Moissanite is one of the hardest gemstones on earth, and in the gemstone world, second only to diamonds in durability. It is much harder than stones such as sapphires, emeralds or rubies and an excellent option for daily wear.
Moissanite is naturally occurring silicon carbide and its various crystalline polymorphs. It has the chemical formula SiC and is a rare mineral, discovered by the French chemist Henri Moissan in 1893. Mineral moissanite was discovered by Henri Moissan while examining rock samples from a meteor crater located in Canon Diablo, Arizona, in 1893. At first, he mistakenly identified the crystals as diamonds, but in 1904 he identified the crystals as silicon carbide. Silicon carbide is useful for commercial and industrial applications due to its hardness, optical properties and thermal conductivity. Moissanite, in its natural form, remains very rare. It has been discovered only in a few rocks, from upper mantle rock to meteorites.
Look for the words “Platinum," “PLAT," or “PT” followed or preceded by the numbers “950” or “999." These numbers refer to the purity of the platinum, with “999” as the most pure. For example, an authentic piece of platinum jewelry might have a stamp reading “PLAT999." “Pt” followed by the level of purity- i. e. Pt900 or Pt950. The number 900 denotes 90% pure platinum, and 950 denotes 95% pure platinum. There is no real difference in quality between 90% and 95% platinum.
