Description

You are bidding on a large sample with vugs hosting prisms of laumontite from the Foote Mine. Laumontite from pegmatites is very unusual and this find in 1982 was no different. Laumontite from the Foote Mine also has a small concentration of Be, making the crystals more stable than most localities. Even after almost 40 years the crystals are still partially transparent. Very rare from the locality.
