MIN#EXCEPTIONAL-101 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.

Denver2014-2AzuriteConceptionDelOroMexico138mm.jpg (386283 bytes)

MIN#EXCEPTIONAL-103 NEW!

Sharp, lustrous crystals of Azurite with Malachite on Calcite covered matrix!
This is a tremendous old time classic from Zacatecas. It was formally in the famed Romero Collection
before being donated to the University of Arizona Mineral Museum. With so much attention paid to the
Milpillas specimens these days, the old classic Azurites from Mexico are being somewhat overlooked
and this is definately one that should be taken notice of. The surface of this plate is covered from one
end to the other by dozens of glassy-lustrous Azurite crystals. The crystals measure to 1.4 cm in size
and average around 1 cm in size. They display chisel-tip terminations and many are doubly terminated.
Surrounding the dark blue Azurite crystals are transparent Calcites and a small cluster of Malachite
ps after Azurite crystals to the far right. They all sit atop a matrix covered with smaller Calcites and
the specimen is in excellent condition overall, with most contacts being limited to the trimming edge.
From Concepción del Oro, Mun. de Concepción del Oro, Zacatecas, Mexico.
Measures 9 cm by 14 cm by 4.8 cm in total size.

Very rare specimen featuring a Diamond crystal on Kimberlite matrix!
This is a perfectly formed 1 carat Diamond of top brilliance and color firmly attached to the host matrix.
Diamonds from the Pretoria District of South Africa are almost never found on matrix and very few were
preserved over the years. The Diamond crystal measures .7 cm in size with sharp, facet-like faces and a very
intense internal brilliance that becomes almost blinding when highlighted. A true rarity and a unique opportunity.

MIN#EXCEPTIONAL-106 NEW!

Lovely specimen featuring two Beryl var Aquamarine crystals crossing atop Albite with Apatite!
This is a true work of art. Both gemmy blue Aquamarines are doubly terminated, forming a Saint Andrew's
cross near the center. The right Aquamarine steps down below the cross but the form is perfect. Two pinkish
Apatite crystals measuring to 2.5 cm in size sit atop the specimen which is completely framed by bright white
crystals of Albite. The eye appeal and aesthetical qualities of this specimen are exceptional. No damage.

MIN#EXCEPTIONAL-107 NEW!

Gemmy green spiral clusters of Green Apophyllite on lustrous Stilbite crystals!
These popular "Well" Apophyllites have become very difficult to find in recent years
since most specimens have now disappeared into private collections and no new discoveries
have been made. This cabinet sized plate features two separate radial sprays, a "bow tie"
spray at upper left and a ball spray to the right. The Stilbite crystals cover the front and
climb over to backside of the volcanic matrix. In excellent condition with a great display.

Fine doubly terminated crystal of Beryl var. Aquamarine with Albite!
This beautiful Aqua specimen exhibits a misty-blue, almost cat's-eye appearance in the center portions
and caps off with a crystal clear termination. Upon closer inspection, it appears that a smaller, translucent
Aquamarine crystal was overgrown by a larger, more transparent crystal creating one heck of a phantom
up the crystal center and at the top! In excellent condition overall with great eye appeal and presence.

Tucson2013-301b2.jpg (572204 bytes)

MIN#EXCEPTIONAL-109 NEW!

Rare specimen of Native Silver with Safflorite and Amphibole Asbestos from Cobalt, Ontario!
This specimen is entirely composed of Native Silver leaves and dendrites, nestled between crystal
balls of Safflorite and sprays of Amphibole Asbestos. The Native Silver is lustrous with a slightly
golden patina while the Safflorite is steel gray to dark gray. This impressive specimen from the
historical Cobalt area is quite heavy and loaded with Silver all the way through the solid base.
The Amphibole Asbestos appears as tightly packed fibers and they sit atop the surface of both
minerals as well as filling the concave openings in the solid matrix. This is a superb example of
the richness of the Cobalt area, one of the richest strikes of Silver ever recorded. I wouldn't be
surprised if there was also some Nickeline or Skutterudite in this very rich mineral specimen.
From the Cobalt area, Cobalt-Gowganda region, Timiskaming District, Ontario, Canada.

Rare specimen of Native Gold with Pyrite crystals on Quartz from the Mother Lode!
Old time specimen featuring lustrous leaf Gold nestled between white crystal points! There
are Pyrite crystals scattered about and the leaf surfaces range from mirror-smooth to matted
in texture. I would date this specimen to the mid 1850's to as possibly as late as 1890. The old
label is brittle and in two pieces with the middle portion missing but the words Oro, quarzo, and
California are visible. Numerous Quartz crystals form the host matrix and some are terminated!

MIN#EXCEPTIONAL-111 NEW!

