Heulandite - historic, ex Robert Ferguson (Ref: 1078-JM-3710)

Teigarhorn, Berufjordur, Suour Mulasysia, Suour Mulasysla, Iceland
88mm x 70mm x 37mm
minID: 7RY-XXP
Heulandite crystals in a pinkish Natrolite vug from the famed collection of Robert Ferguson (1767-1840). This was obtained by John Marshall in 1998 when the collection was rediscovered and sold-off in lots. This piece, like many others, does not have a label, so some details are lost, but the collection lists pieces from Berufjordur so this given locality is a speculation. However this seems very likely as this matches specimens from here very well, and Heulandite was a new mineral in the years that Ferguson was actively collecting. Crystals reach 1.7 CM and are the typical sharp, glassy partly transparent type well-known from this region of Iceland. Some penetration twins of the prisms are distinctive. No damage.
