Phosphophyllite - crystals in fossil clamshell cast.
stock #21.1-138
Huaylliani Phosphphyllite Diggings, Huayllani, Canutillas. Machacamarca,
Potosi, Bolivia
7.2 x 4.9 x 2.8 CM (cabinet)
price: $3800
Early summer 2021

Fine Phosphophyllite crystals nearly fill the void of a fossil clam shell with the center area still open. The center void has dozens of sharp terminations surrounding the middle. Some crystals show the classic "swallowtail" twinning habit and all are a translucent apple green. This is one of the very best specimens I have seen from a small find made in 2009-2010. Phosphophyllite in sizable crystals is rare and one of the "holy grail" species. Outside of Bolivia nearly all other specimens are quite small, measured in millimeters, and most are micros. This locality is about 45 KM from the more famous mines at Cerro Rico which is also in Potosi, Bolivia. The best specimens from Cerro Rico are highly prized, being both rare and some the most expensive mineral specimens in the world. This smaller find at Huaylliani more than a decade ago was huge news in the mineral world back then. While the crystals from here are not as gemmy and clear as the best from Potosi, they are still very fine and would rank as the second best in the world. The find is long ago finished and these are now quite prized as well. The largest crystals on this piece are over 2 CM but most are smaller. An unusual piece, very large for the area, this has both lustrous areas and some lightly frosted crystal faces. Minimal matrix, this is over 78 grams of nearly pure Phsopophyllite. The shape of the clam shell is still somewhat visible on the backside but the open vug of the green Phosphophyllite crystals is the real star here. In excellent condition overall, a few small Iron stains are present on some edges though the crystals are very clean. An outstanding piece from this important find.

Barite on Rhodochrosite
stock #8.AE-814
Cerro Warihuyn - Miraflores, Huamalies Prov.
Huanuco Department, Peru
4.3 x 4.1 2.7 CM (miniature)
price: $120
Early summer 2021

A gem clear rosette of undamaged Barite crystals on Rhodochrosite from Huanuco, Peru. This Barite find has produced many fine pieces over the past few years and is now well established as a modern classic locale. The blades of this Barite are perfectly clear, lustrous and are attached only by a small point on the crystalline Rhodochrosite matrix. Selected carefully from many pieces this one has superior form and condition.

Chrysoberyl var Alexandrite- type locality
stock #16.1-394-(CN1031)
Izumrudnye Kopi, Malysheva, Ekaterinburg, Swerlovskaya Oblast, Mid Urals
Urals Region, Russia
3.1 x 2.6 x 1.9 CM (thumbnail)
price: $750
Early summer 2021

From the classic, type locality this is a cluster of Alexandrite crystals with excellent color change from green to red. This is nearly all Chrysoberyl with just a minor Mica and Quartz matrix. The crystals all show twinning and the largest is a sixling twin. From the collection of Charles M Noll, the edges of all crystals are translucent and in person the color is quite vibrant. It is quite hard to find any Alexandrite from the Urals and especially from the type locality. This is certainly a fine example.

Descloizite
stock #AX-9-042
Berg Aukus, Grootfontein District
Otjozondjupa Region, Namibia
5.8 x 5.1 x 3.3 CM (cabinet)
price: $140
Early summer 2021

Bladed leafy habit Descloizite crystals are clustered in bunches on smaller Descloizites. The Descloizites are mostly a dark brown color but have zones of orange to reddish as well. Fairly lustrous and mostly in good condition, there are a few broken blades that can be seen at some angles which is typical. The price reflects the imperfections but in person the damage is not really distracting. A good value for a well formed group of Descloizite crystals. The famed Berg Aukus Mine was the world's greatest source of this specie.

Wulfenite with Mimetite on Quartz
stock #15.1-580
San Francisco Mine, Cucurpe
Sonora, Mexico
7.8 x 3.4 x 3 CM (cabinet)
price: $120
Early summer 2021

An unusual matrix for this Wulfenite from the famed San Francisco Mine, this is a cluster of Quartz crystals holding many small widow-pane clear Wulfenites and scattered Mimetites. The Mimetites are in both the typical orange balls and in sharp needle crystals. Under magnification the associations are amazing. Most San Fransisco Wulfenite is incredibly fragile and when on the gossan matrix they also tend to crumble. With the Quartz matrix is quite stable and strong. The overall condition for this is excellent too.

Cuprite on Chrysocolla
stock #AX-19-263
Mashaba West Mine, Kolwezi Mining District
Lualaba Province, Democratic Republic of Congo (Zaire)
5.1 x 4.1 x 3.8 CM (small cabinet/large miniature)
price: $580
Early summer 2021

Perfect and with fine form, dark red Cuprite crystals are perched on contrasting blue-green Chryosocolla. Modern classics, good Cuprites from this region are highly regarded. These crystals, besides being damage-free, are also gemmy, with any backlight they glow a ruby red color. The photos here are made with normal lighting to give a fair idea of the specimen without extra enhancing illumination. We have seen many specimens from this locality but very few are so perfect. The octahedral crystals here show both twinning and some elongation. An older piece, (we believe from the 1970-80 era), with several earlier labels from previous collections, including Paul Jung, James Lewis, Greg Kirby. This is certainly a choice specimen far beyond average quality.

Fluorite on Barite
stock #AX-19-242
Berbes, Ribadesella
Asturias, Spain
4.8 x 2.8 x 2.2 CM (miniature)
price: $290
Early summer 2021

A cute miniature with very esthetic form. Sharp, gem clear Fluorites with a slight violet hue are nicely perched on cream white Barite blades. In excellent condition as seen, it is not easy to find both the delicate Barite blades and the Fluorites in pristine condition. The Fluorites have very tiny edge modifications as is the desirable form from this region. Classic form and from a classic locality, the cubes are up to 1.3 CM diagonal.

Semseyite, Siderite (Spharosiderite) and Quartz etc.
stock #9.1-021
Baia Sprie
Maramures, Romania
6.9 x 6.7 x 4.3 CM (cabinet)
price: $180
Early summer 2021

Multi-specie specimen with at least 8 minerals present, the most significant being a cluster of Semseyite from this type locality. This is a complex matrix holding milky Quartz crystals that are surrounded by Siderite and Pyrite. Semseyite in radial form sits on one edge and Galena, Sphalerite, Chalcopyrite and Dolomite are evident too. Baia Sprie is the type locality for Semseyite, but it was more more commonly found at Baia Mare. Semseyite is fairly rare at Baia Sprie. Long known as Felsobanya, this locale had been mined since the 14th century, so by any definition the locality and this specimen are classics. The mines have all been closed since 2006. Ex Ernie Schlichter, this is a good example and especially interesting with magnification.
