SAPPHIRE & RUBY HEAT TREATMENT SERVICES

WHY HEAT TREATMENT NEEDED IN SOME SAPPHIRES & RUBIES (CORUNDUMS)
To improve the Color and to bring Brilliance ( Improve Clarity) of the Rubies & Sapphires. Certain
type of Origins of Sapphire and Rubies do not give 100% positive result on heat treatment always.
Today’s Market you find 90% of Sapphires are Heated in traditional method to improve the color and clarity.

What Heat treatment does to the Natural Sapphires and Rubies.. ? Certain type of un-dissolved natural impurities (Chemical elements) which is presented in the natural rough stones (corundum’s) can be dissolve by very high heat and could turn them to improve color and to open the crystal of the gems in to a transparent gem instead of semi- transparent, translucent and in some occasion translucent to opaque type of gems. Mostly Blackish Blue Sapphire are unable to change in to lighter color by heat Treatment but Sapphire with lighter color or colorless(with slight presence of un-dissolved chemical elements being in stone, such as Geuda) can be improved by treatment (color and clarity). Most Sapphire rough coming out of USA mines (Montana ), no need to do pre-shaping or trimming (to remove certain type of inclusion to avoid cracking and shattering in high heat). Crystal structure formation on Montana Sapphire allows us to heat treat them as is without pre-shaping,most of other origins need to be pre-shaped and trimmed (removing certain type of inclusion prior to treatment to avoid cracking & shattering ).For pre-shaping ( removing certain type of inclusion ), we need to charge a small fee. Further your rough stones will loose slightly weight on pre--shaping (pre-forming).If you're not family or do not know to figure out the out come of the Heat Treatment... its advisable to Heat-Treat a small Quantity like 50 carats (10 grams). To get an idea of the result of your rough stones before going on to larger quantity.
