This specimen is one of the most 3-dimensional and aesthetic of the lot, in association with crystallized quartz martrix. It features a central crystal of 3 cm (beautiful, but I need to say has a slightly bruised upper corner that gets lost in the crowd, anyhow), and perched atop it are two pristine, complete, GEMMY, RAZOR-SHARP, 2-cm crystals. Those crowning crystals are so gemmy that you see through them to the thin shard of iron-stained quartz running up the middle of the crystal cluster. In person, very impressive!
