The price is affected also of the brightness and cut of the stone as well as the carat weight. Sapphire of the best quality is the one the purity of which is visible to the eye and some inclusions are detected under a microscope. More common sapphires weighing up to 2 carats, but stones from 5 to 10 carats also occur. Usually sapphires reach much larger size than rubies.

Fake and Counterfeited Stones

As a precious stone in great demand the sapphires are often counterfeited. When buying a sapphire you can run into a fake glass, cordierite, tourmaline and other stones.

The fake stone can be distinguished from natural by scratching the surface of the stone. Due to the high hardness of sapphire no marks left at scratching as opposed to fake. There is also a method using different liquids with a certain specific weight to recognize the authenticity of sapphire. Lowering the stone in a liquid sapphire just "drown", a fake on the contrary - will remain on the surface.

These methods have a certain disadvantages: the perceived color can quickly lose its brightness and color when exposed to sunlight or heat. Therefore, you should buy a sapphire from a trustworthy seller providing all necessary information regarding each particular stone.
