Thomsonite (rare) with Stilbite

Item Description

A few years ago there were some inds of the relatively rare Zeolite species Thomsonite in India. Most people are probably familiar with these rather smooth spheres that are found on basalt. They don't look like Thomsonite that I've seen from any other locality. This is a great display specimen from the same locality featuring a pair of good quality spheres of Thomsonite measuring up to 2.2 cm with minor bladed off-white Stilbite crystals on basalt matrix. A beautiful display piece of one of the rarer Zeolite species out there.
