MD-199958 - Danalite - - Archived Rockport, Essex Co., Massachusetts, USA cabinet, 14.0 x 12.4 x 7.1 cm.
14.0 x 12.4 x 7.1 cm. Danalite is a member of the helvite group, rarely crystallizing. This is a large specimen with a massive embedded crystal of beautiful pink-red danalite, showing some fracture faces. What is more, it is from the old TYPE LOCALITY (from which it was described in 1866). Ex. Philadelphia Academy of Sciences Collection.
MD-202027 - Danalite - - Archived Rockport, Essex Co., Massachusetts, USA small cabinet, 7.2 x 4.8 x 3.2 cm.
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.

From the TYPE LOCALITY where it was first noted in 1866 during the Civil War, this is an OUTSTANDING, aesthetic, 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 (betcha didn't know the world had such an important body of governors...). It is now considered on odd variety of Zinnwaldite, Fe-bearing trilithionite, or Fe-bearing polylithionite (again, according to MINDAT). The danalite crystal is 3-D, attractively displayed, and overall we hav ehere both a significant and attractive display specimen of something so rare and historic that most of us will probably never see again.
