Gorgeous combination of cherry-red Rhodochrosite rhombs with purple Fluorite, Quartz, and Sulfides!
This is a specimen that pops in a display case and has the eye catching ability of a very expensive Sweet Home
Rhodo at a much more affordable price. The rhombs are deeply colored with a glowing cherry-red coloration. They
measure to 5 cm in size and are bordered by deep purple Fluorites to the left and dark matrix Sulfides and Quartz
to the right. The visual impact is stunning. This specimen holds it own against Rhodochrosites in the high five figure
price range but is much more affordable because of some minor contacting along the back edges and matrix contacting
on the back side of the Rhodo rhombs. This is invisible from the front presentation and is completely natural and of
little importance to the overall beauty of this piece in my opinion. Opportunity knocks with this breathtaking specimen!
From Nate's Pocket, Sweet Home Mine, Alma, Colorado.
Measures 7.5 cm by 7.8 cm by 4.7 cm in total size.

Superbly crystalline Native Gold on Quartz!
At first glance, the large trigon crystals along the top jump out at you but when you take
a closer look at this gleaming specimen, you see that it is completely crystalline from top
to bottom! Trigons, flattened crystals, dendritics, and dodecahedrons form the body of this
incredibly lustrous and flashy Gold specimen. The center portion is so crystalline dendritic
that it takes on the appearance of woven fabric! The Quartz is nearly all white and is perfectly
proportional to the Native Gold. California Golds of this quailty are becoming extremely difficult to
find and this one represents a wonderful opportunity. This specimen represents a unique opportunity!
From the Eagle's Nest Mine, Placer County, California.
Measures 5.7 cm by 3.7 cm by 2.4 cm in total size.

MIN#Denver2017-83 NEW!

Exceptional and very impressive specimen of Native Silver with Acanthite in Calcite matrix!
I acquired this specimen from a private collection in Cobalt and it went immediately into my personal cabinet.
It's the finest Cobalt Silver specimen I've seen and is a true centerpiece. Brilliant, leafy, dendritic Native Silver
rises upwards atop the various seams of Silver and gray Acanthite running through and atop the matrix below.
The appearance of the Native Silver rising atop the matrix and the contrasting seam throughout the Calcite and
greenish matrix is incredible and super aesthetic. I've searched for classic specimen of Silver from the world
famous Cobalt Mining District for many years and specimens of this calibre are extremely rare. A true prize!
From the Beaver Mine, Cobalt Area, Cobalt-Gowganda Region, Timiskaming District, Ontario, Canada.
Measures 14.2 cm by 14.3 cm by 8.3 cm in total size.

MIN#Denver2017-84 NEW!

Gorgeous specimen featuring large, multi-colored Tourmaline crystals perched aside Smoky Quartz and Feldspar!
This large 7 cm Tourmaline crystal is a visual delight with its layering of colors, perfect termination, and glassy-
lustrous surfaces! The gemmy interiors display flashes of reddish-pink which change over grassy-green and
chartreuse before capping out with a hint of reddish-pink again. Luster flows up and down the surface striations
and the main Elbaite crystal is accompanied along the right side by a smaller crystal of similar coloration. This
crystal is quite unique in that it shows evidence of a natural shift in formation, possibly a breakage which rehealed
in the pocket and continued upwards to termination. I love specimens like this which show the forces of their
geological environment through the formation of their crystals. Smaller, very gemmy Tourmalines can be seen
to the right of this crystal, atop the Feldspar matrix. All display full terminations and a strong internal brilliance.

Major Rarity! Brilliant yellow Diamond set atop matrix from Sierra Leone!
This is something you almost never see, a matrix Diamond from Sierra Leone. The crystal is
bright and gleaming with a lovely golden-yellow brilliance. The close up photo above shows how
sharp the natural growth is with well defined, glassy faces. The crystal measures .5 cm in size and
is in the 1.2 - 1.3 carat range. Most Diamond crystals from this locality are found off matrix so
when a legitimate, quality  matrix specimen comes to market, it usually doesn't last very long.
From the Northern Province, Sierra Leone.
Measures 4.6 cm by 3.5 cm by 2.2 cm in size.

Tremendous specimen of super lustrous blue Anhydrite crystals in cluster with Sphalerite!
Quality cabinet sized clusters of Anhydrite have become very difficult to find over the past decade and I can
honestly say this is the first specimen that has impressed me in a very long time. Naica is known to have produced
some outstanding Anhydrite specimens and this is an excellent example of translucent crystals with pretty icy-blue color.
The surfaces are radiant with a rolling luster and there are no contacts worth mentioning. Very well balanced and aesthetic.

MIN#Denver2017-87 NEW!

Beautiful example from a recent find of Quartz ps after Wulfenite crystals!
This specimen still displays some of the yellowish- orange coloration of the blocky Wulfenite crystals and this contrasts
beautifully with the sparkling drusy covered surfaces and white banding of the Quartz. Beneath the Quartz, some of the
interiors still reflect their original Wulfenite so technically, the specimen is a partial pseudomorph. I like it better that way
because it's more interesting. In excellent condition with few contacts and a dazzling crystal form atop the concave structure.
From the Kimbanga prospects (Kimbanga mine), Kimbedi, Mindouli District, Pool Department, Republic of Congo (Brazzaville).

