2.7 x 1.5 x .5 CM (thumbnail)
A crystalized thumbnail of Cornish Torbernite with a bright apple-green color. Ex Dr T.B. Wilson collection, we do not have a mine attribution for this piece although it looks like a great match to Old Gunnislake Mine, but that is not documented. There are many Torbernite locales listed in Cornwall, most have crude plates or scattered crystals, relatively few have rosettes and dense clusters. A colorful English piece that is reasonable in cost yet choice.
Wheal Alfred, Phillack
7.3 x 6.5 x 3 CM (cabinet)
Cornish Pyromorphite from the prolific Wheal Alfred. Ex John Marshall and Douglas Creba with labels. Tiny grass green crystals on several sides of a blocky matrix. Wheal Alfred long ago produced a few very fine, world class Pyros which today are prized and very expensive when available. This is frankly not in that league but it is better than average, looks great magnified and a nice locality piece with good coverage.
Wheal Edward, Botallack, St. Just
6.8 x 4.1 x 1.3 CM (cabinet)
Rich, brilliant blue masses of Connellite richly covers a double sided matrix plate. Classic Cornish material, this rather rare Copper mineral is usually seen in specks and areas measured in millimeters, not dense multi centimeter masses. A lighter blue area of Langite is present also, but far more of this is Connellite. From the Ruth and Andy Palmer systematic collection, this are mostly massive, with colorful crusts but strong magnification shows very tiny crystals in a few area. Bright and impressive for this uncommon Copper specie.
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!
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.
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.

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. Ex Huber collection (Austria), in good condition there is some Quartz or Calcite overgrowths on some Chalcopyrites, and Pyrite is present in the matrix.
