MIN#TUCSON2020-101 Sold!

Super aesthetic display of Native Silver wires with Acanthite and Sphalerite rising high above Quartz matrix!
This incredible matrix Silver is from China which makes it very rare as most Chinese Silvers do not have matrix.
 This cabinet sized specimen has all the visual presence of a much larger Silver, but at a much lower price. The wires
display a lovely antiquish patina and a good deal of surface luster. They rise up organically from a sparkling Quartz
matrix, twisting and curling as they stretch upwards. Just below the grayish Acanthite are several yellowish Sphalerite
crystals which is an amazing thing to see. Also, the Quartz matrix has a small, Silver lined vug just to the left of the wires.
Locality: Hongda Mine, Lingqiu Co., Datong Prefecture, Shanxi Province, China.
Measures 9.3 cm by 5.8 cm by 4 cm in total size.
Comes with a custom made, labeled display base
Price $21,500

MIN#TUCSON2020-102 NEW!

Absolutely stunning arrangement of elongated Aquamarine crystals with Schorl Tourmaline on Albite!
This lovely specimen displays not one, but two elongated Aquamarine "pencil" crystals, rising up from a
bed of smaller Aquamarines and shiny black Schorl Tourmalines! They exhibit a deep blue color through
gemmy interiors, glassy faces, and topped by textbook terminations. The smaller crystal was placed back
on the matrix so it is technically repaired but I can't see it and you would never know it if I hadn't mentioned
it to you. It does however keep this from being a 45k specimen and makes the piece an incredible bargain
at its asking price. The shorter Aquamarines in the middle are also terminated with complex, matrix influenced
terminations which display numerous faces at various angles. This is one of the most impressive Aquamarines
I've seen recently from Shigar and It would make a beautiful centerpiece in any collection. In excellent condition.
Locality: Shigar Valley, Skardu District, Baltistan, Gilgit-Baltistan, Northern Areas of Pakistan.
Measures: 12.8 cm by 8.2 cm by 7 cm in in total size.
Price $28,500

MIN#TUCSON2020-103 NEW!

Dazzling specimen of crystalline Native Gold rising up from white Quartz matrix!
This is easily one of the finest, most graceful and aesthetic Golds I've ever seen or offered! It is
totally crystalline in structure with dendrites, octahedrons, spinels, and more, all situated around a
central towering spire of pure brilliance. Near the top, the specimen becomes very arborescent and
takes on the appearance of a golden castle atop a mountain. The structure is an amazing sight under
magnification and has enough going on to keep someone occupied for quite some time. The surfaces
are super bright with a brilliant luster and flash from top the bottom. The specimen could actually be
displayed from either side as both are attractive with an equal amount of white Quartz at the base.
Locality: Eagle's Nest Mine, Placer County, California.
Measures: 10 cm by 5.7 cm by 5.2 cm in total size.

MIN#TUCSON2020-104 Sold!

Gorgeous elongated specimen of Horn Rhodochrosite!
Polished on the top side to fully display the rich color and internal rings, the color and patterning is stunning.
This is one of the few Rhodochrosite horn specimens that I've seen recently which wasn't cut into a thin slab.
It has the external rind all the way around and was left natural on the bottom for contrast. In excellent shape.
Locality: Capillitas Mine, Andalgala, Catamarca, Argentina.
Measures: 4 cm by 4.8 cm by 4.7 cm in total size.

MIN#TUCSON2020-105 Sold!

Exceptional cabinet sized Native Wire Silver on Silver and Acanthite matrix!
This specimen has tremendous eye appeal and artistic form. It has the presence of a much more expensive
Native Silver from the famous Freiberg Mining District but offers it all in a much more affordable price range.
The wires are thicker at the base, measuring 1.5 cm in width. They rise upwards to a height of nearly 12 cm and twist
and turn in a way that is so sculptural and dramatic that it's impossible not to be impressed. The wires are of varying
height and there are many curls and shepherd's hooks as they terminate. Clean and lustrous with a light dusting of
Acanthite drusy between the striations, the antique patina is absolutely gorgeous. Can be displayed from either side.
Locality: Himmelsfurst Mine, Freiberg District, Erzgebirge, Saxony, Germany.
Measures: 13.2 cm by 5.7 cm by 3.2 cm in total size.

Amazing pocket vug featuring fine dendrites of Native Copper on Calcite crystals!
This is literally a Copper-Calcite geode. It is half of a Calcite lined vug inside a Hematite matrix,
covered from one end to the other by Native Copper dendrites! The visual contrast is stunning with
patinaed Copper dendrites strewn across the small white Calcite crystals. An old classic from the 1880's.

MIN#TUCSON2020-109 NEW!

Incredible specimen featuring thick Aquamarine crystals on Muscovite and Albite!
The Aquamarines are perfectly terminated and jut out in all directions atop the silvery bladed
Muscovite covered matrix! This is a tremendous Aquamarine specimen from a famous locale
that just isn't producing the same quality that it once did. This specimen probably came to market
back around 2002 or 2003 and its aesthetical qualities are excellent. The crystals are terminated
with flat tips and only the occasional modification. The faces are glassy with transparent interiors
throughout with better than average color. Contacts are few and invisible among the dozens of crystals.

Elegant specimen featuring gemmy green Tourmalines with blue capped terminations on Quartz!
This is an amazing cluster, featuring half a dozen Tourmalines, all of them super glassy and beautifully
striated with a rolling luster. Five of the Tourmalines display a vivid blue cap termination above the
gemmy to translucent green lengths. The sixth Tourmaline is a rehealed termination which displays the
faint beginnings of a blue cap which did not fully develop. The cluster of Tourmalines sit atop the front
side of a Quartz crystal which serves as the host matrix.
From Barra do Salinas, Coronel Murta, Minas Gerais, Brazil.

FinRare combination of Galena crystals with Siegenite!
The Galena octahedrons and rare Siegenite crystals sit along side one another with lustrous Galena
cubes. Siegenite is a rare Nickel Cobalt Sulfide. This is by far, the largest plate of this mineral that I've
ever offered and it is richly covered by the slightly golden, highly lustrous crystals. A great display piece.

Fascinating specimen featuring sculptural Azurite nodules on Arkose matrix!

under direct lighting. Fluorite crystals can be seen to the top left and lower right near the edges.
