Sapphire

Sapphire is a corundum gem which makes it harder and enduring than many other gemstones. Sapphires are known for their vivid crystal blue color, but not many people know that this stone is also found in orange, green, purple and yellow colors. The color of this stone depends on different types of minerals present in them. The name sapphire is derived from a Greek word ‘sappheiros’ which means blue. Birthstone for the month of September.
