Sierra Rica, Municipio de Manuel Benavides, Chihuahua, Mexico

7.5 X 7.2 X 3.3cm

Rosette-like modified crystals of  deep blue Azurite to 1.2 cm with good-as-it-gets luster are scattered and clustered across a matrix of bluish white clay/chrysocolla/other on a base of small "cockscomb" quartz crystals. It is contacted on the lower edge and lower-right region (visible as medium blue areas in the photo on the left), but still the best I've seen of these, and could be trimmed to a pristine miniature- to small cabinet-sized piece. Note: this is one of two parallel series of small prospects, occurring on either side of the same canyon and visible from aerial photographs and common mapping applications. The other is called San Carlos, and is noted for its Vanadinite +/- Calcite specimens.  Despite their occurrences merely a few hundred meters south of the US-Mexico border, a view from above clarifies myriad reasons no one should ever go there without official permission and support.

San Pedro Mine, San Pedro Corralitos, Municipio de Casas Grandes, Chihuahua, Mexico

3.2 X 2.2 X 2.2cm

Competition-level thumbnail from this famous locality featuring a 2.0cm-wide ball of Mimetite laying on a matrix of the same. The color and luster are tops for the locality, with golden to slightly orangish yellow botryoidal crystals whose multiple minute terminations provide for a rolling satiny luster and lively appearance. No damage; this would be a complete floater save for one small point of attachment on the back, visible on the left side of the specimen in the photo on the left.

Pyromorphite on Malachite

Pizza Pocket, Brown’s Prospect, Rum Jungle, Batchelor, Coomalie Shire, Northern Territory, Australia

5.3 X 4.7 X 2.5cm

Lustrous olive-green Pyromorphite crystals, both isolated and in clusters, on moderately lustrous, deep forest-green balls of Malachite. This color combination is characteristic of this one-time find and stands out from any other pyromorphite locality. There is a small area of bruising visible on the lower-right "ball" in the photo on the left, and at least two very small crystals are broken. I could easily trim this out, but personally prefer this sculptural piece as it is.

Cuprite on Copper

Rubtsovskoe Cu-Zn-Pb Deposit, Rudnyi Altai, Altaiskii Krai, Western-Siberian Region, Russia

9.7 X 6.6 X 6.0cm

Stout specimen of lustrous Cuprite crystals on a matrix of native Copper that has the patina of an old US penny. The apex Cuprite measures 3.2 X 2.7 X 2.6cm, and caps a series of other bright  Cuprites on the Copper base. There is no notable damage anywhere! Even the one small, slightly irregular face, visible just to the right of the frontal termination of the apex Cuprite in the photograph on the right, appears to be the nearly successful attempt to form an additional face similar to the ones clearly visible in the photos to the right! As quickly as they emerged a few years ago, specimens from here have already been entirely absorbed by the market!

Tsumeb Mine, Tsumeb, Otjikoto Region, Namibia

7.2 X 6.5 X 4.7cm

Richly covered specimen from a classic locality comprising intergrown Dioptase crystals to 1.5cm in length, commonly doubly terminated,  with only minor contacting restricted to the trim-edges of the piece (shown as lighter areas in the photograph to the left). The luster is glassy, and the crystals are translucent with numerous gemmy terminations. The color is most like the center photo to the right, which also shows small Calcite crystals with pistachio green Duftite/other. A latest generation of small, gemmy, emerald green Dioptase crystals provide sparkling accent to a few of the earlier, more deeply colored Dioptases.

Morenci Mine, Morenci, Copper Mountain District, Shannon Mountains, Greenlee County, Arizona, USA

6.8 X 5.5 X 4.2cm

Add this piece to any list of the most unique Morenci specimens either you or I have seen, consisting of a knob of white and tan matrix completely covered by three distinct zones of Azurite: 1) a moderately lustrous, true-blue zone of small intergrown blades (the lower 70% of the specimen in the photo on the right), 2) a thin band of navy blue that transitions into 3) clusters of azurite "balls" that are lighter in color with satiny luster at the top of the piece. No damage to speak of. Ex. Mark and Nikola Pecha Collection.

Pingtouling Mine, Liannan County, Qingyuan Prefecture, Guangdong Province, China

3.8 X 3.2 X 2.1cm

Aesthetic arrangement of lustrous, yellow-orange Mimetite crystals to 4mm. The wreath-like concentration of the crystals adds a nice touch as the largest occur mostly on the outer edges, providing a slight radiating effect. There is one small area of contacting that is barely noticeable, and one other crystal has a small chip, but these are lost in the saturation of strongly colored, locally gemmy crystals of Mimetite! Regardless, any possible distractions could be professionally removed and have been factored into the pricing.

San Andrés Mine, Espiel, Córdoba, Andalusia, Spain

5.5 X 5.0 X 4.0cm

Some argue that the color and luster of more recent specimens from here are "better," but I find them to be nearly indistinguishable from many of the Daoping pyromorphites, except the Chinese pieces are generally more aesthetic. The color on these earlier pieces, on the yellow side of greenish-yellow, is more distinctive. This one also has good luster, and the coverage extends to the back where the crystals have top luster. Including the crystals on the back, there may be around half-a-dozen mall broken crystals, but none that I find remotely distracting from the overall display quality. Note: the colors in the photos are accurate for my displays, even at the major shows, but this appears a bit more yellow in sunlight.

