Laumontite - rare large XL (Jaime Bird Coll.)

Item Description

Laumontite (hydrated calcium aluminum silicate) is a rare California zeolite mineral; even many zeolite collectors do not have one, as they are very uncommon on the market. This is a fine, sharp cluster of terminated, lustrous, creamy, crystals. Excellent material from this extinct locale. Ex Jaime Bird Collection.
