Thomsonite

Mineral specimens of any species are rare from this little-known zeolite locality in Oregon. This specimen showcases two snow-white spheroidal clusters of radiating thomsonite, in a vug lined with what appears to be sharp, glassy, white, pseudo-rhombic chabazite crystals on a volcanic matrix. The thomsonite “balls” measure up to 1.0 cm making for a great miniature example from an obscure but mineralogically intriguing locality.
