Collection: Heat Kashmir

Greater than 95% of the world's sapphire and ruby are thermally enhanced with higher temperatures.  The heating process is both an "art & a science" requiring the perfect recipe of time, temperature, and atmospheric condition to 'enrichen' the color.    Our low pressure  low temperature process develops the optimal blue leaving the signature velvet texture by replicating the deep earths natural conditions.  Our process is slow and gradual over days and or weeks of time.  A large contrast to the new thermally shocking 'high pressure high temperature' (PHT) technologies that press a stone under 15 minutes @1000+ atm like creating HPHT diamonds.
