Thomsonite

Rare Opalescent Lake Superior Thomsonite

This stone is what I might call a 'Super Prehnite'.  According to Bob and Dan Lynch (Lake Superior Rocks and Minerals), "it is the most valuable and sought after of Lake Superior's many Zeolites.  The best specimens have deep pinks or greens."  This specimen is an intense, opalescent pink which shimmers in the light.  Also contains epidote and white prehnite inclusions. The accompanying basalt pedestal has a natural indentation for a special display.