Intensely lustrous and dazzling specimen of pearly-silver Smithsonite from Greece!
What an amazing specimen this is with its highly sculptural form and blinding, sparkling, rolling botryoidal
surfaces! This old classic is from the mines in Laurium and undoubtedly dates back to the 1800's or earlier.
It is the most impressive Smithsonite I can recall seeing from there in quite a number of years and it's in
excellent condition with nearly pristine surfaces covering its cabinet sized structure. Exceptional in every way!

Exceptional new find featuring Azurite with Malachite stalactites on Azurite with Malachite matrix!
This incredible large cabinet sized specimen is from a small and obscure find at Sha Wan La Ji, Wan Xiang,
a Laos locale that is not yet listed in mindat.org! The stalactites are probably hollow, consisting of Goethite
or Limonite which has been overgrown by velvety Malachite and lustrous micro-crystalline. lustrous Azurite.
I have only seen a few of these rare pieces and this is BY FAR the largest and most spectacular of all!  The
stalactite tips are complete and undamaged and the entire specimen is pretty much pristine. A true centerpiece.

MIN#Denver2017-90 NEW!

Exceptional combination of hot pink Fluorite crystals with lavender Calcites and Quartz on Feldspar!
Easily one of the finest Alpine Fluorite combos I've seen in years. The large pyramidal reddish-pink Fluorite
sitting atop the far left side measures 4 cm in size! The color glows through transparent-glassy surfaces and the
crystal is complete and pristine on all sides. A smaller Fluorite of the same color can be seen nestled among the
lavender Calcite crystal atop the right portion of the sparkling and quite flashy white matrix which appears to be
accented by Adularia crystals in addition to small Quartz needles. The Calcite crystals measure to 3.8 cm in size
and like the Fluorites, are blemish and contact free. One of my favorite finds from the show with superb aesthetics.
From Zinggenstöcke, Oberaar Lake area, Grimsel area, Hasli Valley, Bern, Switzerland.

Glassy crystals of emerald-green Dioptase on white Calcite covered matrix!
One of the prettiest Dioptase specimens from the show. Not many plates come prettier than brilliant green
Dioptase on white Calcite specimens. These Dioptase crystals measure to 1.7 cm in size and are in excellent
condition with superb lustrous surfaces. They sit atop the stark white Calcite with good isolation and the matrix
is very well trimmed. Any contacts are minor and along the outer trimming edge. This plate is simply outstanding!

Lovely specimen featuring rhombs of cherry-red Rhodochrosite with Pyrite and Quartz on Tetrahedrite matrix!
This is a beautiful miniature sized Sweet Home Rhodo specimen which has a lot of mineral bang for its very
reasonable price. The main rhomb is completely transparent with gemmy interiors of glowing red. It measures
1.5 cm in size and is accompanied by over half a dozen Rhodo rhombs of various size. The golden Pyrite
crystals are a nice touch and contrast well with the lustrous Tetrahedrite and white Quartz crystals. This is
one of the better Rhodo miniatures I've seen in a while with a quality rhomb and no detractions to speak of.

MIN#Denver2017-93 NEW!

Exceptional and quite heavy nugget of Native Silver with Cobalt bloom coating!
These reddish Erythrite covered specimens were once commonplace in the Cobalt Mining District and are characteristic
of the area's name being that the mineral is an Arsenate of Cobalt. Rarely are they encountered in today's marketplace
however, because most specimens are cleaned of their Cobalt bloom coloration and the pink layer is removed. I think
this process is a true shame but it does make specimens like this one extraordinarily rare due to their originality. This
heavy nugget of Native Silver is completely solid and the Erythrite is so well preserved that it shows actual crystallization.
From the Cobalt area, Cobalt-Gowganda region, Timiskaming District, Ontario, Canada.
Measures 8.2 cm by 11 cm by 5 cm in total size.

Amazing new find of Beryl var. Emerald on Biotite matrix from Ethiopia!
A very small collection of incredibly fine Emerald specimens from Ethiopia appeared at Tucson this year
and I had the ability to cherry-pick the grouping for the best of the best specimens. The color of these Emeralds
is superior to anything I've seen from Africa and is better than Emeralds from Nigeria and Zambia in my opinion.
They are colored by Chromium and have an inner brilliance and color intensity very similar to what one sees in
Colombian Emeralds. The above specimen was the second largest matrix specimen of which there were less than
half a dozen as most are removed from their matrix by the local miners. It is fully terminated and full of glowing
gemminess beneath glassy-lustrous surfaces. The matrix is Biotite covered Feldspar and there is no damage.
The horizontal Emerald crystal measures 2.7 cm in length by 2 cm in width! It is actually doubly terminated with
a smaller termination peeking out from the Biotite matrix on the bottom side. In excellent condition and very nice!
From Kenticha, Kenticha Pegmatite Field, Seba Boru District, Sidamo-Borana Province, Ethiopia.
