SAPPHIRE HEAT TREATMENT SERVICE, HEAT TREATING SAPPHIRE
.
Why heat treatment needed on Sapphire ? To improve the Color of the stones to
Darker Color or to bring Brilliance (Improve Clarity) to the stones.Sapphires from certain
countries ( Certain Origins of Sapphire ) don't give positive result on heat treatment always.
Today's Market you see 90% of Sapphires are Heat Treated. Darker Blue Sapphire's (Blackish
Blue) are unable to change in to lighter color by heat Treatment. Sapphire with lighter color or
colorless ( with presence of undisolved chemical elements being in stone, such as Geuda) can
be improved by heat-treatment ( color and clarity ). Most Sapphire rough coming out of USA
mines ( Montana Sapphire), no need to do pre-shaping or triming ( to remove certain type of i
nclusion 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 orgins need to be
pre-shaped & trimmed(removing certain type of inclusion prior to heat 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).
