Loose Moissanite Diamond D EF GH and Color Moissanite stones at highest quality Wholesale at factory direct price from China Suppliers & Manufacturer What Is Moissanite? Moissanite was first discovered in trace quantities that were carried to Earth from a spectacular meteorite. Possessing fire, brilliance, and luster far greater than that of a diamond, Moissanite stones sparkles unlike any other gemstone on earth. Composed of carbon and silicon, Moissanite is also one of the hardest and toughest known elements on earth, making it extremely resistant to scratching, chipping and breaking. Its durability and incomparable beauty make it an ideal center stone for an engagement ring or jewelry gift. Moissanite Diamonds come in many fancy shapes and sizes and can be used to create a one of a kind Moissanite Ring or used in other unique Moissanite Jewelry. Moissanite Optical Properties: Moissanite's characteristic sparkle is more than just a show of beauty - it's a testament to the superior science behind the jewel, boasting more fire, brilliance and luster than any gemstone on earth. This is not merely a sales line, but a scientific and quantifiable fact. Moissanite is known for its high refractive index of 2.65, which is notably higher than diamond, sapphire, CZ and other gemstones known to be very brilliant. Brilliance is the flashes of white light exiting the top and sides of a gemstone. The higher the refractive index of a gemstone, the more brilliance the jewel emits. Moissanite's superior refractive index makes Moissanite the most brilliant fine gemstone on earth. Moissanite's fire, the flashes of colored light, is even more impressive, being more than twice that of a diamond. Luster is the amount of light that is reflected back to the observer from the surface of the gemstone. In addition to superior fire and brilliance, Moissanite...

Clear glass for gems is man-made, formed by fusing silica sand with various additives at temperatures of 1000+°C.Natural glasses include obsidian, which is is a rapidly quenched lava, and closer to pure silica glasses, such as libyan desert glass.A unique man-made glass, although not often used in gems for obious reasons, is trinitite, a mildly radioactive glass formed from the fusing of sand by the detonation of the first atomic bomb in 1945.Common glass has poor dispersion and refractive index, however it is very cheap to manufacture and is known in jewellery terms as paste - often backed with metal foils to increase brilliance. Hardened Gemstones is the best stimulant for the CZ Stones, which the colors are beautiful, but are cheap for the Jewelry designs. Contact us for the further information if you have questions.

Understanding the moissanite carat weight: The industry has traditionally measured a diamond's weight in carats (1 carat equaling 200 milligrams). Since moissanite gemstones are only slightly less heavy (lighter) than natural diamonds, the size of a natural diamond and moissanite don't differ. For instance: A 6.50 mm round brilliant natural diamond would have a carat weight of 1.0. A moissanite of the same dimension (6.50mm) would have a carat weight of 0.88. Simply put, the weight of the two stones may be slightly different, but the millimeter size has been cut to stay the same. In order to fit available settings, it's often easier for jewelers to order moissanite by millimeter. The specific gravity of moissanite is 3.21 grams per cubic centimeter, so a 6.50 mm round brilliant moissanite jewel is approximately 0.88 carats. And we usually make all the loose gemstones in mm size, so, please kindly refer to this CT weight MM Chart to fit your jewelry desgins.
