Sapphire

The term sapphire refers to multiple colors of the mineral corundum, with the most well known being a dark blue. Sapphires naturally occur in blue, pink, white, and even green tones. Corundum can also be found in shades of red, but is then referred to as Ruby.

Sapphires are very hard gemstones, second only to diamonds. Like rubies, they are mainly found in parts of Asia, Africa, and Australia, but there is also a sapphire mine in Montana.

The word sapphire comes from the greek word sappheiros meaning “blue stone.” Along with diamonds, emeralds, and rubies, sapphires are considered precious stones. Sapphire is the birthstone for September.
