Microminerals and Micromounts: A thru L- generally require magnification. Matrix is usually TN (thumbnail) or smaller.

Update March 21, 2008:  We apologize for the long time of not updating this page.  We are planning to upload new specimens in the next week or so.  We have quite a few microminerals available;  if you're looking for something specific please don't hesitate to ask.

For an explanation of abbreviations used, please see our guide to mineral sizes.



Anatase - Holmstrand, Norway.  Several black, shiny, sharp, bipyramidyal anatase xtls.  Also some very tiny yellow xtls of Parisite-(Ce).  Best at 20x or higher. Unmounted.
#M271.... $5.00




Azurite - Kelly Mine, Magdalena, NM.  Blue, lustrous micro xtls in limonitic matrix.  With minor malachite, etc.  Best at 20x or higher.  Unmounted.
#M278 ... $3.50



bastnaesite Bastnaesite-(Ce) - Poudrette Quarry, Mont Sainte-Hilaire, Quebec, Canada. Greenish-grey micaceous flakes & masses on matrix. At least one (shown) is a well-formed hexagon.
Sugg. 30x or better mag.
Puttied in a "Perky" box with printed label. #M246 ... $5.00


Calaverite and/or Krennerite (AuTe2) - Cresson Mine, Cripple Creek, Colorado.  Gold telluride.  Striated, metallic, subhedral xtln., in gray matrix.  Sugg. 20x or better mag.
#M276 ... $6.00



hauyne specimen for sale   Hauyne - Niedermendig, Eifel, Germany.  Sky blue anh. xtln. grains in matrix.  One seems to have an actual xtl face.  Hauyne, like sodalite,  doesn't usually form well-defined xtls.  It most often appears as vitreous blobs.  #M251... SOLD


    Hematite, Quartz, and ? - Nine Mile Pluton, Wausau Complex, Marathon County, Wisconsin.  The dark, silvery mirror-like flakes are hematite.  I'm not entirely certain about the thicker, tabular xtls near the quartz (tantalite / columbite?).  The pegmatites of the Nine Mile Pluton contain quite a variety including several rare-earth minerals.  There is a paper by A. Falster et al. that details the minerals of the Wausau Complex, with SEM photos.
Puttied in a prepared M511 box w/ label.
#M256 ...Sold

Garronite - Galboly, Garron Escarpment, County Antrim, Northern Ireland.  White, fibrous, crystalline masses.  Not very exciting to look at, but an unusual species and also the type locality for this mineral.
#M273 ... $3.00



Heulandite - Veneto, Italy.  Small, shiny, transparent cluster of xtls with a faint yellowish cast.  Visible at 10x or higher.  Unmounted.
#M272 .... $4.00

Ilmenite - Tosca Quarry, Varsi, Parma, Italy.  Tiny, sharp, lustrous micro xtl in a cavity in matrix.  Vis. at 10x, but higher mag. suggested.

Kinoite & Apophyllite - Christmas Mine, Arizona.  Micro xtls of apophyllite (colorless, clear) with blue kinoite. Small matrix, micromount size (unmounted),  rich in both minerals.
#M277 ... $4.50
