A half-dozen globes of white thomsonite lie on a crust of heulandite in this specimen. The thomsonite balls have a distinct texture, looking very much like tiny snowballs (although having a slightly off-white color). The heulandite crystals are transparent and colorless. Tiny amounts of another mineral disturb the perfection of the thomsonite balls by giving an appearance of dirt on the surface, in several small areas. Still, this is an unusually nice specimen of this rare mineral.
