CXC01J1 Dioptase
Ntola Mine, Mindouli, Pool Dept., Republic of Congo
8.4x 5.8x 3.8 cm
$130

A nice example of bright green dioptase in a vug, from recent finds at the Ntola Mine.  Quite good for the price, I think.  A price of $200+ would not be unreasonable. Sawn on the back. 







CXC01K1 Dioptase and Mimetite
Ntola Mine, Mindouli, Pool Dept., Republic of Congo
7.9x 4.3x 3.1 cm
$120

A nice example of bight green dioptase with nicely contrasting yellow mimetite, from recent finds at the Ntola Mine.  Quite good for the price, I think.







CXC01S Fluorite on Quartz
Xiayang Mine, Fujian Prov., China
5.0x 3.3x 3.2 cm
$48

A nice example of pale green fluorite from the recent finds in Fujian Prov.  The crystals are particularly clean of damage. 









CXC01T Cuproaustinite
Mina Ojuela, Mapimi, Durango, Mexico
7.0x 6.8x 5.6 cm
$78

A nice example of green cuproaustinite from recent finds at the Ojuela Mine.  This specimen has a fair amount of the mineral in a limonite vug. 







CXC01U Cerussite on Malachite
Mfouati Area, Bouenza Dept., Republic of Congo
5.2x 3.5x 2.3 cm
$46

A nice sample of cerussit eonmaalachite from recent finds in the Republic of Congo... this material is a little reminiscent of the older stuff from Rum Jungle, Australia. Saw marks on some edges. 







CXC01V Dioptase
Ntola Mine, Mindouli, Pool Dept., Republic of Congo
7.0x 5.0x 2.2 cm
$74

A nice sample of dioptase from Ntola, with a dusting of mottramite. Sawn back. 







CXC01W Dioptase
Ntola Mine, Mindouli, Pool Dept., Republic of Congo
5.8x 2.1x 2.6 cm
$58

A nice example of mimetite crystals on matrix, from recent finds at the Ntola Mine. Sawn back. 







CXC01X Plancheite and Quartz
Mindouli Area, Pool Dept., Republic of Congo
4.4x 2.1x 2.3 cm

A nice example of quartz over blue plancheite, from recent finds in the Republic of Congo. Saw marks on the back. 







CXC01Y Shattuckite with Quartz
Milpillas Mine, Cuitaca, Sonora, Mexico
8.6x 5.1x 4.5 cm
$66

A nice example of rather flat quartz crystals that have grown over shattuckite, from recent finds at the Milpillas Mine. 







CXC01Z Chrysocolla
Milpillas Mine, Cuitaca, Sonora, Mexico
5.8x 4.9x 4.9 cm
$38

A nice reference sample of bright chrysocolla from recent finds at the Milpillas Mine. 







CXC01R Plancheite and Quartz
Mindoui Area, Pool Dept., Republic of Congo
7.5x 4.4x 2.3 cm
$68

A nice example of quartz over plancheite, from recent finds in the Republic of Congo. 







CXC01Q Rhodizite-Londonite
Antsongombato, Betafo Region, Madagascar
3.6x 2.8x 2.0 cm
$40

A nice example of rhodizite-londonite on matrix, from Antsongambato. There is some liddicoatite frozen in the matrix, this is visible form the back. 







CXC01P Dioptase with Shattuckite
Mindoui Area, Pool Dept., Republic of Congo
6.4x 3.7x 4.2 cm
$145

A very beautiful example of dioptase with nicely contrasting blue plancheite. This piece hosts two very large compound crystals of dioptase, to 1.9 cm. The compound nature of the crystals and the sub-surface inclusions make it a bit difficult to photograph, but it is still a pretty good piece. Price at $275 in my show stock. 









CXC01N Dioptase on Quartz
Ntola Mine, Mindouli, Pool Dept., Republic of Congo
9.5x 6.5x 4.3 cm
$86

A very unusual example of dioptase directly on quartz.  There are only a few dioptase crystals here, some semi-embedded in the quartz, but it is rather unusual to see the two species associated like this. There are a couple crystals in the vug; the specimen has been sawn from behind to let more light through. It isn't perfect, but it is a very interesting and sparkly reference piece.  









