517ct Hornblende Crystal from Tanzania

This cool & very dark hornblende crystal shows almost no color unless back lit by a very strong light. The only sections that will show the green on this piece are some of the edges of the crystal and it takes a direct strong light. While dark (appearing black with a very slight green luster in normal lighting), I really like the crystal structure. A neat piece from Tanzania! We consider this piece to be a (SMC) Small Cabinet sized mineral specimen.
