Fabulous specimen of rare Garnet var. Grossular with green phantoms. Grossular crystals are gem, with  green cores, which are result of Chromium, surrounded by transparent, colorless areas. The crystals have rhombic dodecahedral sharp crystallization, good luster and irresistible contrast. Some green Diopsides are seen too. Green cored Garnets are among the most unusual and rare Jeffrey mine Garnets. This was mined long time ago - the mine is inactive now. For references see the issue of The Mineralogical Record vol. 44, # 4. In good condition - some contacts on the back side. On acrylic base.

Gorgeous phantom Garnets!
