MIN#Denver2015-101 NEW!

Graceful and artistic display of Native Wire Silver rising up from a Calcite and Acanthite matrix!
This is one of the prettiest wire Silvers I've seen in a long time from Guanajuato. The largest curling
wire rises 4 cm above the matrix before looping around at the top. Smaller curling wires can be seen
around the periphery and all are bright and lustrous. A very impressive wire Silver miniature for sure.
From Guanajuato, Mun. de Guanajuato, Guanajuato, Mexico.

MIN#Denver2015-103 NEW!

Excellent combination specimen featuring large tabular crystals of Golden Barite with Stibnite sprays!
This is the first of these that I've seen in years and the Barite crystals are the largest I've ever seen
from this locality. They glow a deep golden coloration and are gemmy to translucent (more gemmy at
or near the edges and tips), with a strong surface glassy luster. The Stibnite sprays jut outwards near
the lower right and are complete and undamaged. A very attractive combo that is almost impossible to
find at the shows these days. This specimen came from an older collection and is in excellent condition.
From the Cavnic Mine, Cavnic, Maramures County, Romania.
Measures 6.5 cm by 5.4 cm by 4.2 cm in total size.

MIN#Denver2015-104 NEW!

Aesthetic specimen featuring blue Azurite crystal blades with chatoyant Malachite!
This is one of the better Bisbee Azurite with Malachite specimens of this size range that I've seen in
a number of years. The blades are sharp and very lustrous, standing upright atop the gossan matrix
with minimal contacting. They are accented by Malachite, including the two wonderful radial sprays
of chatoyant green near the lower edge. The eye appeal of this 125 year old specimen is excellent!

MIN#Denver2015-105 NEW!

Fine crystals of Beryl var. Goshenite nestled atop Schorl Tourmaline!
This is a really cute specimen. A group of these fine Goshenite on Schorls recently came to market
and I cherry picked some of the best specimens from those available. The Goshenites are mostly
doubly terminated and gemmy to translucent with glassy crystal faces. They contrast very well
with the shiny black surfaces of the Schorl Tourmaline crystals they sit atop. In excellent condition.

A seldom seem locality combination from the Pallaflat Mine which has been worked since the
1880's. The Calcites are centered perfectly and exhibit reddish-brown tips due to a slight inclusion

Denver2015-202EpidoteQuartzPrinceofWalesIslandAlaska13cm.jpg (377500 bytes)

MIN#Denver2015-108 NEW!

Exceptional combination specimen featuring dark green Epidote crystals with Quartz on matrix!
This is one of the finest plates of Epidote from the Green Monster that I've seen in years. It's also unusual because it
displays large, terminated Epidote crystals standing upright in isolation among the crystal-clear Quartz points. Usually
these specimens appear as clusters of criss-crossing Epidote crystals so this specimen really stands out. I prefer the
isolated look over the clusters and this specimen is certain to please with it's glassy-lustrous crystals and lack of contacts.
From Green Monster Mountain, Prince of Wales Island, Ketchikan Dist., Prince of Wales-Outer Ketchikan Borough, Alaska.

A rich scattering of fine Gold crystals is spread across the surface of this grainy Quartz matrix.
I don't have an exact date for this specimen but I would estimate it dates back to the mid to late
1800's. This would make a great addition to a type Gold or North Carolina mineral collection.

Denver2015-192DatoliteBetaQuartzDalnegorskRussia180mm.jpg (369068 bytes)

MIN#Denver2015-113 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.
From the Bor Pit, Dal'negorsk, Kavalerovo Mining District, Primorskiy Kray, Far-Eastern Region, Russia.
Measures 18.3 cm by 14 cm by 7.4 cm in total size.

Denver2015-4CopperJeromeArizona7cm.jpg (418824 bytes)

MIN#Denver2015-115 NEW!

Very rare specimen featuring dendritic Native Copper crystals branching outwards atop matrix!
This is a Jerome, Arizona Copper specimen and this has to be one of the most difficult localities to find
anywhere. I've only seen two or possibly three specimens of Native Copper from Jerome in all my years
of searching and this is by far the finest of those. The crystalline structure of the specimen is very distinct
and dendritic and it's apparent the crystals formed inside a very narrow pocket inside matrix, hence there
somewhat flattened appearance. The crystals are lustrous beneath an antique patina which is original.
From the Jerome, Verde District, Black Hills, Yavapai County, Arizona.

surface that really sets off some serious flash under any type of lighting. One of the first I've seen.

MIN#Denver2015-117 NEW!

Extremely rare specimen of Native Silver wires with Galena on layered matrix!
There are numerous patches of Native Silver wires atop and between the layered matrix and some
display wires of good thickness like the wires near the bottom. This is a very rich specimen and one
of the finest examples I've encountered from the Broken Hill locality. They are so rare that I only
come across one every few years or so and this is by far the largest plate (cabinet sized) I've seen.
From Browne's Shaft, Junction Mine, Broken Hill, Yancowinna Co., New South Wales, Australia.

Denver2015-169FluoriteArbouetSussauteFrance10cm.jpg (343736 bytes)

MIN#Denver2015-118 NEW!

Lovely specimen featuring a cluster of gemmy-clear golden-yellow Fluorite cubes from France!
This is a beautiful specimen but it's also pretty neat because the bottom side is a geode-like recess,
indicating that the cluster formed atop a cast matrix. The Fluorites are uniform in size and average
around 1.8 cm. They are very transparent and glow with a brilliant color through highly lustrous,
glassy surfaces. In excellent condition and very well trimmed. The specimen sits like a golden hill
and most Fluorites I've seen from this locality are opaque to translucent, not gemmy like this one.
From the Birrity Quarry, Arbouet-Sussaute, Pyrénées-Atlantiques, Aquitaine, France.
Measures 5.5 cm by 10 cm by 6.2 cm in total size.

Denver2015-201CalcitePughQuarryOhio15cm.jpg (307897 bytes)

MIN#Denver2015-119 NEW!

Impressive plate of brown phantomed Calcite crystals atop dark brown Fluorite!
This is one of the larger Pugh Quarry Calcites I've seen in recent years. It resembles a mountain
with its peaks and valleys and translucent white tips. Most of the Calcite crystals display a brown
center which may be indicative of the brown Fluorite matrix beneath or simply a brown Calcite
phantom. This specimen displays very well with flashy surfaces and is in excellent condition.
From the Pugh Quarry (France Stone Co. Custar Quarry), Weston, Wood County, Ohio.
Measures 15.5 cm by 11 cm by 7.2 cm in total size.

since most specimens have now disappeared into private collections and no new discoveries

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.