Very rare specimen featuring wires of Native Silver and Acanthite in a Quartz matrix vug!
This specimen is from the famous Silver Islet Mine which is now completely underwater. This is
a very impressive specimen and one of the best I've seen from the locale, displaying thick wires
of Native Silver which emerge from the matrix recess and push outwards with a couple rising atop
the matrix where they form a curling ram's horn. Scattered about the edges and atop the Quartz
matrix are dark gray Acanthite crystals. A historical specimen dating back to the 1870s -1880s
since the mine closed for good in 1884. Very lustrous with a beautiful antique patina atop the wires.

MIN#EXCEPTIONAL-112 NEW!

Impressive plate of Galena cubes with Pyrite set atop black Sphalerite matrix!
This is one of the finest large sized plates of Galena that I've seen from Creede. The sharpness of
the Galena cubes as well as their sheer number atop the matrix places the specimen above most of
what I've seen from this classic mining district. The cubes are reflective to lustrous and average around
1 cm or so with the largest measuring 2 cm in size. They are very well preserved with barely a contact
worth mentioning. Small golden Pyrite cubes are also present, interspersed between the Galena crystals.

This is one of the better Uvarovite specimens I've had the pleasure of offering on the website.
It's small cabinet in size and richly covered from left to right with lustrous green Uvarovite Garnets
in varying sizes. The largest of these measure 4 mm in size which is pretty large for the locality. All
are gemmy with bright, reflective surfaces. The only contacts of note are those along the trim edge.

MIN#EXCEPTIONAL-114 NEW!

UNIQUE! Museum plate featuring a huge Goethite ps after Siderite sitting atop Amazonite and Smoky Quartz!
I've never seen another specimen like this. The Goethite pseudomorph sits atop the plate of Amazonite, Smoky
Quartz, and Albite like a huge mountain range. While pseudomorphs of this variety are aometimes found at the
locality, very few ever come close to this size and magnitude. It's just amazing to see and a pseudo collector's
dream specimen. The plate has been repaired of course as almost all of these are but the work was done very
well and all the pieces were in the pocket. I mentioned this is a museum quality specimen and it actually is.
It was formally in the University of Michigan's Mineral Collection and is deserving of an advanced collection.

MIN#EXCEPTIONAL-115 NEW!

Superb combination plate featuring Beta Quartz crystals on green Datolite with Quartz accents!
This is a lovely large cabinet specimen and one that stood out in the same display case as the large Amethyst
plate in the earlier showroom. The plate is completely covered by glassy green Datolite crystals which range
from gemmy to translucent. These crystals are accented by small Quartz crystals which outline the edges and
fill the recesses between the Datolites. Sitting in the very center of this flashy plate is an impressive cluster
of Beta Quartz crystals, with the largest measuring 5 cm in size. Beta Quartz is a hexagonal bipyramidal form
of Quartz that occurs at high temperature. At room temperature it is actually Quartz ps. after Beta Quartz but
the unique crystal habit remains. There are a half dozen of these crystals in the center cluster. This is a very
fine plate and one of my favorites from the show. It is very well trimmed with few contacts. A true centerpiece.

Sweet specimen of Arsenian Pyromorphite crystals on matrix!
This is a wonderful miniature with no visible damage and enough sparkle and flash for several
specimens. The crystals are bright yellowish-orange and display a visible translucence. Upon
closer examination with a 16x loupe, I can see just how glassy the crystal faces are and most
of the Pyromorphite crystals display a pyramidal termination. The matrix is brown and cast-like/

Breathtaking specimen of bluish-lavender Fluorite cubes with Barite on Sphalerite!
This lovely specimen displays half a dozen transparent cubes of soft blue Fluorite, so clear
that you can see down to the matrix beneath. They are lustrous with a smooth flowing luster
which highlights every surface detail. The cubes are surrounded and partially covered along
the far left edge by snowy-white Barite crystals, making for one of the prettiest Illinois combos
in quite some time. In excellent condition with one incomplete crystal along the lower trim edge.

MIN#EXCEPTIONAL-120 NEW!

Exceptional large cabinet plate of Amethyst crystals on a unique looking brown matrix!
Believe it or not, it was the matrix that first attracted my attention when I came across this very
impressive large plate at the show. It looked like the cracked clay bed of a dry river bottom and it
was covered with a sparkling druse. I've not another another matrix like it from Piedra Parada and
the large Amethyst crystals that sit atop are absolutely perfect and pristine. They are fully terminated
with gemmy interiors and a glowing purple coloration. The largest crystal is doubly terminated and lays
horizontally to the matrix. It measures 5.5 cm in length. The other Amethyst crystals vary in size and rise
vertically atop the dazzling surface. This is one of my favorites from the show. It's a superb display piece.
