Loose Moissanite Oval Faceted Brilliant Cut 9x11mm stones wholesale from China Suppliers & Manufacturer PICTURES VIDEO  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 has 18% greater luster than a...

(Transparent Series) (The rough is produced by another rough manufacturer) Page 01 Page 02 Page 03   What is Hardened Glass Gemstone?A: Glass is an amorphous form of silica (with various percentages of additives) that has been used as a gemstone for millennia. 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.

SPINEL COLOR CHART What's Synthetic Spinel? Although not as widely used today as #Synthetic Corundum#, #synthetic Spinel# is still one of the most common man-made gem materials, particularly blue synthetic Spinel. It appears frequently in class rings and costume jewelry. Blue, green and other colors of synthetic Spinel are mostly manufactured using the inexpensive flame-fusion method by which the Spinel develops around an elongated boule. These flame-fusion Spinels can be distinguished from natural Spinels by a slightly elevated refractive index due to a chemical variation involving higher aluminum content. Blue synthetic Spinelsof the flame-fusion type are typically colored only by cobalt. No iron is added, and therefore they are diamagnetic, another property that distinguishes blue flame-fusion Spinels from blue natural Spinels. When viewed under the Chelsea filter and also under long wave UV light, the light blue and medium blue gems pictured below left and center show a pale pink reaction due to low cobalt content, while the dark blue gem on the right appears bright red due to much higher cobalt content. None of thesynthetic Spinelsshown below contain enough cobalt to cause magnetic attraction. Blue Spinel gemstonesmanufactured by the slower and more costly flux-grown method have a vivid blue color due to high cobalt content. They are generally small in size, faceted from small synthetic crystals that are shaped like natural octahedral Spinel crystals, as opposed to the large rounded boule shapes of flame-fusion Spinels. Because the major chemistry is the same as natural Spinel, the refractive index range is also the same. While the common flame-fusion synthetic blue Spinels are almost always diamagnetic, flux-grown blue Spinels are weakly magnetic due to their higher cobalt content. This is the only gem material of any kind that we have found that shows magnetic attraction entirely as a result of cobalt....
