Here is a wonderful specimen of gem 'ruby' sphalerite from the old La Mure coal mines in the Alps!
It displays a very large (3.4 cm) and lustrous polysynthetic-polytwinned crystals of red color with golden orange hues, sandwiched between white dolomite crystals.
You can also see from the back of the specimen there is a more cleiophane core.
Truly a superb French alpine classic, considerably hard to find in this quality and size!
Discovery by miners in the 1980's.
