Wholesale Natural Gemstone Beads Large Stock with Factory Price 1.00mm Round Cut Black Sapphire

 

Sapphires may be treated by several methods to enhance and improve their clarity and color. It is common practice to heat natural sapphires to improve or enhance color. This is done by heating the sapphires in ovens to temperatures between 500 and 1800 °C for several hours, or by heating in a nitrogen-deficient atmosphere oven for seven days or more. Upon heating, the stone becomes more blue in color but loses some of the rutile inclusions.
