Cavansite & Pentagonite, well protected by the dynamic undulations of the gemmy Heulandite on Basalt matrix are fantastically formed, with undamaged, terminated spikes on the Pentagonite.

This legendary location has been both closed and overbuilt, making these rare crystals increasingly hard to find. 2" x .8" x 1", 1.1 oz.
