Over ~90% of all gemstones in the marketplace have undergone heat treatment to improve the stones color & appearance. Basic or low heat treatment is one of the treatments which are acceptable in the trade because the results are permanent, do not require additional special care by the consumer and does not change the gem's chemical composition. In the trade, the overall value of a gemstone is not affected if it has undergone low heat treatment. Alternatively, an unheated gemstone can carry a 25%-35% price premium. Owning an unheated gemstone has historically been reserved for the serious collector due to the rarity and price premium associated with unheated vs heated.
