Treatment: Assume heat, as is common and acceptable with Topaz from this region.
Note: This is a fine color genuine Imperial Topaz from the world-famous deposits of Ouro Preto Brazil! An older stone mined in the 1960s is rarely available on today's market! No coatings, diffusion, or any treatment gimmicks... just a special gem-grade Imperial Topaz with a pretty peach-orange color!
