38626: Tourmaline and Quartz - $10 Himalaya Mine, Gem Hill, Mesa Grande Mining District, San Diego County, California Miniature - 4.3 x 3.5 x 3.3 cm 56 grams Specimen status: Available Send an email with specimen number to order A 1.8 cm, translucent and terminated
tourmaline crystal which I have excavated from its
enclosing massive quartz matrix. The tourmaline has
several parallel white lines, caused by recrystallization
after a pocket rupture/crystal break event. Such
break/heal events are globally uncommon in tourmaline yet
found frequently at this locality.
