Summary edit

Description
English: Danalite
Locality: Rockport, Essex County, Massachusetts, USA (Locality at mindat.org)
Size: 7.2 x 4.8 x 3.2 cm.
From the TYPE LOCALITY where it was first noted in 1866, this is a superb, intensely colored danalite crystal, named after the great mineralogist. The crystal is approx. 2 cm tall. Danalite turns out to be a rare member of the helvite group, seldom crystallizing and most often found as masses in rock. Here we have a superb 3-dimensional crystal perched on matrix with amazonite feldspar and cryophilite, in quartz. According to MINDAT, cryophilite has been discredited by the IMA Mica subcommittee. It is now considered an odd variety of Zinnwaldite, Fe-bearing trilithionite, or Fe-bearing polylithionite (again, according to MINDAT). Ex. Academy of Natural Sciences Philadelphia Collection.
