MIN#EXCEPTIONAL-22 NEW!

Exceptional!! Unique and stunning specimen of Native Silver dendrites rising up from a Calcite crystal!
This is a White Pine Silver and it is the finest example I've ever seen from this classic locality. To find
a matrix White Pine Silver is a rare thing. To find a matrix White Pine Silver with the crystalline Silver
dendritic structure rising up from a Calcite like a Kongsberg specimen is AMAZING to say the least!!
The dendritic crystalline structure rising up from the matrix is sharp and distinctive and covered with a
lovely antique patina over santiny lustrous surfaces. In excellent condition with exceptional eye appeal.

Very rare plate of blue to sea green-blue Fluorite crystals on matrix!
This is a rare specimen of bluish Fluorite from Switzerland and is the first I've offered from this

slight lavender coloration. The Fluorites are in excellent condition and featuring numerous, although
tiny inclusions of Bitumen which forms some really neat patterns beneath the surfaces. Some of

Exceptional specimen featuring Proustite crystals with Acanthite and Native Silver on Calcite!
This classic old museum piece dates back to the 1850's and is quite simply the finest specimen of German
Proustite crystals on matrix that I've seen or owned! The Proustite has been well protected and still has a
considerable amount of redness when exposed to direct light. The addition of Acanthite and Native Silver
wires makes the piece extraordinary. The matrix is covered by fine stacked crystals of white Calcite!

MIN#EXCEPTIONAL-29 NEW!

Tremendous plate featuring fine dendrites of Native Silver with Acanthite and Safflorite accenting!
This is a wonderful display piece from the classic Cobalt Mining District and is literally covered from one
end to the other with large dendritic structures of Native Silver. A peppering of grey Safflorite covers much of the
dendrites as does Acanthite drusy. This is incredible rich specimen and the display is beautifully presented atop white
Calcite covered surface. Much more impressive in person due to the difficulty of photographing sparkling surfaces.

A beautiful display piece with dozens of finely bladed crystalline balls of Azurite clustered together with
the occassional Azurite line seam between for contrast. This specimen dates back to the 1880s - 1890s and to
find a plate of this size and crystallization in such fine condition is very difficult. A great addition to any collection.

MIN#EXCEPTIONAL-32 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.

MIN#EXCEPTIONAL-34 NEW!

VERY RARE and quite impressive plate featuring Pyrargyrite and Acanthite with Heulandite on Calcite!
Without a doubt, this is the first Silver with Heulandite combination I've seen. The bottom close-up photo
displays the gemmy crystal blades of golden Heulandite sitting among the Acanthites. The Heulandite crystals
actually appear in several locations atop the white Calcite surface and I find this fascinating because this is not
a common mineral at the Samson Mine and there is only one photograph listed on mindat.org for the locality.
The magnified photo displays the incredible textbook form and luster of each Pyrargyrite crystal. They measure to
1 cm in size and are richly scattered atop the white Calcite crystal matrix. In excellent condition with few contacts.
This amazing cabinet plate is circa late 1800's. The Samson Mine was a famous Silver Mine that closed in 1910.
From the Samson Mine, St Andreasberg, St Andreasberg District, Harz, Lower Saxony, Germany.
Measures 14 cm by 17 cm by 5.3 cm in total size.
