A sizable and very fine cabinet specimen of well-crystallized Brewsterite from the type area for the specie. Brewsterite is the less common analogue of Heulandite and can be Sr or Ba dominant. This specimen is almost certainly the Sr dominant version though not tested. This has hundreds of well-formed crystals which are transparent to translucent and very lustrous. Ex Hitchings collection this is an older specimen that was obtained in trade. Excellent undamaged condition.
