Locality: Palermo #1 Mine, Pod 3 N. Groton, NH
Specimen Size: Largest crystal is 0.3 mm
Field Collected: A purchased specimen
Catalog No.: u650
Notes: This is my NH species display specimen - another view. Original photo taken in 2010 is improved here. Although the crystal in the photo looks quite apatite like, the stippled termination, flattened hexagonal shape and pale green color are an excellent match for the Greifensteinite rendering in Bob Whitmore's book, The Pegmatite Mines Known as Palermo".
Locality: Chandlers Mill Mine, Newport, NH
Specimen Size: 3 mm field of view
Field Collected: Bob Wilken
Catalog No.: A Bob Wilken specimen and photo
Notes: The roscherite group includes greifensteinite. For the time being, I am grouping related minerals under the greifensteinite species.
Locality: Chandlers Mill Mine, Newport, NH
Specimen Size: 1 mm roscherite group mineral fan
Field Collected: Bob Wilken
Catalog No.: A Bob Wilken specimen and photo
Notes: The high luster of these crystals makes it difficult to take a photo without at least some bright reflections.

Field Collected: Bob Whitmore 1975
Catalog No.: A Bob Whitmore specimen
Notes:
Locality: Palermo #1 Mine, Pod 3, N. Groton, NH

Notes:
Locality: Palermo Mine, N. Groton, NH
Specimen Size: 1 mm field of view. Stubby, hexagonal, prisms of griefensteinite.
Field Collected: From a box of small rock chunks gifted by Bob Whitmore
Catalog No.: u1524

Specimen Size: 3 mm field of view. Dense cluster of hexagonal prisms of griefensteinite.
Field Collected: From a box of small rock chunks gifted by Bob Whitmore
Catalog No.: u1529
Notes: As shown in Whitmore's book The Pegmatite Mines Known as Palermo (pg. 131) the haxagonal face on this griefensteinite habit somewhat rough and reflective.

Specimen Size: 1.5 mm spray
Field Collected: ex. Jim Warner
Catalog No.: A Bob Wilken specimen
Notes: [bw] I came across another Palermo one that has me scratching my head. They look like flat laths, so much so that at first I thought it could be parascholzite but color is all wrong and the laths are kind of crinkly looking. A tentative ID is greifensteinite.
