Real diamonds. Straight answers.
Don Key is a Los Angeles fine jewelry brand. We make lab-grown diamond stud earrings, pendants and tennis bracelets in solid 14K gold, set by hand on Hill Street in the Downtown LA jewelry district.
Every ready-made piece uses CVD lab-grown diamonds, graded in-house to our VS clarity, F–G color standard. Stones 1 carat and up are IGI certified, with the lab report included. Natural diamonds are available for custom work.
Our founder started brokering on the tables of LA's diamond district at 19, grew up in a family jewelry trade, and was among the first to bring lab-grown diamonds to the US. Our story
Are lab-grown diamonds real diamonds?
Yes. Same carbon crystal, hardness and sparkle as a mined diamond; only the origin is different. Ours are grown by the CVD method and always sold as lab-grown.
Are your diamonds certified?
Every stone 1 carat and up is IGI certified, with its own IGI lab report included in the price. Smaller stones are graded in-house by Don Key, which keeps everyday pieces affordable. Every piece also comes with a Don Key Certificate of Authenticity. How we grade
What does 1.00 TCW mean on studs?
Total carat weight is both earrings together, so a 1.00 TCW pair is two 0.50 carat diamonds. Stud size guide
