September’s Birthstone: Sapphire gems are most commonly found in a range of blue shades although they can be many colors. Sapphires actually come in almost every color of the rainbow—including pink, peach, orange, yellow, green, teal, and purple. Red sapphires are better known as rubies (both are varieties of the mineral corundum).
The Gemological Institute of America is an authority of the diamond and gemstone industry and this is what they say about sapphires: Besides blue sapphire and ruby, the corundum family also includes so-called “fancy sapphires.” Corundum can show a phenomenon called asterism, or the star effect. This phenomenon usually appears as a six-ray star pattern across a cabochon-cut stone’s curved surface. The star effect can be seen in ruby or any color of sapphire, and it arises from white light reflecting from numerous tiny, oriented needle-like inclusions.

Besides fancy sapphire and star corundum, there’s another interesting variety: color-change sapphire. These fascinating stones change color under different lighting. Their presence adds a special dimension to the already amazing corundum family of gems.

Both blue and fancy sapphires come from a variety of exotic sources including Madagascar, Tanzania, Sri Lanka, Myanmar, and Australia.
