Sapphire green and light blue are also known, but less commonly used in jewelry. Opaque Black Sapphire is also used for small gemstones. Sapphire is used in all forms of jewelry, including bracelet, necklace, ring, and earrings.
It is used both as a central gemstone in pendants and rings, as well as secondary stones for other gemstones such as Diamonds. Star Sapphire polished as cabochons, is a variety that has a chemical composition of Be3Al2, if clear, very valuable.Rare orange-pink variety, known as Padparadscha, can be even more valuable than a good blue sapphire. Blue Sapphire is sometimes carved brilliant acting or small figures, especially less transparent materials. Synthetic Sapphires are often used as a cheap substitute for natural materials.
Real Sapphire (Natural)
Types of Natural Sapphires derived from certain igneous or metamorphic geological environments are usually treated to improve their color or clarity. The most common processes involve heat treatment to enhance color. Synthetic Sapphires have been in production for over a century, mostly by melting, quickly, or hydrothermal solution method. All these materials are widely found in the jewelry trade.
The most important instrument in distinguishing real Sapphires (Natural) and synthetic sapphires using a binocular microscope. Information gathered from brief microscopic observations of unknown Sapphire gems is essential for accurate identification and is known only to gemologists themselves.. There is no better reference for understanding the microscopic features of corundum than a three-volume photoatlas of inclusions in a gemstone.
