Description: Apophyllite + Thomsonite Moonen Bay, Isle of Skye, Scotland, UK Crystals 17mm + 22mm Nice pair of larger apophyllite crystals from the same cavity, on a thin slice of basalt matrix, with white thomsonite. A feature of these apophyllites is the smaller thin crystals penetrating the larger ones; very interesting when magnified. Collected 2013.
