Loose Natural genuine Black sapphire Square shape Step Cut 3x3mm and 5x5mm gemstones 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.

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.
