Epidote


Epidote
The chemical formula for Epidote, according to Wikipedia is Ca2Al2(Fe3+;Al)(SiO4)(Si2O7)O(OH).  I found only one thing about its uses.  The dark spot in the image and in the following image is Allanite, a related species.

Epidote with Allanite
The crystals in this samle are small.  Without looking closely enough I would never have recognized it from the description.  I can only begin to see the transparency of the crystals in this 8x image.  It is an igneous rock.  The size of crystals varies greatly (to 35 cm).  It also occurs in secondary metamorphic rocks such as marble.

The large crystals with are perfectly transparent have been ocassionally cut as gems.
