What's the Blue Sapphire Color Stone?

Blue sapphire belongs to the mineral species corundum. It can be a pure blue but ranges from greenish blue to violetish blue. The name “sapphire” can also apply to any corundum that’s not red and doesn’t qualify as ruby, another corundum variety.

Sapphire is the September birthstone and for the 5th and 45th anniversary gemstone gifts. For specific birthstone information, September birthstone, Sapphire comes in all colors except red! It may be colorless, a deep blue, green, golden yellow, pink, reddish-orang, and violet. The most valuable color of sapphire is referred to as "corn-flower blue;" black, grey, or green overtones to this vivid blue will reduce overall value. Blue sapphire is not as expensive as diamond, emerald, and ruby, with the exception of the rare variety called Padparadscha, an orange-pink stone, and some Pink stones.

The most common Corundum colors are Blue Sapphire and Ruby color stones, but we can also supply White Sapphire, Orange Sapphire, Yellow Sapphire and Alexandrites in all shapes and sizes.

We have quite a collection of Blue Sapphire Color Loose gemstones such as popular Round Brilliant Cut,Princess Cut,Emerald Cut,Cushion Cut and also unique heart, Oval,Octagon,Marquise, Pear,Star Cuts and Much More... Special Shape and styles are available.

What is Corundum and What are its Basic Qualities?
A: Corundum is an aluminum oxide that commonly forms hexagonal barrel-shaped prisms that taper at both ends or as thin tabular hexagonal plates. It has a hardness of 9 on the Mohs scale, making it one of the most durable commercial gemstones. It has no dominant cleavage and fractures in a conchoidal manner. A high density of ~4.0 g/cm3 (most silicate minerals are ~2.6 g/cm3) results in corundum occurring in secondary placer deposits and recoverable by panning methods, similar to how you would recover placer gold.

Corundum comes in all colours of the rainbow but is most commonly found as opaque crystals with dull colours. Red corundum is called ruby, blue corundum is called sapphire, and all other colours are called fancy sapphires. Some varieties of corundum will fluoresce under short wave and long wave UV light if there is enough chromium in the crystal structure but little iron, which tends to quench any emitted energy.
