Uncommon combination of grass green Garnet var. Grossular var. Chromian with Prehnite. The Grossular crystals are gem, to 1mm with rich green color, which is result of Chromium. Dodecahedral sharp crystallization, glassy luster and irresistible color. Some cream colored Prehnite enriches the display. They have two habits. Very interesting specimen from this great and closed mine. For references see the 2013 issue of The Mineralogical Record vol. 44, # 4. Some damages. On acrylic base.
Superb!
