Highly saturated medium or medium dark blue tones are best, blue sapphires which are too dark or too light are worth considerably less.Color zoning is responsible for certain Sapphires having lighter and darker colors in different parts of a crystal. Some Sapphire gemstones may even be multicolored such as purple and blue. Sapphire is a tough and durable gem, and the only natural gemstone harder than Sapphire is Diamond.
