Thomsonite

Item Description

Going back to the late 2000s, there was a discovery of some of the best pieces of the relatively rare zeolite species Thomsonite in India. I think by this point, 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 good quality, light creamy-pink colored sphere of Thomsonite measuring 4.7 cm sitting on brown contrasting basalt matrix. The main sphere is in excellent condition, with no major damage. A beautiful display piece of one of the rarer Zeolite species out there. Valued at $1,800. From the collection of Vasco Trancoso, a medical doctor and prominent mineral collector from near Lisbon, Portugal (https://www.mindat.org/user-11954.html). He assembled his mineral collection over the course of 60 years, and built a fine worldwide display collection that we recently purchased.
