Unheated Sapphire - Best Loose Unheated Sapphire for Jewelry
The ruby and sapphire, or corundum world is divided into two camps, the natural heat treated ruby gems and heat treated blue sapphire and the natural unheated-untreated ruby and sapphire gemstones. About 90% of all sapphire available in the gem markets are heat treated. AfricaGems is very fortunate to have an incredible inventory of natural unheated blue, pink, yellow sapphire and purple sapphires in stock. These sapphires have not undergone any kind of thermal or other types of gemstone treatments. We won't talk about chemically diffused sapphires as these are another entirely different topic and AfricaGems.com doesn't sell these artificially colored sapphires.
Blue Sapphire Treatments
Sapphire has been mined for thousands of years and sapphire heat treatment has been known for many years and mastered by the Thai ruby and sapphire gem dealers in more recent years. In Sri Lanka, a primary source for sapphire, most sapphire rough gems are mined as "gueda". These gueda sapphire crystals are not transparent due to numerous rutile inclusions and appear to be almost milky in transparency and color. In the 1960's Thai corundum dealers discovered that when these "worthless" gueda were heat treated, some of the results where nothing short of miraculous. These heat treated gueda sapphire resulted in incredible cornflower blue sapphires! When heated to very high temperatures, the internal inclusions "melt" away, and the transparency or brilliance, color and overall appearance of the sapphire is greatly improved. Even very attractive sapphires that have only a few inclusions will be heat treated to bring out the very best color and brilliance possible. Untreated sapphires command the highest prices as they are much rarer than equal quality sapphires that have been heat treated. Untreated blue sapphires make wonderful gemstone rings .
