Sal Ammoniac (RARE style - classic locale)

Item Description

Salammoniac, an uncommon halide, is rare from anywhere but especially this famed, classic volcano. Most such specimens have trapezohedral isometric form or are massive. This is an EXTREMELY RARE, very large elongated terminated rhombohedral crystal from here! Perhaps a unique example of this style in huge size for the locale. Probably older material, but no proof. The specimen was tested and confirmed in 2000. Ex Hemel Collection. A MUST for the locality or species locality!
