BERTRANDITE   Aggregate Industries Quarry, Raymond, NH
0.7 mm clear crystal cluster
Species:           BERTRANDITE  
Locality:          Aggregate Industries Quarry, Raymond, NH
Specimen Size: 0.7 mm clear crystal cluster
Field Collected: Tom Mortimer
Catalog No.: u2323
Notes: Brookite and bertrandite are other possible ID's for these.
These AIQ crystals do have some appropriately oriented striations (that bring to mind a brookite ID ... suggested by Bob Wilken). The AIQ ones do not have the elongate habit seen in many of the mindat baddeleyite photos. Most of the similar, clear, mindat ones come from volcanic complex environments (Italy & Germany), like the AIQ environment. There are a few tiny zircons also on this specimen. Zircons are more common at AIQ (Zr - favoring baddeleyite) but we also have uncommon anatase (Ti - favoring brookite).

BERTRANDITE   Boulder field, N. Sugarloaf Mtn., Bethlehem, NH
1.2 mm cluster bertrandite crystals
Species:           BERTRANDITE  
Locality:          Boulder field, N. Sugarloaf Mtn., Bethlehem, NH
Specimen Size: 1.2 mm cluster bertrandite crystals, two views
Field Collected: Tom Mortimer
Catalog No.: u2378
Notes: Collected from the large boulder pipe in the boulder field. These are thin, platy, bertrandite crystals. The bertrandite crystals from the N. Sugarloaf smoky quartz area are prismatic (multiple photos on this web site).
Not a lot of contrast available for this small crystal group.
Top photo taken with Canon SL3 and Nikon Plan 10 objective, a stack of 20 images. Lower photo with Canon G9 through Meiji trinocular scope, a stack of 6 images. The Meiji scope configuration provides about a 90 mm working distance, permitting a much better lighting angle than the Plan 10 photo with but an 11 mm working distance.
Third photo with Canon SL3, 4x objective, 25 mm working distance, 50 image stack.
Note the vertical line twin plane of the foreground crystal shows in all photos.
