NPR has a great interview with two executives from respected non-profit research institutes IGI (International Gemological Institute) and GIA (Gemological Institute of America). Both IGI and GIA grade Ada's diamonds on the exact same 4 'C's as mined diamonds. There are two quotes from the article that I'd like to comment on:
International Gemological Institute (IGI) Executive Director, David Weinstein:
"I deal with diamonds all day long, for three decades," says Weinstein. "To me, diamonds aren't anything spectacular. It's hard to get me to say, Wow!" But lately he has been impressed by certain diamonds — those created in the lab. Under a bright light, he points out how colorless they are, and how, to the naked eye, they're indistinguishable from diamonds that took millions of years to form deep within the Earth.
Weinstein, an expert who likely has over 50,000 hours of hands on time with diamonds over his 30+ year career, is impressed with the quality of diamonds cultured by humans, especially the very high quality color.
His praise for our diamonds makes perfect sense to me, as diamonds cultured in the pristine conditions of laboratory are objectively superior to dirt diamonds dug out of the Earth. Our diamonds have superior purity, superior crystal structure, and very rarely have any foreign material and significant defects that are common in the vast majority of dirt diamonds.
There's a reason that only laboratory grown diamonds are used for surgical knives, water purification, quantum computing, extreme-pressure research, high-end speakers, and many other cutting edge applications: Lab-grown diamonds are a cut above Earth-extracted diamonds.
Gemological Institute of America (GIA) Chief Laboratory and Research Officer, Tom Moses:
GIA doesn't favor one over the other [Lab-grown vs Earth-extracted]. "That's not our job," says Moses, "to determine what the right kind of diamond is for an individual." He says they just want to make sure that everyone's clear on exactly what they're buying, "so that the marketplace — and mainly the public — can make an informed choice."
I strongly concur with Moses. It is very important for customers to know the origin of their diamonds. Ada Diamonds proudly only sells lab-grown diamonds, and we believe that there needs to be 4 'D's to go along with the 4 'C's: Disclosure, Documentation, Differentiation, and Detection.
Ada Diamonds applauds the efforts of GIA, De Beers, and other companies in the diamond industry to develop tools to determine the origin of every diamond ranging from 0.01 carats to 100 carats, and looks forward to working with these tools to ensure that 100% of Ada's diamonds are cultured by humans, not dug out of the Earth.
