Loose Synthetic Aquamarine Spinel Aqua Blue Color #106 Elongated Cushion Shape Faceted Cut 12x10mm Gemstones wholesale from China Supplier and manufacturers. Pictures 106# blue color stones usually used as the simulated color of Aquamarine Color Gemstones. What's Synthetic Spinel? A: 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 Spinels of 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 the synthetic Spinels shown below contain enough cobalt to cause magnetic attraction. Comparison of Spinel and Other gemstones: The Popular colors of Spinel Stones: 104#, 105# and 106# are the simulated colors of Aquamarine, 104#Light, 105# Medium and 106# dark. 107# 108# colors are the simulated colors of Topaz Sky blue, 120# is the simulated color of Topaz London Blue. 119# is the simulated color of Topaz Swiss Blue. 112#, 113#,114# are the simulated color of Sapphire blue. 149#(Light) and 152#(Dark) are the simulated color of Tourmaline Green Color stones....

Loose Natural genuine Black sapphire Round shape faceted 1.7mm and 1.5mm meleegemstones Wholesale at factory direct price from China Suppliers and manufacturers. Picture   What Is Black Sapphire? Black sapphire is a nearly opaque stone whose color is so dark that it appears to absorb all light that enters the gemstone. For example, see a black sapphire ring here. Sometimes, this stone also looks very dark blue or gray. Black sapphires come mainly from Australia and are mined in large quantities. This variety of sapphire is very cheap and is considered low grade. An Alternative to Onyx? Because of its color, black sapphire is often confused with Black onyx. Indeed, this stone can successfully act as an onyx substitute. Although both stones look very similar, onyx is actually softer, while sapphire is one of the hardest gemstones (9 out of 10 on the Mohs Scale of Hardness). Because of this similarity, you may consider getting a black sapphire for your ring or pendant if you want a stone that has the color of onyx but is much harder. Is Black Sapphire the Same as Black Star Sapphire? Black star sapphire has a similar sounding name but is actually a different stone. It is a variety of the so-called “star sapphires” – stones that due to their unique crystal structures reflect light in the shape of a star. Black star sapphire is mostly mined in Thailand, West Africa and India. Should You Buy Black Sapphire? When considering black sapphire, you should keep in mind that it is deemed a low-quality stone. The good thing about it is that it’s cheap.If you are looking for a black and opaque gemstone, this is not a bad choice because sapphire is extremely hard.
