Treatment

The note in the certificate "Signs of a thermal treatment" suggests that the stone has undergone a heat treatment. Such treatments are very common and standard in the trade. Heating, also called "firing," is a science in itself. The specialists keep their "recipes" strictly secret. Firing is used to permanently enhance both the color and the clarity of a stone.
