  • Mineral Type: Thomsonite is a rare member of the zeolite group, composed of hydrated sodium calcium aluminum silicate.

  • Formation: Found in vesicles of volcanic basalt, especially along the North Shore of Lake Superior, where ancient lava flows created ideal conditions for zeolite crystallization.

Collectibility and Significance

  • Rarity: Thomsonite is among the rarest zeolites, prized for its aesthetic qualities and limited geographic occurrence.