CXC01M Dioptase, Plancheite, Malachite Calcite
Mindoui Area, Pool Dept., Republic of Congo
8.6x 6.0x 4.8 cm
$78

A very colorful example of dioptase (some complete, some not) with planchette, calcite, quartz, and possible chrysocolla, from recent finds in the Republic of Congo. 









CXC01K Dioptase
Ntola Mine, Mindouli, Pool Dept., Republic of Congo
8.5x 6.4x 6.3 cm

A cabinet sized specimen of dioptase form recent finds at the Ntola Mine. Sawn back.  I had a $160 price tag affixed to it in my show stock. 









CXC01J Dioptase
Ntola Mine, Mindouli, Pool Dept., Republic of Congo
6.5x 2.9x 4.9 cm

A very rich reference sample of dioptase on matrix from recent finds a the Ntola Mine. 







CXC01H Chalcedony var "Grape Agate"
Mamiju Area, Sulawesi Barat Prov., Sulawesi, Indonesia
6.4x 6.1x 2.1 cm
$62

A nice example of grape agate, with a somewhat lace-like appearance. 







CXC01G Barite on Fluorite
Guizhou Prov., China
4.5x 2.2x 1.9 cm
$42

A pretty miniature sized specimen, consisting of numerous white barite blades on a matrix coated with purple fluorite. This is displayable from the front and back.







CXC01F Chalcedony var
Mamiju Area, Sulawesi Barat Prov., Sulawesi, Indonesia
8.6x 5.1x 2.1 cm

A nice example of "grape agate" from finds made approximately 1 year ago in Indonesia. 







CXC01E Hemimorphite
Mfouati Area, Bouenza Dept., Republic of Congo
4.1x 3.4x 2.2 cm
$38

A nice reference sample of sparkly blue hemimorphite from recent finds int he Republic of Congo.  At first glance, it looks very similar to the material from Yunnan Prov., China.. This material has not been collected in any significant quantity since the 1960's, when French and Soviet enterprises were active in the area. Some scuffing present. 







CXC01C Gibbsite
Yunnan Prov., China
5.5x5.1x 4.1 cm
$58

A nice reference sample of blue gibbsite, from recent finds in southwestern China. 







CXC01D Fluorite on Quartz
Xiayang Mine, Fujian Prov., China
4.5x 2.2x 1.9 cm
$39

A well formed, but very dark blush-purple fluorite crystal from the Xiayang Mine, perched on a scrap of matrix.  With strong backlighting, you can see the color, but even without it, the form is rather nice. 







CXC01C Gibbsite
Yunnan Prov., China
5.5x5.1x 4.1 cm
$58

A nice reference sample of blue gibbsite, from recent finds in southwestern China. 







CXC01B Monazite
Ambatofotsikely pegmatite, Fidirana Commune, Betafo Dist., Vakinankaratra Region, Antananarivo Prov., Madagascar
3.2x 2.6x 1.3 cm
$42

A nice reference sample of monazite showing good crystal faces, from central Madagascar. 







CXC01A Dioptase
Mindoui Area, Pool Dept., Republic of Congo
8.7x 5.6x 2.1 cm

A nice cabinet sized example of dioptase crystals on a quartz-rich matrix, from recent finds in the Republic of Congo. 







CXC01A Dioptase
Ntola Mine, Mindouli, Pool Dept., Republic of Congo
1.8x 1.7x 0.85

A nice example of dioptase after something-- maybe placheite or shattuckite from recent finds int hr Republic of Congo. 







CXC02 Phosphophyllite
Huayllani, Canutillos subdistrict, Machacamarca Dist., Saavedra Prov., Potosi Dept., Bolivia
6.2x 5.1x 3.8
$175

An nice example of phosphophyllite from the "other" (more recent) Bolivian locality for the species.   The overall form and richness of this piece, comprised of hundreds of twinned phosphophyllite crystals, make for a particularly fine example-- this one is notable for the nicely isolated cluster pleasantly positioned on its matrix.

