Analcime - Sold

Analcime is a hydrated sodium aluminum silicate, a member of the zeolite group (Coombs et al., 1997). Haüy (1787) named the mineral from Greek root for weak, due to its weakly electrostatic nature. At Mont St. Hilaire, the mineral forms trapezohedral crystals to several cm.

This analcime is a complete trapezohedral crystal. The color is stark white, much like a fine porcelain. This specimen was part of the Carlton Davis thumbnail collection. It remains his "Perky" box with a typeset label attached to the inside back of the colorless top of the box.
