A rather unusual specimen featuring, instead of a spherical aggregate of small crystals, rather large crystals arranged in a radial spray. In fact, we have here two crystal groups, one atop the other. It has good color, but effectively no sparkle - it has a matte luster to the surface. Still, it is dramatic, large, and significant for the species in the size and habit of these radially grown larger crystals (to 4 cm). The association seems to be pectolite, but I haven't had it tested to be sure. None of my other specimens have this matrix, leading me to suspect this unusual specimen was formed under threshold conditions at the edge of the main pocket, apart from the rest.
