This specimen is highlighted by large, intergrown, lustrous, black schorl crystals, to 2.5 cm; and glassy and gemmy, intensely colored, blue aquamarine crystals, with one to 6 cm in length. The three largest aqua crystals are doubly-terminated! And pristine... At the bottom of the specimen, two aquas are broken at the base, but this pales to insignificance. Otherwise all is complete and the contrast of blue on black is, really, striking.
