Item Description

A RARE specimen of Himalaya Mine laumontite - not something you see around on the market much, even if you are a Himalaya fan keeping an eye out for specimens. Laumontite is a zeolite, a hydrated calcium-aluminium silicate, with the molecular formula Ca(AlSi2O6)2 ?4H2O. This cluster of fine prismatic crystals is in wonderful condition, with the terminations intact.
