Here is a large and colorful specimen which features dark green tourmaline crystals set on bladed sky blue cleavelandite crystals.  The tourmaline crystals, which are up to 1.2 long, are nicely striated and glow a rich green when backlit.  The cleavelandite is an exquisite light turquoise blue, with typically bladed crystals up to 4".  The tourmaline grew on the inside lining of a pocket that was surrounded by cleavelandite.  There are also some black schorl tourmaline crystals on the pocket lining.
