Imperial Topaz

Do you think, there is an important difference in terms of price between the natural and the treated imperial topaz?
(irradiation or heating for example)

I won’t use any heat treated topaz or any other gem. It cost more but I only will sell the natural stone. That’s why I only have the natural Imperial,sherry, and blue topaz from the mine I used to work

Woolsey, u might appreciate this pend, natural pink Brazilian topaz & bi-color tourmaline, both @11cts and almost flawless-steve…
