Balydonite -classic locale
Penberthy Croft Mine, St. Hillary
8 x 6.7 x 4.7 CM (cabinet)
A colorful and attractive very old Balydonite specimen from Cornwall with rich density. Ex Lechner collection (Austria) a mid to late 19th century collection that had also absorbed several earlier collections. The collection was dispursed in 1940-50 era. In 1969 sold to John Marshall via Schortmanns. This specimen is well over 100 years old, perhaps much older. The original label does not specify the mine but with the Lechner collection number (7132-13-23) it can be confirmed that this is in a sequence from the famed Penberthy Croft, and the habit etc is a perfect match for this location, which is also the type locality. The mine closed in 1840. There are several other species present that are not identified but what appears to be an area of Cornubite is noted as is some areas where the Balydonite has partly covered by a bluish-white mineral. Overall a choice classic example that has several possible display angles. Labels from Schortmann and Marshall are included.
A fine old Cornish specimen with a large spray of Torbernite (4 CM across) nicely perched on matrix. Great history with previous owners Hugh Ford, J. Cilen, Larry Conklin and John H. Marshall collections. This was advertised for sale by Larry Conklin for 250.00 fourty years ago. The specimen is certainly older than these collections (the Ford Label can be dated between 1946-1957). This mine dates back to the 1500 era as a copper mine later worked for Tungsten. Many other species were found there in later years including a few fine Torbernites many of the best can be seen in the British Museum. This piece is quite choice.
Bornite pseudo after Chalcocite
Levant Mine, Trewellard, St Just,
5.5 x 4.7 x 2.7 CM (small cabinet/ large miniature)
Very fine classic specimen, ex George Robinson collection with sharp, free standing crystals. This specimen is currently pictured on Mindat it is the first specimen in the St Just Bornite section. The shape of the original Chalcocite shows some cyclic twins that are perfectly preserved. Some of the crystals may still have some Chalcocite inside. The exterior shows the patina of Bornite and is quite attractive. In fine condition as seen a choice old classic piece
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.
