MIN#Denver2017-1 NEW!

Exceptional and Museum Calibre specimen of crystalline Native Gold on white Quartz!
This incredible cabinet sized specimen of crystalline Native Gold on Quartz is the finest Gold I've ever offered
on the website in our over twenty years of business. Is is completely crystalline from top to bottom, front and back.
The crystals are sharp and distinct with an intense luster that makes the specimen pop out against the white Quartz.
It rises upwards nearly 13 cm and features elongated crystals measuring up to 3 cm in size! The specimen is easily
displayable from both sides and would make an exceptional centerpiece for the finest collections. If you're looking
for a MAJOR Native Gold of the richest color with dazzling brilliance throughout, then this is the specimen for you.
From the Eagle's Nest Mine, Sage Hill, Michigan Bluff District (Michigan Bluff deposit), Placer Co., California.

MIN#Denver2017-2 NEW!

Cherry red rhombs of Rhodochrosite set atop dark matrix!
This specimen makes me think of the Sweet Home but it is actually from Peru. The rhombs will fool you
somewhat since most Peruvian Rhodo specimens feature scalenohedrons. The color is a very rich and
slightly translucent cherry-red with a warm internal glow that you would expect in a fine Rhodochrosite
from the Sweet Home. Fortunately, this specimen costs just a fraction of the price. In excellent condition.
From the Uchucchacua Mine, Oyon Province, Lima Department, Peru.
Measures 5.9 cm by 4 cm by 4 cm in total size.

Exceptional specimen featuring standing blades of iridescent Covellite on Quartz and Pyrite matrix!
I rarely find Butte Covellites of this quality and those that I do find are usually not very iridescent.
This specimen is both! The blades are freestanding and super shiny-lustrous. The color is very iridescent
with brilliant flashes of red, purple, and blue. The blades are in excellent condition and protected inside
a concave matrix vug of Quartz and Pyrite. If you are looking for a top quality Covellite, this is the one!

Large, brilliant yellow Calcite sitting atop smaller yellow Calcite crystals!
This York, Pennsylvania Calcite is an exceptional specimen from an old classic American locality that I don't see
as often at the shows as in years past. The main Calcite crystal is large and complete on all sides with a strong glassy
luster over smooth surfaces. It's well centered on the Calcite covered matrix and free of any detractions or blemishes.

Tremendous plate featuring brilliant crystals of reddish-orange Vanadinite on matrix!
Brilliant, lustrous, and pristine are the the three words that describe these large Vanadinite crystals! The crystals are
very distinct and contacts are nearly impossible to fine. The largest Vanadinite crystal measures to nearly 2 cm in size
but most are larger than 1 cm and there are dozens and dozens of them on this large plate.
From the 2009 find, noted
for its thick, robust crystals. In excellent condition with few contacts, this plate makes an exceptional centerpiece.

MIN#Denver2017-6 NEW!

Super aesthetic combination of Native Silver with Acanthite crystals and Siderite!
Frieberg Silvers are among the most attractive and sought-after Silvers in existence, and this attractive miniature well illustrates the reasons.
This is an elegant piece! The pair of Silver wires curve up beautifully from their attachment at the base, and the wires are coated by Acanthite crystals.
For additional color accent, the wires have a partial microcrystalline coating of tan Siderite and white Calcite. Overall, this is an aesthetic and very fine
combination piece that would grace any mineral collection. With its unique form, it is one of the finest, most unique Freiberg minatures that I have seen.
From the Freiberg District, Erzgebirge, Saxony, Germany.
Measures 4.4 cm by 3.3 cm by 1.3 cm in total size.

MIN#Denver2017-10 NEW!

