Heat Treatment

Ancient Egyptians used to simply place natural mined Rubies into fire for extensive amounts of time. During this process, black carbon and surface impurities were pealed off by the fire and degree heat. The same practice is still used today with Gemstones. Natural gemstones react to heat and are commonly used as standard natural gemstone cutting process. Gemstone is heated to high degrees which is called gemstone heating.

Most real Blue Sapphires today are heated to high degrees during natural faceting process. Anyone claiming that natural mined real Blue Sapphire is not heated during natural faceting process, is something very unusual and highly questionable. Typically when verified such unusual claims, that natural Blue Sapphire Gemstone is not heated or other eccentric index statements, such are 99% of times false claims.

There are many Sapphires that are not heated at some point. However, since a majority of Blue Sapphires are processed from rough to any given jewelry piece today with heat associated, it is highly recommended to verify any unheated advertisements with you local Gemologist.

Many like to advertise with unheated false claims knowing that people new with gemstons might think heat is something bad or even fake, while in fact part of the natural gemstone process from rough to jewelry piece.

Color irritations and color chemical applications should not be confused with natural faceting and gemstone heating. Gem Trade word treatment is important to double check, since as per The Lapidary Journal, many tend to consider as something bad apart of its entire context. Not that same as irritations or color chemical applications. If one wants to seek non heated blue Sapphires, then one must use extreme caution since such are generally very rare.

Another aspect with heat is that some gemstones simply do not or would not exist without heating process. F.ex. There are no such thing in the world as non heated Blue Topaz. Every natural mined real Blue Topaz is heated during natural faceting process. While a hand full of Blue Topaz rough have been found in the world, those are very pale in blue and in museum display level items. Topaz, in its natural rough form is a dirty white gemstone. Again, anyone claiming that they are selling unheated Blue Topaz, is Gemologically false statement.

It is important to always use caution from any item sold anywhere, wether in retail stores or on Ebay. Any claims of non heated stones today can be often verified false by your local Gemologist. As always, it is recommended to require such in writing and most importantly with full money back guarantee as well as payment protection.
