Sapphire is one of the classic big three precious gemstones, alongside emerald and ruby. Sapphires come in every color of the rainbow, except for red! Red sapphires are what we call rubies, but both are made of the same mineral, corundum. Traditional blue sapphires are the most highly prized, especially in royal or cornflower tones (the bluer it looks, the better). But pink sapphires are also very popular in recent years. Other colors include yellow, green, orange, and really any other color of the rainbow (except red!). Sapphire is the birthstone for September.
