Sapphires, a variety of the mineral corundum (next to Ruby) is formed deep underground and brought to the surface by aluminum rich igneous rocks, or in metamorphosed rocks. Magma cools as it passes through these rocks, crystallization within the rock creating Sapphires. The slower the cooling process, the larger the crystals are. Sapphire can be found in blue, black, green, purple, orange, and yellow or colorless. Blue Sapphires are the most well known and have been associated with royalty for centuries. Traditionally, Sapphire has been known as a symbol of power and strength, but also of kindness and wise judgment. It is thought to bring serenity and to help focus the mind.
