Of all the habits exhibited by Bunker Hill pyros, the curved crystal habit as shown by this specimen is the most unusual and coveted. The lustrous and slightly translucent crystals reach 1.5 cm across and are aesthetically emplaced on orange colored arsenian pyro crystals. The curved crystals are slightly coated or included, giving them an unusual green color. If bright green, the specimen would have been a world class thumbail.
