Besides blue sapphire and ruby, the corundum family also includes so-called “fancy sapphires”. They come in violet, green, yellow, orange, pink, purple and intermediate hues. Some stones exhibit the phenomenon known as colour change, most often going from blue in daylight or fluorescent lighting to purple under incandescent light. Sapphires can even be grey, black or brown.
