Sapphire
Apart from the popular blue sapphires - fancy sapphires come in violet, green, yellow, orange, pink, purple and everything in-between. Some stones exhibit the phenomenon known as colour change, most often going from blue in daylight to purple under incandescent light. Sapphires can even be grey, black or brown. Blue Sapphires can be vivid and saturated like they have been lit from within. Sapphire is the birthstone for September, and the gem of the 5th and 45th Wedding Anniversaries.
