What is Sapphire?

[steem]

Hello

Sapphire is a precious stone or gem that is a form of corundum, a hard mineral of aluminum oxide. Sapphire is prized for its translucent beauty. It is the focal point of many pieces of fine jewelry. Sapphires can be set in pendants, rings, earrings, brooches and tiaras.

Sapphire is usually thought of as a deep blue gem. However, sapphire is found in many different shades of blue, as well as many other colors. Sapphires that are any color other than blue are called fancy sapphires. Fancy sapphires can be orange, yellow, green, pink, or purple. Red sapphires are called rubies.
