A cluster of INTENSELY gemmy - the absolute top in quality - apophyllite crystals, beautifully centered on a matrix of silky stilbite crystals. I think the pics show pretty well how amazingly glassy and fine these crystals are - the best of the best, as they say! Though there are plenty of zeolite specimens out there, very few reach this level of quality. 5.1 x 5.1 x 4.4cm
