MIN#EXCEPTIONAL-81 NEW!

Classic specimen of Acanthite cubes in cluster from Germany!
True museum quality Acanthite specimen that is actually from the Smithsonian Institution Collection! This is a Freiberg
Acanthite, circa mid 1800's, which is every bit as impressive as its provenance. Specimens of Silver minerals from Freiberg
are European classics, if not world classics. Acanthite is the stable, low temperature form of the Silver species Argentite.
These crystals are very attractive with their superb luster and varied cubic forms. The largest complete cube is 1 cm across,
and all are very sharp as they line up perfectly. Bosch and Smithsonian labels are included, showing off the great provenance.
From the
Himmelsfürst Mine, Brand-Erbisdorf, Freiberg District, Erzgebirge, Saxony, Germany.
Measures 3.2 cm by 2.1 cm by 1.9 cm in total size.

MIN#EXCEPTIONAL-82 NEW!

Absolutely gorgeous and glassy crystals of emerald-green Dioptase with Calcite on Duftite covered matrix!
One of the prettiest combos you'll ever see from the Tsumeb Mine and in my opinion, even prettier than
the more common Dioptase on white Calcite specimens. The Dioptase crystals are in excellent condition
with only a few minor contacts. They are accented by white Calcite crystals on a matrix surrounded by
yellow-green Duftite. Stunning specimen and very well trimmed. The Dioptase xls measures to 1.8 cm.
From the Tsumeb Mine, Tsumeb, Otjikoto Region, Namibia.
Measures 4.8 cm by 9.2 cm by 4.3 cm in total size.

Tucson2013-333AzuriteMalachiteApexMineStGeorgeUtah.jpg (369167 bytes)

MIN#EXCEPTIONAL-86 NEW!

Colorful cabinet sized plate of Azurite with Malachite!
Of all the Azurite specimens I see from Utah, the Apex Mine is one of the scarcest localities.
Cabinet sized plates are even rarer. This specimen is a beautiful example which displays at least
two color variations of Azurite along with a botryoidal form and a micro-crystalline form which
sparkles under my office lights. The rolling Azurite surfaces are accented by round nodules of
green Malachite which appear as micro-crystalline balls and smooth, reflective balls. Overall,
this is a specimen that is quite 3-dimensional with a good number of recesses. It's in excellent
condition with no problems to speak of and would make a great display piece in any collection.
From the Apex Mine, Jarvis Peak, Tutsagubet District, Beaver Dam Mts, Washington Co., Utah.
Measures 8.6 cm by 13.6 cm by 8.5 cm in total size.

Tucson2011-199GalenaCalciteSphaleriteKansas84mm.jpg (183827 bytes)

MIN#EXCEPTIONAL-87 NEW!

Textbook perfect combination of Galena, Sphalerite, and Calcite on Chert matrix!
This specimen could be pictured in a mineralogy book! The three crystal habits are so
perfect for the minerals featured and the way they are all sitting there together on the
same matrix is amazing. The Galenas are cubes, the Calcite is scalenohedral and doubly
terminated, and the Sphalerite is tetrahedral. In excellent condition with no visible contacts!
This specimen was in my personal cabinet for years and I'm pleased to offer it here.

MIN#EXCEPTIONAL-88 NEW!

Exceptional specimen of Native Silver crystals in cluster atop small amounts of Native Copper!
Very well crystallized specimen, displaying numerous well formed crystals of Native Silver branching our
from the base and climbing upwards atop one another. All are terminated with rounded terminations and
the surfaces are highly lustrous with a light greyish patina. The look of this specimen reminds me somewhat
of the spoked Cerussite clusters and is the second Native Silver I've offered on the website with that structure.
From the Kearsarge Mine, Kearsarge, Houghton County, Michigan.

MIN#EXCEPTIONAL-89 NEW!

Very fine example featuring numerous Boleite cubes on hardened matrix!
There are literally dozens of these lustrous blue crystals, with the largest cubes measuring around .6 cm
in size. All are stable on the matrix and there is no damage to speak of except for trivial bumps. The cubes
are also mostly clean with very little matrix attachment. The corners glow under lighting. In excellent condition.

MIN#EXCEPTIONAL-90 NEW!

Gorgeous large cabinet display specimen featuring a deep Golden Calcite crystal, doubly terminated, on Calcite covered matrix!
Easily the finest specimen from the Cumberland Mine that I've seen in a long time. The Calcite itself measures nearly 12 cm in
size and is doubly terminated at both ends with a deep, deep, golden gemminess which allows light to easily pass through and
make the crystal GLOW!! The large Calcite sits centered atop a matrix which is studded, top to bottom, with small golden Calcites.
I know how fussy Calcite collectors can be but let me assure you, this crystal is nearly pristine with full tips and superb surface luster.

Cumberland Mine, Central Tennessee Ba-F-Pb-Zn District, Smith County, Tennessee.

MIN#EXCEPTIONAL-91 NEW!

Classic specimen featuring thick Native Silver crystalline dendrites!
A superb, spinel-twinned Silver crystal, 4.6 cm in length, flares into a flag shape at its termination on this superb matrix miniature.
Several spinel twin crystals come off the main crystal at an angle, imparting a "herringbone" effect. This Silver is definitely competition
quality and stands among the top quality of specimens in its size class for Batopilas with a unique style. Note that this is NOT from the
more modern finds of the 1980s because those were much thinner and fragile. This older, more robust style came out in several finds
dating back to near 1910, though it is impossible to say from which one this came now. A very impressive, lustrous, and sturdy miniature.
From the New Nevada Mine, Batopilas, Andres del Rio District, Mun. de Batopilas, Chihuahua, Mexico.
Measures 4.5 cm by 2.5 cm by 2.1 cm in total size.

the bottom where it terminated against a matrix host. Very glassy and lustrous!

