Galena Pseudo after Pyromorphite -Classic locale
stock #0241-JM-331A
Wheal Hope, Perranzabuloe, St. Agnes District
Cornwall, England
2.8 x 2.3 x 1.5 CM (thumbnail)
price: $330
Worldwide mix summer

Classic Cornish thumbnail specimen of the very desirable Galena after Pyromorphite crystals from Wheal Hope. Small but distinct crystals of Pyromorphite have full changed to Galena but the form remains. Ex John Marshall collection, obtained by him before 1970. These Pseudomorphs are only known from a few spots in the world and all seem to have been found over a century ago. These are especially uncommon from Cornwall, and while to many people are just black and ugly, they are a prize to those who understand these things!
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.
Apatite- Ca rich Fluorapatite, classic casts after Anhydite
stock #15.1-339
Geevor Mine, Levant sect. Botallack-Pendeen Area
Cornwall, England
8.3 x 5.2 x 5.2 CM (cabinet)
price: $600
Spring update

A fine old Cornish classic, a cast composed entirely of Apatite crystals have formed casts after Anhydites. The specimen is crystallized on all sides with just a few spots of contact. Lustrous and sparkling and very three dimensional, the shapes of the Anhydrite crystals are sharply preserved. The Apatite crystals are very sharp, glassy, translucent brown color in hexagons with flat pinacoids. Choice, Ex KP hammond collection, these were at one time called Francolite which is now discredited but is a varietal name still in use.
Botallackite
stock #17.1-886
Cligga Mine, Cligga Head, Perranporth, Perranzabuloe, St. Agnes District
Cornwall, England
11.9 x 8.8 x 4.9 CM (cabinet)
price: $250
Pre Holiday 2017

A very large specimen of lustrous Botallackite from Cornwall. In several habits but mostly accicular free standing crystals in several vugs. This could be trimmed to make several specimens if desired, but is fine as is to my eye. A Cornish classic copper specie, a paramorph of Atacamite and Clinoatacamite, this specimen seems to have a druse of Langite (not x-rayed) as well. Botllackites is quite rare and when from other localities are not nearly as attractive as these.

A Cornish Chalcopyrite that is well crystallized and with good luster. Sharp trigons to 1.7 CM across are scattered on a thin plate with stained Quartz crystals between each.

Gem clear crystal in fine condition from this classic Cornish location. The crystal includes a crude but distinct internal "helix" pattern which adds considerable interest. A fine small specimen with delicate pale blue color and glassy luster.

stock #13.1-319
St. Austell District
Cornwall, England
5.6 x 3.6 x 1 CM (cabinet)
price: $280
Fall 2015

An old Cornish classic, this pseudomorph is a complete and sharp replacement of the original twinned Feldspar. No damage or missing areas, this is a perfect floater. Textbook form much like a crystal model. Sometimes called "pig's ears" these are not "beauty" type display minerals but they are distinctive and unique to these old finds. Not many turn up for sale, this one is the best and sharpest example we have seen available.

May 2015

A really good Cornish Olivenite with fine color and contrast to the matrix. There are several other Copper secondaries on the Quartz matrix that add nice color. The crystal druze is sizable and in excellent condition. Classic old material that displays well.
