a gorgeous internal rainbow! The Calcites are highly lustrous with transparent interiors and
are framed by equally lustrous Stilbite crystals, many of which are doubly terminated. The
display is very aesthetic and the combination is stunning. In excellent condition with few
contacts and no damage. The specimen can also displayed in a myriad of ways, all attractive.

MIN#Denver2015-62 NEW!

Emerald-green crystals of Dioptase covering a white Calcite crystal matrix!
This is one of my favorite combinations from the mineral world and I know I share this
opinion with many other collectors. This specimen offers an abundance of glassy green
Dioptase crystals, measuring up to 1.3 cm in size, and displays an incredible amount of
flash and internal luminescence. Rotating the specimen in my hand makes the crystals
sparkle wildly as each smooth face reflects the light with an incredible intensity. It is also
very evident that this specimen is in excellent condition with very few contacts and well
tucked trimming edges. The white Calcite crystal surface beneath the Dioptase peaks out
along both the left and right sides and displays a good translucence with no visible contacts.
From the Tsumeb Mine, Tsumeb, Otjikoto Region (Oshikoto), Namibia.
Measures 6.6 cm by 4 cm by 2.7 cm in total size.

Super combination plate of Sphalerite crystals with brown Siderite on Pyrite crystals and Calcite!

measure to over 2 cm in size and are a highly lustrous black or very dark brown. The Siderite which
is present between the Sphalerite is a yellowish-brown. The Pyrite displays as lustrous golden cubes
and the entire back side of the specimen is covered with graying Calcite blades. In excellent condition.

MIN#Denver2015-68 NEW!

Sparkling specimen of blue Chrysocolla covered by Quartz with Quartz arches!
This is beautiful specimen and the first I've seen with Quartz arches which stretch across the
matrix vug from one side to the other, forming a slightly curved bridge of micro-Quartz crystals.

micro-crystalline Quartz. Very flashy with an intense brilliant sparkle in even the faintest lighting.

Very pretty combination of zoned Fluorite with golden Calcite and Sphalerite on matrix!
This is an unusual specimen but one that is covered with lots of great looking crystals.
The Fluorite cubes are bluish-lavender with raspberry zoning. The Calcites are a light
golden color and most are doubly terminated. In the background are micro-crystals of

MIN#Denver2015-73 Sold!

Exceptional specimen of Native Silver crystals, one atop the other, atop a Native Silver base!
This is an old classic specimen, dating back to the 1880's, and it comes from the same collection
my "Pine Tree on Copper" specimen came from. Both were preserved by the same miner over
130 years ago and remained in his family before being sold just recently. This specimen is pure
Silver with no Copper present, and is formed from numerous crystals measuring to 2 cm in size.
Even the base appears to be a crystal or crystals that were flattened somewhat by surrounding
matrix which has long since been removed. The specimen is highly lustrous and exhibits a gentle
antique greyish-golden patina. It's very sculptural with a beautiful form and even includes a natural
opening formed by touching crystals along the top left. This was easily one of the most impressive
Native Silvers at the show and is completely original. It also offers a lot of size for a reasonable price.
From the Calumet & Hecla Mine, Calumet, Calumet Township, Houghton Co., Michigan.
Measures 9.7 cm by 3.6 cm by 2.1 cm in total size.

Lovely golden Calcite cluster on matrix!
This is a beautiful, well balanced cluster of three perfect, gemmy Calcites. The Calcites are
all terminated with glassy surfaces and a strong rolling luster which further highlights the golden
interiors. The matrix is the typical Limestone and one of the crystals is doubly terminated on the back.

Large cabinet sized specimen featuring two impressive crystals of Selenite on matrix!

Large, golden, barrel-shaped Calcite crystals with Marcasite and Fluorite on matrix!
Amber colored Calcites, highly glassy and very lustrous with the largest doubly terminated
crystal on the left measuring 8.5 cm in size. There appears to be a darker phantom inside each
Calcite, possibly an earlier Calcite crystal that was later overgrowth. In good condition with some
contacting here and there but nothing serious. The smaller Calcite has a bit of Fluorite at the bottom.

MIN#Denver2015-77 NEW!

Light green cluster of Fluorite cubes from a classic Austrian Fluorite locality!
A great looking specimen that is glassy Fluorite all the way around, on all sides. The cubes vary
in size but all display a light green coloration through gemmy interiors and lustrous surfaces. The
color actually gets deeper when the specimen is exposed to direct lighting. In great shape overall,
with just some minor contacts scattered about but nothing that really detracts from this classic piece.

It has been mined for hundreds of years and was one of the main Silver mines for the
Spanish beginning in the 1530's. This specimen displays a curling Silver wire that rises
over 3 cm atop the Acanthite crystal matrix. The wire is firmly attached and sturdy.

MIN#Denver2015-79 NEW!

Historical and very rare specimen of Native Gold with Silver Sulfides on matrix from Nevada!
This cabinet sized plate is an amazing example of American and Nevada mining history. It's from
the old mining district of Tonopah, Nevada which was the home to a huge Silver mining boom in the
early 1900's. While Silver was the main ore discovered in Tonopah, there were also gold deposits
although most were a bit further south in Goldfield. This specimen displays a large Rhyolitic volcanic
plate, naturally seamed, into which flowed Native Gold. The Gold cooled to form micro-crystalline
clusters. The close up photos display the front and right edge of the specimen which is covered with
the brilliant precious metal. The Gold is mostly crystalline dendritic with some small trigons, leaves,
and mesh also present. Gray Silver Sulfide is also present in the matrix but the Gold is the main draw.
Specimens of this size with this much Gold coverage from Tonopah, Nevada are incredibly rare today.
Circa 1910 - From the Tonopah District, San Antonio Mts, Nye County, Nevada.
Measures 15.4 cm by 12.6 cm by 5.2 cm in total size.
