Moissanite, zirconia, etc. are also artificial stones, but they are different types of stones. Lab-grown diamonds are 100% diamonds. It takes over a billion years of pressure and high temperatures for natural diamonds to form. Lab-grown diamonds, on the other hand, are created by advanced scientific technology that significantly streamlines this process, replicating the same geological environment in a lab. They have the same structure as diamonds, and even professional gemologists cannot distinguish them. Only with the help of specialized equipment can the difference from natural diamonds be identified. We handle everything from diamond procurement to bezel production and diamond setting in-house, so we offer high quality at a low price. ●Material Stainless steel CVD Lab-Grown Diamond VVS class Approx. 1.45CT, engraved on the back 41mm Chronograph model ●Included Items Special tool Glass case Our gem identification certificate (card with tester results image)
