Actinolite - Ducktown, Tennessee.  Coarse blades of pale green to brownish-green actinolite.  Puttied in a paper box.
#M292 ... $2.50

Chalcocite, Calcite, and an unidentified dull yellowish-tan mineral - Watchung Mountains, New Jersey.  Someone out there probably knows what that third mineral is;  we haven't had time to do the research.
Specimen puttied in a white paper "micro" box.

#M297 ... $2.50







Chrysocolla, "stalactitic" form - Morenci, AZ.  Puttied in a small paper box.

#M294 ... $2.50

hauyne specimen for sale

Hauyne - Niedermendig, Eifel, Germany.  Sky blue anhedral xtln. grains in matrix.

Hauyne, like sodalite, doesn't usually form well-defined xtls; it appears as vitreous blobs.

Photo shows a representative specimen
but not the exact one you are buying. We have a couple of these available.

#M251...$7.00

Quantity:



Hematite
on calcite.  Buckwheat Pit, Franklin, NJ.   A tiny cluster of botryoidal hematite, surrounded by a ring of hematite having a radial appearance.  Matrix is tiny, typical of a micromount, but is Unmounted.

#M299 ... $1.50



   
Hematite, Magnetite / Franklinite, & Calcite.  Buckwheat Mine, Franklin, NJ.  Small crystals (with parting) in calcite on top of some massive magnetite-hematite-franklinite ore.  A couple of small, complete xtls and several partials.  Some have a multicolored iridescent coating (copper secondaries, perhaps), and also a whitish secondary coating that could be smithsonite.
Complicating identifications in this assemblage is the fact that magnetite and franklinite can occur exsolved within one another;  likewise hematite.
TN size specimen, puttied in a Jousi-style Euro box (nice label on underside).

#M300 ... $8.00





Hematite, Magnetite / Franklinite, & Calcite.  Buckwheat Mine, Franklin, NJ.  This assemblage, like M300, would have been mined from the Buckwheat Pit mine.

Mostly massive, metallic-gray hematite;  there is one nice, complex micro xtl on this specimen (along right-hand edge;  30x recommended).  Lg. TN size matrix.  Puttied in white paper box with a nice label.

#M301 ... $4.50

Christmas Mine
Gila County, AZ

Rich blue kinoite on matrix, with minor amounts of gilalite (green) and ruizite (reddish-tan).  Puttied in a Finn-style micromineral box.  The kinoite micro xtls are numerous on this one.

#M219 ... $7.00
