Laboratory Created Gems - Flame Fusion or Verneuil Process
This method utilises the powdered ingredients of a gem by fusing them together under a high temperature oxy-hydrogen flame. The ingredient powder melts and crystallises in successive layers. This type of synthesis uses an aluminium oxide powder doped with trace elements to create laboratory corundum of various types. It is also used to make lab spinel using another combination of elements.
The process is a scientific laboratory crystal production method and offers very good value for money. Laboratory gems are therefore very affordable.
The chemical make-up of a laboratory created gem is identical to it's more expensive natural counterpart. Gemologists find it very difficult to identify with the naked eye and sometimes even under 10x magnification. It is also the reason that laboratory created gems are not classified as synthetic gems.
Natural gems are gorgeous but incredibly expensive, especially when it comes to the large, bright and top quality varieties that are extra difficult to find. They are flawless in appearance and they cost only a fraction of price of natural gems!
