All, I recently saw a cut stone on a site that was called
Bertionite, aka Tiffany Stone. I have some of that material and have
cut a number of stones but was always under the impression that it
was a massive opal material from some deep mines in Utah.
I have checked at Mineral Galleries on-line, and all of my
mineral/gemstone reference books but cannot find any on
this stone. Can anyone out there help out?
