Topaz IMPERIAL Terminated Crystal, Golden Orange, 21 mm long
Weight: 4.03gm 20.05ct
Dimensions: 21x13x7mm (25mm= 1 inch)
(#27) Crystal is transparent/translucent – visible inclusions, or internal fractures running through the center of the crystal, reflect incoming light with rainbow colors. This effect is similar to the Schiller effect in opals, and is to my knowledge only found in the imperial topaz from the Ouro Preto mine in Minas Gerais, Brazil.

I began selling gems and minerals and studying gemology in the late 1980’s. I traveled around the states with gem/mineral and craft shows for a couple of years before settling in Gainesville, FL where I opened a shop called The White Cloud. In 1992, I got a job counseling, packed all the store stuff away and forgot about it until now. What a surprise to find these beautiful crystals and minerals after all that time…
