause the stone to transition to a vivid magenta or purple tone. This one-of-a-kind gemstone was first discovered in the mountains of Russia in the 1830s.

It was highly coveted by the Russian aristocracy, deriving its name from Czar Alexander. New deposits have recently been unearthed in Brazil, East Africa, and Sri Lanka. Perhaps these new locations will yield enough to help ease prices, but in the meantime, alexandrite can cost as much as $15,000 per carat.

Musgravite

Musgravite was first discovered in the Musgrave Range of Southern Australia. It is from this range that it derives its name, though traces have now been found in Sri Lanka, Madagascar, and more. Musgravite is found in colors ranging from a greenish gray to purple and scores an 8-8.5 on the Moh’s Scale of Hardness. This score makes musgravite ideal for use in jewelry, but unfortunately quantities are too limited. Despite the discovery of new deposits, availability of musgravite is still scarce, in turn making them quite pricey. The cost for one of these rare beauties? Specimens have sold for as much as $35,000 per carat!

Painite

In 2005, painite took the crown as the world’s rarest gemstone according to the Guinness Book of World Records. At the time, there were only 25 known specimens in existence. Today, that number hasn’t increased by much, with the only known source of painite being in Myanmar. This gem can occur in colors ranging from brown to red, and even pink. Painite is pleochroic, meaning that it can appear to change colors when viewed from different angles. So, what does the world’s rarest gemstone cost? If you’re able to locate painite on the market, it may cost you as much as $50,000 to $60,000 a carat.

Grandidierite

Grandidierite was discovered in Madagascar in 1902 by a French minerologist, Alfred Lacroix. He named his treasure after French explorer and naturalist, Alfred Grandidier. Since his initial finding, small samples of grandidierite have been found in Namibia and Sri Lanka, though very few have been gem quality. Grandidierite commonly occurs in a teal blue color and can transmit light due to it being pleochroic. Specimens that are fully transparent are considered the rarest. Forbes ranked this gemstone the third rarest on earth, with prices as high as $20,000 per carat.

Though these gemstone varieties may be hard to come by, there are an abundance of dazzling colored gems that are available for you to enjoy. Here at Leo Hamel Fine Jewelers, some of our new and vintage jewelry features precious gemstones such as emeralds, rubies, sapphires, and everyone’s favorite – diamonds!

Gemstones: San Diego’s Rich History

2022-12-302023-12-09 by Rylee Kahan

Southern California has produced some of the most beautiful gemstones, and San Diego has played a large role in that history. Six years before the 1848 California Gold Rush started, miners in 1842 were pulling museum-quality gems out of the hills of San Diego County.

The Dowager Empress of China was particularly obsessed with pink tourmaline, making this gem especially lucrative. Now famous Tiffany & Co. was the facilitator of the pink tourmaline trade between Southern California and China.

Royalty in China would place an order and a Tiffany gemologist, J.L. Tannenbaum, commissioned miners in Southern California to mine and ship the order. This continued until 1911 when the Empress died. San Diego’s mines sent over 120 tons of gem-quality pink tourmaline in just their last decade.

Topaz is another gem that is a Southern California specialty. John W. Ware was a San Diego jeweler who owned and operated a small mine on Smith Mountain that produced blue topaz. He had marketed the product from his small mine so well that he eventually was importing the gem to meet his demand.

Sempe and Tourmaline Queen are two of San Diego County’s mines where another gemstone, Morganite, was discovered. The gemstone was named by George F. Kunz, another Tiffany & Co. gemologist, after one of Tiffany’s most distinguished customers at the time: J.P. Morgan. While the discovery and rise in popularity of morganite is attributed to Southern California, it’s since been mined from Afghanistan, Brazil, and Madagascar.

Local Gemstones On Display

San Diego structures are still home to some of these local gems. One of the most notable of these displays was Jessop’s Clock in downtown San Diego. The clock was designed by Joseph Jessop (second-generation jeweler with a local mine at Mount Palomar) and finished construction in 1907. It contains 17 gems that were mined from the Jessop Mine including tourmaline, agate, topaz, and jade.

The clock stood outside of J. Jessop and Sons Jewelry Store through two downtown locations. In 1984 it was relocated to Horton Plaza where it was on display until 2019 when the lease agreement at Horton Plaza ended. Since 2019 it’s been kept safely in storage, awaiting a new lease to be signed for its public display.