Amazing specimen featuring gemmy Golden Calcite crystals inside a fossilized clam shell (Mercenaria Permagna) ON MATRIX!
These specimens formed from old clam shells which were buried many years ago, allowing the Calcium to transform and grow into
Calcite crystals over time. As the Calcite crystals grew, the Calcium was taken from the outer shell which caused it to dissolve
as the transformation took place. Specimens of this quality with complete shells are very rare. Matrix specimens like this one
are unbelievably rare. Actually, this is the only open clam shell specimen that I've ever seen on matrix from this locality.
From Rucks Pit, Fort Drum, Okeechobee County, Florida. (From the Pliocene-Pleistocene Epochs).
Measures 7.8 cm by 11 cm by 6.6 cm in total size.

MIN#Denver2017-11 NEW!

Gorgeous and unusually rich example of bi-colored Beryl (Aqua-Morganite)!
A sharp, single crystal specimen of Beryl showing gemmy blue Aquamarine atop rich Morganite, which is a color pattern not often seen.
This specimen, from a small find in early 2014, is a superb miniature. The blue zone is over 1 cm thick, and is no "thin line" of color from one angle
as can sometimes happen. This is simply a bold and dramatic color! The pink body on this piece is especially rich. The crystal is nearly complete all
around, with only some matrix contact irregularity on the back. The termination is a perfect hexagonal right out of a textbook. Stunningly beautiful!

translucent emerald green Fluorite octahedron, measuring 3 cm on an edge and 4 cm across the tips. The large crystal is partially encased
by a sparkling druse of dark Quartz alternating with white Quartz, for contrast. Like others in this find, it is unique in its own, even amongst
the many specimens from the big find of several years ago. This specimen is complete all around and has depth and superb richness of color.

a concave structure, with glassy surfaced Fluorite cubes above and along the sides. These lustrous cubes are
well zoned with a bluish-lavender zoning and glow with a vibrant golden coloration with just a hint of orange.
Framing the plate along the left side and upper edge are numerous bundles of wheat sheaf-like Calcite crystals.
In excellent condition with contacting limited to the outer trimming edges. A unique and colorful Fluorite plate.

Super shiny botryoidal surfaces of reddish-brown Hematite from the old mines in Michigan!
This fine specimen is an excellent representative of Michigan Hematite which I rarely see in the marketplace
and if I do, they usually come from older collections. This specimen is from the Tracy Mine and was probably
mined in the 1960's or 1970's. Oddly enough, I just noticed that the Tracy Mine is currently up for sale if anyone is
interested at the very reasonable asking price of $250k. This piece is in great shape with clean, contact free surfaces.

Gorgeous cabinet sized cluster of Quartz var. Amethyst crystals!
This is a classic specimen of South Carolina Amethyst. The crystals are large and glassy with
a grape juice coloration. There are no real detractions to speak of with this fine specimen - only
trivial micro-bumps here and there. This is one of the finest specimens of this size range I've seen.
It is also completely covered by crystals on all sides and could be displayed on a rotating base.

Gorgeous plate of golden Fluorite cubes on matrix from the old Silver Mining District of Germany!
A large matrix piece with a very rich coverage of fluorite, from this small and important find in the old Silver district.
It showcases large and colorful crystals to nearly 2 cm. Contacted around the edges, only. This is, I am told, the largest
plate that was available in such excellent condition. A very impressive German Fluorite and a must for a Fluorite collection.

Acanthite crystalline balls along the bottom, just below the leaf. A great looking Silver from a lesser seen and rarer Cobalt mine.

Gemmy crystal of Golden Calcite with scattered Barite cluster perched atop matrix!
Completely transparent with a glowing gemmy interior, this Calcite makes it obvious why
the Elmwood Mine's Jewel Pocket is so highly prized by collectors worldwide. I can easily
read print through this crystal, and the termination is pure glass with a nearly pristine tip.
Only a couple of tiny chips keep it from being completely pristine and you'll need a 16x loupe
to see them. They are invisible to the naked eye. The Calcite measures nearly 7 cm in length.
Small clusters of white Barite can be seen scattered about the matrix and there is a smaller
Calcite perched atop the upper back edge of the specimen. This could be easily be trimmed.