The most famous examples were discovered between 1950 and the late 1970's, at the Unificada Mine in the same department, but until this find, the extreme scarcity of those pieces made it nearly impossible for collectors to obtain specimens of this sought after species.  

These contemporary pieces obviously lack the depth of color present in the older ones, but are quite exceptional as examples of the species-- the richness and sheer amount of well crystalized phosphophyllite on these specimens is something not seen from any other locality.  

Phosphophyllite from Huayllani first appeared on the market around 2010, then somewhat disappeared.  These pieces come from a more recent discovery at the same location.  Initially, they were labeled "Colavi" or "Machacamarca," but we now have more precise information. 

This would be priced around $360 in the regular galleries. 







CXC03 Fluorite on Quartz
Huanggang Mine, Hexigten Banner (Keshiketeng Co.), Ulanhad League (Chifeng Prefecture), Inner Mongolia Autonomous Region, Chinan
7.5x 5.3x 3.1 cm

A very nice example of fluorite crystals perched on quartz, from recent finds at the Hunaggang Mine.  The fluorite crystals have a bit of edge wear, but they display an interesting phantom at approximately 45 degrees to the crystal's outer faces.  







CXC05 Ludlamite on Siderite
Huanuni Mine, Delance Prov., Oruro Dept., Bolivian
5.1x 4.1x 3.9 cm

A great example of ludlamite from Huanuni.  This comes from he same pocket as a group of specimens that are considered to be the best of species-- this is one of the humbler examples, but still a great example, especially for the price! Priced at $320 in my show stock. 







CXC06 Cerussite
Mfouati Area, Bouenza Dept., Republic of Congo
3.6x 2.6x 2.0 cm
$72

 A great example of reticulated smoky cerussite from recent finds in Mfouati. This is an excellent miniature specimen from the area, when you see the average quality of material that comes from here, you gain an appreciation for the complete ones-- especially in the case of a delicate mineral like cerussite. Most specimens that are extracted get completely butchered.   I would price this double in the normal galleries. 







CXC07 Creedite
Qinglong Mine, Dachang Sb ore field, Qinglong Co., Qianxi'nan Autonomous Prefecture, Guizhou Province, China
3.0x 2.4x 2.7 cm
$58

A beautiful ball shaped, "toenail" sized cluster of credit crystals from China.  Most Chinese creedites tend to be a bit flatter, usually plates of crystals, often radiating out from a central point but lying flat against their matrix.  For China, this is a particularly nice miniature. 







CXC08 Dioptase on Plancheite
MIndouli Area, Pool Dept., Republic of Congol
5.9x 4.3x 0.8 cm
$68

A beautiful example of green dioptase crystals scattered on beautifully contrasting blue plancheite, from recent finds in the Mindouli area. 







CXC09 Fluorite
Yindu Mine, Chifeng Pref., Inner Mongolia A.R., China
4.6x 3.7x 1.9 cm
$64

A very nice example of fluorite from find made last year at the Yindu Mine, showing the typical phantoming and blue/ purple zones.  I can't tell if the back is cleaved or etched, but the specimen is somewhat flat-- it actually has a nice effect of the appearance of the piece, int hat it allows more light to pass through and makes it possible to see all the subtile zoning and color concentrations within the piece.  It was photographed in a light box,  so you can see what I mean.  







CXC10 Cerussite on Malachite
Boko Songho-Mfouati Area, Bouenza Dept., Republic of Congo
3.4x 3.1x 1.3 cm

A very nice miniature specimen of cerussite on malachite, from recent finds in the Boko Songho area. While not entirely perfect, this one is unusually clean of damage-- it seems that the rather brutal extraction methods always leave either the cerussite shattered, or the malachite scuffed.  This one is really nice for the size....

The material from here reminds me a bit of the old material from Rum Jungle, Australia. 







CXC11 Axinite with Epidote
Canta Prov., Lima Dept., Peru
4.6x 3.x 4.2 cm
$72

A beautiful spray of axinite crystals, on matrix composed of tiny andradite garnets, with minor epidote.  There is some damage at the tips of the axinite crystals, but it remains a beautiful example nonetheless. 









