Thomsonite (rare locale)

Item Description

A shock went through the Denver Show a few years back when word got out that these zeolite balls from India, unbeknownst to the dealers who brought them over, were actually the very rare THOMSONITE, rather than some other zeolite. They were all bought up immediately, of course, because thomsonite had never been seen in such big, rich and actually pretty specimens - forming perfect and sometimes large spheres. These measure to 3.7 cm - a chain of eleven intergrown balls. The spheres are opaque and creamy white to very pale orange and are composed of radiating acicular crystals, resting directly on brownish gray basalt matrix. A rare, dramatic and excellent elongated specimen.
