Vivianite with Muscovite - Rare locale
stock #18.1-AX-12-340
Cigana Mine, Conelheiro Pena, Doce Valley
Minas Gerais, Brazil
5.4 x 3.7 x 2.6 CM (small cabinet/ large miniature)
price: $380
Spring update

A choice and rare Brazillian Vivianite from a pegmatite famed for interesting and rare Phosphates. In excellent condition, sizable for the locale and translucent to transparent with a blue green color. The main rosette cluster is over 5 CM tall and the associated Muscovite is significant, this was notable for this one time find in 2007. Pegmatite Vivianites are almost never this large or good since most Vivs are found in Sulfide mines. This discovery was significantly different.
Emerald with Quartz crystals
stock #18.1-205
Mina Amarillial, Cosquez, Municipio de Muzo
Boyaca, Colombia
4.2 x 2.2 x 1.9 CM (miniature)
price: $480
Spring update

Light to mint green Beryl (Emerald) crystals make up most of this specimen with only a thin shard of matrix showing on one edge. Crystallized Beryla are on all sides, almost a floater. The Quartz prisms are sharp and clear contrasting with the Beryl. Crystallized quartz is rare in Colombian Emerald specimens, much more typical is Calcite or Dolomite. This is from a little known spot in the famed Boyaca region. In Colombia only 2 or 3 mines have ever produced Quartz crystals intergrown with Emerald. There are some chipped or contacted crystals but also many perfect, sharp Hexagons with good transparency and luster.
Volborthite - Vintage, classic
stock #18.1-202
Syssersk, Middle Urals, Permskyaya Oblast
Urals Region, Russia
5.8 x 4.9 x 2.3 CM (cabinet)
price: $125
Spring update

A very old specimen ex Wards with notes in the hand of George English on label, vintage about 1913-24 from label design. Typical platy crystals and masses on matrix Emerald green to yellow colors. A second old label enclosed is from J. Bohm in Vienna, which contradicts the Wards label locale as being Wreskresenskysch. Based on Mindat details it is possible to be from Sofronovskii the type locality which is in that area. While not a stunning display piece the color and form are good. An old price tag of 3.00 on the piece, a fortune at that time for this was then a very rare specie.
Pharmacosiderite- very old classic
stock #18.1-201
St Day United Mines, St Day, Gwennap CP
Cornwall, England
4.5 x 3.2 x 2.7 CM (miniature)
price: $350
Spring update

A fine vintage specimen of crystallized Pharmacosiderite, a rather rare specie and a Cornish classic. The label on this specimen dates to pre 1870 when the Mines were absorbed and names changed. The crystals are as always best seen with magnification (or great eyesight!) they are very sharp and distinct, rich green, lustrous, glassy cubic and transparent to translucent. A very elegant small piece with a Frieburg collection label that adds a nice provenance.
Melanochalcite/ Tenorite with Cuprite Chrysocolla etc
stock #18.1-203
Bisbee, Warren District, Mule Mts., Cochise Co.
Arizona, United States
4.4 x 3.2 x 4 CM (miniature)
price: $90
Spring update

A classic old Copper secondaries specimen with several old labels including a Wards label from 1913-22 vintage. Melanochalcite forms a thin zone around Cuprite in Nodules like this near Bisbee. This is an old varietal name for Tenorite which was first described in 1902. Other Copper secondaries are present as are several old handwritten labels in Italian. A colorful antique specimen.
Talc- Ps after Enstatite crystal- excellent classic
stock #18.1-199
Bamble (Bamle)
Telemark, Norway
3.9 x 2.6 x 1.3 CM (miniature)
price: $360
Spring update

Superb pseudomorph in a complete crystal, double terminated and far sharper than any other I have seen. Classic specimen with a Wards label dating this to over 100 years ago, (after 1913 shortly after George English began to work there). The label bears his handwriting. The Talc is the Steatite variety and more hard than other Talc so the condition of the replacement is nearly perfect. A fine piece for a Pseudomorph suite, and a great old classic on its own.
Elbaite - curved, rehealed crystal
stock #18.1-197
Barra de Salinas Mining District, Coronel Murta
Minas Gerais, Brazil
3.8 x 3. 2.8 CM (miniature)
price: $390
Spring update

An older, fat and substantial Elbaite crystal with a slight curve where it has rehealed. Multi color, 48 grams and with a white fibrous zone at the bend point. There is scattered bits of Clevelandite on a few faces. Good luster and quite sharp complex termination. Better in person too.
Fluorite with Carthage Corner habit
stock #16.1-574
Elmwood Mine, Carthage
Tennessee, United States
10.3 x 6.2 x 5.6 CM (cabinet)
price: $425
Spring update

A clean textbook quality example of a gemmy Carthage corner Fluorite. The larger cube has typical frosted, stepped faces and translucent purple surfaces but the corner is glass smooth, perfectly colorless and gem clear, a window into the interior of the crystal. A modern classic habit from the Elmwood mine, this is much more impressive in person and an esthetic mineralogical curiosity.