CXC12 Hemimorphite
Mfouati Area, Bouenza Dept., Republic of Congo
4.8x 3.8x 2.6 cm
$48

Among the interesting new finds from Congo are several habits of hemimorphite.  Most come from various workings in the same general area, and the appearance varies from plates that are nearly identical to the botryoidal blue material from Wenshan, China, to clusters of white crystals that look similar to the Ojuela material, only more robust (like this one).







CXC13 Austinite
Mina Ojuela, Mapimi, Durango, Mexico
5.6x 3.0x 3.3 cm

A nice example of yellow austinite from Mina Ojuela.  You only ever see specimens of rather pale, small crystals from Utah, and then the occasional piece from Ojuela. This finds of the last year have produced a number of very good examples, and at least for now made decent pieces obtainable rather cheaply. 







CXC14 Shattuckite with Quartz
Milpillas Mine, Cuitaca, Sonora, Mexico
9.8x 3.3x 3.1 cm

A beautiful example of shattuckite overgrown in places with sparkly quartz. 







CXC16 Lollingite with Quartz, Fluorite and Manganocalcite
Huanggang Mine, Hexigten Banner (Keshiketeng Co.), Ulanhad League (Chifeng Prefecture), Inner Mongolia Autonomous Region, Chinan
5.6x 4.9x 3.9 cm

A nice example of sharp lollingite with quartz, colorless fluorite, and manganocalcite.  It can be displayed from a couple different angles 









CXC17 Plancheite and Quartz
Mindouli Area, Pool Dept., Republic of Congol
3.4x 3.2x 1.7 cm
$48

A nice example of plancheite and another green mineral overgrown by quartz, making for a colorful and rather sparkly specimen.







CXC18 Cuproaustinite with Cobaltoaustinite
Mina Ojuela, Mapimi, Durango, Mexico
6.4x 4.6x 5.2 cm
$48

A nice example of grayish cobaltoan austinite with spots of brighter green cuproaustinite from finds made last year at the Ojuela Mine. A nice reference sample. 







CXC19 Cerussite
Mfouati Area, Bouenza Dept., Republic of Congo
2.8x 2.6x 2.2 cm
$46

A nice example of a "toenail" sized (slightly roughly shaped) "sixling" from recent finds in Mfouati. It is a very good reference, when you see the average quality of material that comes from here, you gan an appreciation for the complete ones-- especially in the case of a delicate mineral like cerussite. 









CXC20 Quartz var. Amethyst
Madhya Pradesh, India
7.0x 5.5x 3.8 cm
$85

A nice example of amethyst from a find made approximately 2 years ago. I particularly like the appearance of the small, purple amethysts on a contrasting black basalt matrix. Priced at cost. 









CXC21 Dioptase on Plancheite
Mindouli Area, Pool Dept., Republic of Congol
4.8x 3.5x 3.1 cm
$76

A nice example of green dioptase crystals on nicely contrasting plancheite from recent finds near Mindouli. 







CXC22 Axinite
Canta Prov., Lima Dept., Peru
5.7x 2.7x 2.4 cm
$66

A nice example of blade-like axinite crystals, form finds made approximately 3-4 years ago. 









CXC23 Quartz
East Coleman Mine, Jessieville, Garland Co., Arkansas, United States
6.2x 1.5x 1.0 cm
$23

A very. very clear quartz crystal. It's just unusual to see such sharp, clear pieces.... In Madagascar I can search through burlap sack after burlap sack full of quartz crystals, and not find a single piece as clear or sharp as these Arkansas examples.


I honestly don't understand the pricing of these things... sometimes you'll see one the same size for $100, sometimes it's cheaper.... sometimes it's some exorbitant amount and they are priced by the gram.... whatever the case, I like my price.










CXC25 Hubnerite with Quartz
Mundo Nuevo District, Santiago de Chuco Prov., La Libertad Dept., Peru
5.6x 5.4x 4.8 cm

A nice reference sample of hubnerite, with a spray of (lightly reddish) black crystals on quartz.  Not perfect,  but a nice example for the price.  These were found around 6-7 years ago. 









