Identity HelpVery strange Topaz Crystal
17th May 2015 08:31 UTCHubertus (Hu) Hühne
Out of an old collection comes this very strange, broken topaz crystal with no locality (maybe USA if I look at the rest of the collection).
Measures 8.8 x 6.4 x 5 cm
It stands on a cleavage. One side is vertically striated, one side seems to be very oddly broken (no cleavage visible) and healed.
But the most important is the one surface with the "pockmarks" - six edged windowed crystal shapes raised from the surface, all "hollow" (impressed inwards like a window crystal - increased edge growth?), outsides are vertically striated. Can somebody explain this topaz to me and maybe suggest a locality?
Many thanks! Hu

I do wish people would label their specimens! Label, Label, Label!

But I am no crystallograph.
Good luck.
