Sapphire is a gemstone composed of the mineral corundum. Sapphires are the second hardest substance on earth, second only to diamonds. The name “Sapphire” is derived from a Greek word that means, “Blue Stone.” Although most recognizable in rich, velvety blue, sapphires come in a variety of colors (except red, this is a Ruby.) Due to this gemstone’s inherent beauty, remarkable hardness and a wonderful variety of colors, sapphires are an extremely attractive and ideal gemstone. Sapphire is the birthstone for September and also the gemstone for the 5th and 45th wedding anniversaries.