Tucson2014-293AcanthiteRayasMineMexico54mm.jpg (228309 bytes)

MIN#EXCEPTIONAL-93 NEW!

Superb cluster of Acanthite crystals with Pyrite on Calcite matrix!
Sharp crystals and an intense luster highlight this very aesthetic cluster. The Acanthite
crystals are all positioned vertically atop the Calcite which adds to the visual impact. The
largest crystal measures just shy of 2 cm in length. Some of the Acanthites display a slight
hoppering resulting from their quick transition from the higher temperature Argentite.
The specimen is in excellent condition with a back side stabilization along the right edge
to add structural support to the crystals in the area. The matrix is very well trimmed.
From the San Juan de Rayas Mine, Guanajuato, Mun. de Guanajuato, Guanajuato, Mexico.
Measures 5.4 cm by 4.2 cm by 2.9 cm in total size.

MIN#EXCEPTIONAL-94 NEW!

Rare specimen of Pyromorphite with Wulfenite and Calcite crystals from Mexico!
This specimen dates back to the 1880's-1890's and was once in the collection of the U. S. National Museum.
The original museum label that accompanies the specimen is stamped with the date of Oct. 10, 1927 but dates
prior to 1911 due to the inclusion of Division of Mineralogy on the label. After 1911, this name was changed.
The specimen is in excellent condition with no visible scuffs or contacts on the greenish-yellow Pyromorphite.
Mindat.org only shows one photograph of Mapimi Pyromorphite so it is quite rare. This is the only one I've seen.
From Mapimí, Mun. de Mapimí, Durango, Mexico.
Measures 9.7 cm by 6.8 cm by 5.4 cm in total size.

MIN#EXCEPTIONAL-95 NEW!

Brilliant crystal cluster of frosted tipped gem Calcite crystals!
This is a stunning work of natural art with its transparent, lead-crystal like Calcites and flat, frosted terminations.
Looking at the specimen, one is reminded of a chandelier, and when rotated under a light source, the crystals reflect
light in nearly the same way. For what this specimen lacks in color, it makes up for in brilliance! In excellent condition.

Tucson2011-255AcanthitePolybasiteReyesMexico5cm.jpg (259357 bytes)

MIN#EXCEPTIONAL-96 NEW!

Amazing specimen featuring lustrous Acanthite crystals sitting atop Polybasite!
Admittedly, I'm a Silver specimen fanatic and I go crazy when I see incredible combination pieces
like this one, but even non-Silver collectors can appreciate a specimen of this calibre! The pristine
Acanthites xls (largest measures 1.4 cm in size) sit perfectly atop very sharp blades of Polybasite
which are in turn, accented by a peppering of golden-iridescent Pyrite crystals. The Polybasite also
appears to be slightly coated by additional micro-Acanthites. I've never seen a specimen quite like
this one and the contrasting habits of both Silver Sulfides is what caught my attention. The largest
Polybasite is nearly 2 cm in width so it pretty hard not to notice! All crystals are sharp and distinct.
From the Reyes Mine, Guanajuato, Mun. de Guanajuato, Guanajuato, Mexico.
Measures 4.9 cm by 3.9 by 3.5 cm in total size.

MIN#EXCEPTIONAL-97 NEW!

Gorgeous specimen displaying a large vertical golden Calcite atop zoned Fluorite!
This is a wonderful large cabinet sized display piece featuring two glowing and semi-gemmy golden
Calcites atop a matrix of slightly etched and zoned bluish-purple Fluorite. The largest Calcite measures
10.5 cm in size and is perfectly doubly terminated. The smaller Calcite to its left lays horizontally across the
matrix. Both have very lustrous and glassy crystal faces. In excellent condition with no visual detractions.
From the Denton mine, Harris Creek Sub-District, Hardin County, Illinois.
Measures 18 cm by 13.4 cm by 8.2 cm in total size.

MIN#EXCEPTIONAL-98 NEW!

Fine crystals of yellowish-orange Pyromorphite on Barite matrix!
Good Pyromorphites from Les Farges are becoming very difficult to find these days. This one
has a less common color, best described as yellowish or greenish-orange, with sharp crystals
and minimal contacts, mostly on the smaller less important crystals. There is one missing
crystal just beneath the largest crystal in the center but it is well hidden in the recesses.
The Pyromorphite has very good luster and almost complete covered the Barite matrix.

Denver2016-73StibniteManhattanDistrictNevada95mm.jpg (389112 bytes)

MIN#EXCEPTIONAL-99 NEW!

Exceptional plate of freestanding Stibnite crystals on matrix from a classic Nevada locality!
Easily one of the best examples of Stibnite from the old mining town of Manhattan, Nevada, this
specimen is unusually complete and free of contacting. Stibnite specimens from this locality are
so often found smashed and broken but most of these crystals are complete and terminated.
The incomplete crystal tips are well hidden among those which are pristine and the luster is
excellent throughout. This is a well balanced, very well trimmed plate with a great provenance.

MIN#EXCEPTIONAL-100 NEW!

Really neat specimen featuring several Prehnite "fingers" pseudo. after Anhydrite!
Truth be known, all of these fingers are hollow casts but the way the horizontal crystal exposes
its interior next to the verticle crystals is not only unique but it's also very asthetic and dramatic!
The structure of the original Anhydrite crystals is still recognizable but is now displayed with light
green, lustrous surfaces. A very sturdy specimen that would look wonderful in any collection.
From the Lower New Street Quarry, Paterson, Passaic Co., New Jersey.
