Laboratory Grown Diamonds

The conversation concerning synthetic diamonds continues to spread and evolve and we want our customers to understand our position on laboratory-grown diamonds in 2019.

Synthetic diamonds have been evolving since the 1960’s when General Electric began researching and developing technologies to manufacturer laboratory created diamonds with the same physical and chemical composition of those mined from our earth. They consulted with both the Gemological Institute of America (GIA) and DeBeers on this early research. Diamonds have not just been for adornment in jewelry but highly sought after for precision manufacturing. As the hardest known natural substance and with the highest thermal conductivity of any natural substance, diamonds are used for cutting and polishing as well as in the beauty industry and medical research because of their unique properties. The quality that is used in manufacturing is considerably lower then what we find in jewelry which generally uses the top 5% in terms of quality. Both DeBeers and the GIA have spent decades and millions of dollars continuing their research on the development and growth of synthetics. Until recently it was mostly to be able to identify a synthetic/laboratory-grown diamond versus an earth grown or natural diamond. Having witnessed this research at the GIA research laboratories on several occasions, it’s fascinating; it takes a lot of technical expertise, a tremendous amount of monies, sophisticated machinery and lots of energy use to grow these diamonds.

The manufacturing of synthetic diamonds, which to date are predominantly created in China, requires a tremendous amount of fossil fuels and are in no way environmentally friendly. Yes, they have the same chemical and physical properties as a natural diamond and are cut and polished using the same methods as a natural diamond.  Yes, they are less expensive then earth-grown diamonds, yet they have little to no value in the secondary market and neither have a provenance nor a history. Natural gemstones, on the other hand, have a history, a mythological story and are helping communities in around the world. “Diamonds do Good” ,

Over our history of 120 years, Lux Bond & Green Jewelers has neither promoted synthetics to our customers nor seen the value of synthetics as an alternative for natural gemstones. Synthetic colored stones have been around for well over 100 years, specifically with emeralds, rubies, and sapphires. We have sold synthetic material per customer requests and have presented a few bridge fashion jewelry collections in sterling silver and other non-precious materials as well as gift lines with cubic zirconia. Yet we have never promoted synthetics of any kind as fine jewelry.  With our involvement and knowledge of the jewelry and watch industry, we have fully expected the value of synthetics to rapidly decline in pricing very similar to what has happened to the television set industry. We believe that the prices will continue to decrease until technology, cost and demand become in balance, setting the ultimate lower value. Lux Bond & Green is about the value and the relationships and trust we have with our customers. Selling synthetics today is a gamble and LBG doesn’t want to gamble with our customer's money for short-term profitability.

Lux Bond & Green continues to be involved in our communities and our industry, endorsing and encouraging ethical environmental and social responsibilities and sound business practices. As leading members of the Responsible Jewelry Council, Jewelers of America, American Gem Society, Manufactures Jewelers & Silversmiths Association, Jewelers Vigilance Committee, American Gem Trade Association, Diamonds do Good and others we uphold their code of ethics for our company and staff each day.

We believe in the intrinsic value as well as the emotional and historical value of diamonds and colored gemstones today and the years to come.
