Fabulous thumbnail specimen of very rare Garnet var. Grossular with grass green phantoms. The Grossular crystals are very gem, with dark green cores, which are result of Chromium, surrounded by transparent, colorless areas. The crystals have rhombic dodecahedral sharp crystallization, glassy luster and irresistible contrast. The green cored Garnets are among the most unusual and rare Jeffrey mine Garnets. This was mined long time ago - the mine is closed now. For references see the 2013 issue of The Mineralogical Record vol. 44, # 4. In excellent condition. On acrylic base.
Gorgeous phantom Garnets!
