Prehnite Sgurr nan Cearcall, nr Glen Brittle, Isle of Skye, Scotland, UK FOV 7cm x 5cm Nice green and quite lustrous prehnite crystals forming thick crusts in very hard basalt. Open and vuggy material, often with little epimorphs(?) or casts of prehnite on calcite (presumably) to 3mm across, but the casts are hollow. Self-collected 1997 (Author: Mike Wood)
