Besides blue sapphire and ruby, the corundum family also includes “fancy sapphires.” They come in violet, green, yellow, orange, pink, purple, and intermediate hues. Shown here is the rarest of all, the Padparadscha. Some stones exhibit the phenomenon known as color change, most often going from blue in daylight or fluorescent lighting to purple under incandescent light. Sapphires can even be gray, brown, black, or white.
Most gems are colored by impurities in the crystal. Peridot’s yellow-green is due to the presence of iron. Higher quality stones have an intense color. The best peridot is pure grass green. Most of the stones with the finest color come from Myanmar and Pakistan. Peridot has extremely high double refraction: when you look closely through the gem, you can see two of each pavilion facets.
