FAQ

Lab-grown diamonds are chemically, physically, and optically the same as natural diamonds. Both are made of pure carbon arranged in a crystal lattice structure, and both are graded by the same 4Cs: cut, color, clarity, and carat weight.

Lab-grown diamonds are an ethical and eco-friendly option, and for good reason. They avoid conflict sourcing and use far less land and water than mining. While production does require energy, many manufacturers are shifting to renewable sources. For the most sustainable choice, look for brands like Keyzar, which follow carbon-neutral practices.

No, lab-grown diamonds do not get cloudy over time. They have the same chemical structure and durability as natural diamonds, meaning they maintain their brilliance indefinitely. However, just like mined diamonds, they can accumulate dirt, oil, and residue, which may dull their sparkle. Regular cleaning with a gentle jewelry cleaner or mild soap and water keeps them looking as brilliant as the day you bought them.

Yes, lab-grown diamonds are certified by reputable gemological labs like GIA, IGI, and GCAL. These certificates assess the same qualities as natural diamonds—cut, color, clarity, and carat—and clearly state the diamond's lab-grown origin. Certification ensures authenticity, quality, and transparency when buying a lab-grown diamond.

Keyzar made it very easy for me to customize and select the perfect ring for my fiancé. The way my schedule is I knew it’d be tough to actually go out and search for one. Their online shopping tool was great. If you’re hesitant to shop for a ring online, don’t be! I couldn’t be happier!

100% recommend, I was looking around for a couple of months before I found Keyzar. They had the exact style of ring that I was looking for and I loved how I was able to customize the size diamond I was looking for as well. Customer service was fantastic and the ring was made and to my door within a few weeks time.

The website made it very easy to pick out a stone and setting for my ring! I love that I could visually see what it would look like. I was hesitant to buy online instead of seeing things in person. The turn around was pretty quick and the delivery was tracked and needed my signature. I appreciated that. I LOVE my new ring. It is gorgeous and so perfect!