Tsumeb Mine, Tsumeb, Otjikoto Region, Namibia

6.6 X 3.8 X 2.5cm

A cluster of glassy, translucent to gemmy, mostly terminated Mimetite crytals. The color ranges from soft orangish yellow in the wider-diameter crystals to golden yellow in the later smaller ones. The larger crystals are nearly all contacted, but I believe they "bridged" the pocket and have separated from the opposite wall. Conversely, the late gemmy crystals almost all show sharply tapered complete terminations, suggesting they grew protected by the framework of earlier crystals.

9 Level, Jersey Vein, Bunker Hill Mine, Kellogg, Coeur d’Alene District, Shoshone County, Idaho, USA

2.8 X 2.5 X 1.4cm

I acquired this thumbnail from my late friend and well-known mineral dealer Harvey Gordon when I was given first option on his personal collection after he passed. Pyromorphite is my favorite mineral, and Bunker Hill is my favorite locality for the species. This piece features a classic arrangement of "wet-looking" hoppered crystals beginning with a soft tannish orange at the base, through yellowish orange then orangish yellow through the middle, with bright greenish yellow tips, and is missing only one small crystal on the back. An unusual feature is the occurrence of small needles of brown Pyromorphite ("Endlichite?") on preferred faces of around 40% of the earlier colorful crystals. Note: Harvey was the first mineral dealer to bring these to market in the early 1980s, and this offering is widely credited with elevating aesthetic mineral specimens into collectable works of art with investment potential, especially for Americans.  But, I won't argue with any other dealers who want to take credit for this distinction!

Daoping Mine, Gongcheng County, Guilin Prefecture, Guangxi Zhuang Autonomous Region, China

7.8 X 5.4 X 3.0cm

Classic Daoping! Lustrous crystals of Pyromorphite spread across the ridges and valleys of an ivory white matrix (quartz/other?). The color range of the best pieces from here, in my opinion, encompass the same range as a vibrantly fresh lime or kiwi cut through the middle; with deeper tones matching the deeper forest green coloration at or near the skins of the fruit, and the latest, commonly gemmy tips matching the light yellowish green of the fruits' internal glow.  No damage save a few scattered small crystals, which are barely visible and essentially impossible to point out even in the photo on the left!

Azurite with Malachite

Bisbee, Warren District, Mule Mountains, Cochise County, Arizona, USA

2.6 X 2.5 X 2.1cm

Large and lustrous Azurite partially altered to chatoyant green Malachite personally collected by the famous Dick Graham and passed on to Mike Baumann circa 1972. I purchased Mr. Baumann's collection in the early 2000s (more on this soon) and will begin to trickle specimens out with this offering. The main Azurite on the top is 2.6cm long and doubly terminated! The color is a bit more blue than the photos show, but still the blackish blue that is common for Bisbee. Overall, the quality is similar to the best from the recent finds at Milpillas, Mexico, but the dark matrix is absolutely Bisbee. No damage except on the bottom  and part of one side where it separated from the pocket.  A classic with strong provenance!

#PC-009          $325


Red Cloud Mine, Silver District, Trigo Mountains, La Paz County, Arizona, USA

3.7 X 3.0 X 1.9cm

Classic presentation of reddish orange, glassy, translucent to transparent crystals of Wulfenite to 0.8 cm on a matrix of brown to creamy white Calcite/Siderite. Based on its preparation, this is certainly from the Collector's Edge mining efforts of the early 2000s. In great condition, the only "damage" is minor separation of crystals along the trim edge. All of the major crystals are perfect.

Pb and Cu Secondaries I

Cuprite on Copper Psuedomorphs after Cuprite

Rubtsovskoe Cu-Zn-Pb Deposit, Rudnyi Altai, Altaiskii Krai, Western-Siberian Region, Russia

4.0 3.7 3.2cm 2.6cmxtal

One of the top 1% from this recent and unique find from Russia, where complex primary mineralogy and a fluctuating water table created several overlapping zones of "secondary" oxidation/reduction. This miniature captures part of this paragenesis in exacting detail, with a prominent, 2.6cm-wide, composite crystal showing an octahedral grouping of stout Copper crystals psuedomorphing an earlier Cuprite, with a partial epimorph of lustrous, dark reddish purple Cuprite. This  perches on a matrix of smaller Copper after Cuprites and lesser Cuprite with non-oriented copper crystals.  Under a loupe, there is a 3-4mm "rough"edge on the very base of the main Cuprite crystal. I'm not certain if it is a contact, but is too small to be obvious for even a seasoned collector, and is considered in the price.

Pure Potential Mine (North Geronimo Mine), Silver District, Trigo Mountains, La Paz County, Arizona, USA

5.3 X 3.8 X 2.2cm

Lustrous fire-engine red vanadinite from Arizona, with a custom lucite base! The crystals are up to 6mm long, and many are hoppered. There is a single crystal missing near the center of the specimen, but it is difficult to see even in person; regardless of the fact that it needs to be pointed out to be noticed, once I found this tiny blemish, I reduced the original price by more than 50%. Great visual impact and presentation!
