Moissanite is a rare, naturally occurring mineral also known as silicon carbide, which was first discovered by the Nobel Prize-winning chemist, Dr. Henri Moissan, at the site of a massive meteorite strike in Arizona. This intriguing new stone was named “moissanite” in his honor. Composed of carbon and silicon, the Moissanite is one of the hardest and toughest known elements on earth, making it extremely resistant to scratching, chipping and breaking. Possessing fire, brilliance, and luster that far surpasses even that of a diamond, Moissanite twinkle, and sparkles unlike any gemstone on earth.

Yes, Moissanite is a real gemstone, known for its exceptional sparkle and durability. All our Moissanite stones are rigorously tested and certified. If you would like a GRA certificate, simply contact our team after purchase — we’ll gladly assist you.

Lab-Grown Gemstones are the stunning, ethical and affordable alternative to Earth-Mined Gem, by recreating the earth’s natural process in a controlled lab environment, that are higher quality and more beautiful than most earth-mined equivalents. With a Lab-Grown Gemstone, you get a show stopping centerstone without having to worry about negatively affecting the environment or humanity.

Yes! Just like Lab-Grown Diamonds, our gems are 100% real! We use REAL synthetic Rubies, Sapphires, Emeralds, Alexandrites etc., that are chemically, physically and optically identical to earth-mined gemstones, but the best part is they are up to 90% less!

We offer jewelry in 925 sterling silver, solid gold (10K/14K/18K) and platinum. Sterling silver is elegant and affordable, while solid gold provides enhanced durability and long-term value for everyday wear.
