NATURAL NO HEAT SAPPHIRE
Natural, top quality Sapphires which have not been heated are scarce and considered most valuable by gemstone experts. Sapphires are commonly heated to modify their color and appearance.
The demand for natural, unheated Sapphires keeps growing while the supply of such gems remains limited, making natural Sapphires of gem-quality from all major sources difficult to find.
Sapphire is the birthstone for September, and it is also the celebrated 5th Anniversary gemstone.
