Description

A very rare member of the zeolite-family. The clinoptonolite crystals formed spheroidal aggreates in intense red color. The contrast with matrix is really nice. Next to rarity I really like this amazing assemble in the center of the piece which reminds to spread eagle on a coat of arms. Should be high ranke for rarity and classic locality.