CXC26 Dioptase on Plancheite
Mindouli Area, Pool Dept., Republic of Congo
7.5x 3.0x 1.0 cm

A beautiful example of green dioptase, on a plate of nicely contrasting blue plancheite, from recent finds in the Republic of Congo.  







CXC27 Hutchinsonite with Orpiment
Quiruvilca Dist., Santiago de Chuco Prov., La Libertad Dept., Peruu
5.5x 4.0x 2.3 cm
$44

A nice sample of the very rare thallium-bearing mineral hutchinsonite, from finds made a couple years back at Quiruvilca.  These were first found in the 80's and all but disappeared into collections.  Over the last 3-4 years, a few small new finds of the material have been made. This one has a number of bright crystals on a dark matrix. 







CXC28 Parisite Pseudomorph
Mt. Malosa, Zomba, Chilwe Alkaline Area, Malawi
5.4x 1.7x 1.6 cm
$62

A decently sized example of a parasite pseudomorph from Mt. Malosa.  These are a mixture of goethite, quartz, bastnaesite, and a number of other rare earth minerals.







CXC29 Malachite
Boko Songho-Mfouati Area, Bouenza Dept., Republic of Congo
9.8x 7.0x 5.6 cm

A nice example of malachite from the Republic of Congo--- NOT the Democratic Republic of Congo, where 98% of the malachite on the market comes from.  Most of the malachite from the Republic of Congo is excavated by Chinese or Lebanese firms, then sent to China to be processed into finished goods. Specimens are not common!







CXC30 Scorodite
Mina Ojuela, Mapimi, Durango, Mexico
7.5x 2.5x 4.0 cm
$54

A decent reference example of scorodite crystals from Mina Ojuela. This material is incredibly rare, but last year there were a few finds of this material. This one displays weak color change, and has a group of crystals concentrated in a vug. 







CXC31 Cerussite on Malachite
Mfouati Area, Bouenza Dept., Republic of Congo
4.3x 3.2x 1.1 cm
$64

An unusual example of reticulated cerussite, from an unusual locality.  The cluster is obviously reticulated, but is oddly rounded.  And the locality is also notable-- you don't really see many example from here, except (recently) for the darker smoky crystals. 







CXC32 Cuproaustinite
Mina Ojuela, Mapimi, Durango, Mexico
2.6x 2.2x 1.4 cm

A very nice thumbnail sized example of cuproaustinite from recent finds at Ojuela; this one has particularly good color. 









CXC33 Parisite Pseudomorph
Mt. Malosa, Zomba, Chilwe Alkaline Area, Malawi
3.2x 2.4x 2.4 cm
$48

A rather sharp example of this material from Mt. Malosa.  They are a mixture of goethite, quartz, bastnaesite, and a variety of rare earth minerals-- the exact composition of each one is a little different.







CXC34 Barite
Sounion Mines, Lavrion, Attica, Greece
7.4x 4.8x 2.6 cm
$39

A nice example of blady barite from one of the oldest mining localities on the planet.







CXC35 Pyromorphite with Malachite
Mfouati Area, Bouenza Dept., Republic of Congo
11.9x 11.2x 3.0 cm
$66

A reference sample of pyromorphite with malachite, from recent finds around Mfouati.  







CXC36 Orpiment
Quiruvilca Dist., Santiago de Chuco Prov., La Libertad Dept., Peruu
7.4x 6.2x 3.5 cm
$76

A nice example of lustrous and rather glassy orpiment crystals, from finds made several years ago at the Quiruvilca Mine.  This mine produced a lot of material in the 70's and 80's, and again for a brief period in the early 2010's, but the introduction of more advanced mining methods means that little to nothing has emerged int he last few years. 







CXC37 Quartz (Japan Law Twin)
Mundo Nuevo District, Santiago de Chuco Prov., La Libertad Dept., Peru
5.0x2.8x 2.4 cm

A reference example of quartz from the Mundo Nevo workings.  I can't tell if one side of the twin is etched or broken.  Either way, a decent reference for the price.
