Globally recognized for the Punsiri heating

His interest in this discovery prompted him to start his own heating experiments in gems. He found a way to heat the gem, so as to bring out the best blue out of blue sapphires. The color created was unique, beautiful, and wonderfully dispersed throughout the gem. It was at this time that allegations were made against Punsiri saying he must have used unethical treatment or must have added chemicals in the heat treatment.
