To most gemstone enthusiasts, sapphire is considered the most precious and valuable of the blue gemstones. It is a variety of the mineral corundum. Sapphire is very desirable due to its amazing color, hardness, luster, and durability. Sapphire is found in many different colors (red corundum is considered ruby) but when sapphire is referred to without a color prefix, it will generally be blue. “Fancy sapphires” come in violet, green, yellow, orange, pink, purple, and also come in stones that show a combination of different colors. Fancy sapphires create a rainbow of options for people who love the romance and royalty associated with sapphires but who desire something out of the ordinary. Many people associate sapphire with Princess Diana’s amazing engagement ring given to her in 1981, now worn by Princess Kate. Sapphire is a US birthstone for September.


Most blue and fancy sapphires are found in Australia, Cambodia, China, Kenya, Madagascar, Myanmar (Burma), Sri Lanka, Tanzania, United States, and Vietnam.
