Sapphire is an extremely versatile gemstone that has many applications beyond gemstones and jewelry and comes in a wide variety of colors and optical properties. Sapphire is used in scientific instruments, windows, wristwatch crystals and special purpose electronics. But it’s most well known for the deep blue color of sky above. With light blues of midday to that of the inky evening sky, sapphire has a color for everyone.
Sapphire is a stone that has many different origins, and many different varieties. From grayish – blue Montana Sapphires to pinks and purples from Madagascar, Sapphire is found on almost every continent. Sapphire has always been one of the Big Three gemstones, and the deepest blues have always been prized and are found in many “crown jewels”. Most recently, Sapphire was the stone of choice for a royal engagement ring. Blue Sapphire is a stone that will not lose its demand anytime soon. But alas, there is no blue, without yellow and orange.
Yellow and orange varieties are definitely the setting sun in the sky that is sapphire. Sparkling with a bright luster that commonly seen in corundum stones, these colors are very representative of the fall colors we start seeing in September. Natural yellow an orange sapphire are not seen in the quantities we see in the Blue and Black variety, but are just as beautiful.
Aside from the wide variety of colors Sapphire comes in, it also displays some very cool optical properties. The most well known is the asterism of a Star Sapphire. These stars are caused by intersecting needle like inclusions reflecting light and giving the illusion of a six-rayed star. Color Change and Color Shift are also found in Sapphires, but are seen less than those with asterism.
September’s birthstone sure packs a wallop and JTV.com has plenty of sapphires in plenty of colors. There is no reason to limit these to those born in September. We’re fine with anyone getting one or two. Or even five. Go crazy…
