Blue is one of the most popular colors as far as gemstones are concerned. The topaz, turquoise, tanzanite, lapis lazuli and aquamarine are all blue stones while the zircon although not a natural blue, it turns blue when treated with heat. The Sapphire, as the September birthstone, is the most sought after of the blue stones and has a variety of blue hues varying from light blue to a very dark greenish-blue to a violet-blue. The sapphire is a gem of high value and many royals have used sapphires as part of their adornments over the centuries.
Sapphire is from the mineral group corundum and is composed of aluminum oxide. The blue colors are a result of the titanium and iron substitutions that occur in the aluminum oxide crystal lattice. Asterisms or point stars, namely 3-point or 6-point stars, are present in some sapphires and when sapphires are cut into cabochons, they are cut to display the effect of these stars to maximum effect. What makes the sapphire such a splendid gemstone is the high amounts of refraction that is found within the gemstones. The more intense the blue color, the more desirable they become. The most valuable of the blue colors is the Kashmir Sapphire or the Cornflower blue Sapphire.
