Quartz on Hematite with Dolomite - classic English
stock #23.1-647
Florence Mine, Egremont
Cumberland, Cumbria, England
5.1 x 4.5 x 3.2 CM (miniature)
price: $320
Pre Tucson

From the historic Iron mining region of Egremont in the Cumberland region this is a choice combination specimen. The Hematite matrix has two main generations showing, the older, inner, is a botryoidal red Hematite while the newer is a sparkling crystalized black layer. Perched on the Hematites are several smoky Quartz crystals the largest just under 3 CM. A sprinkling of saddle-shaped Dolomite crystals adds a nice contrast. The is sharp, very lustrous and undamaged, the largest crystal has contacts on one side but no chipping or nicks. Old and classic, this from the last Iron Mine to work in England.

SOLD Fluorite with Hematite, Dolomite, Baryte
stock #SOLD 19.1-906
Ullcoats Mine, Egremont, Copeland
Cumberland, Cumbria, England
6.3 x 3.8 x 3.6 CM (cabinet)
price: $0
Pre Tucson

Very lustrous blue cubes of Fluorite on a light color matrix. The host rock is a mix of Dolomite and Barite with very tiny bits of Hematite in a few spots. The crystals are remarkably sharp and vivid, some show zoning especially distinctly when examined under magnification. England is famed for its many diverse Fluorites but such bright blue color is quite unusual from this region. Sharp small crystals and in fine condition.

Chalcophyllite, Cornubite, Cornwallite, Cuprite and Liskeardite? Cornish classic.
stock #20.1-342
Penberthy Croft Mine, St. Hillary
Cornwall, England
4.2 x 3 x 2.1 CM (small miniature/ large thumbnail (toenail))
price: $300
Pre Tucson

A lot of species on this small specimen! The matrix here has a few small Cuprite crystals on the edges but the main open vug is packed with crystals of colorful Copper secondary minerals. The Chalcophyllite is most prominent with well-defined crystals in classic habit. It is quite rich for this locality. This is a very old mine, closed in 1840. An attractive piece though small, the Cornubite and Cornwallite are visually rather similar both in botryoidal zones and some very tiny druses, we are copying earlier labels and using previous owners checking to include both species on our listing, but we have not done further testing. There may be other species present as well, it is a densely populated specimen! I am unsure about the Liskardite, it is supposed to be there but the only spots I can find with magnification that may be this specie are very hard to see well. If present it is a very small amount and only listed for completeness. An uncommon Cornish multi-specie piece that is quite colorful.

Botallackite - very rich specimen
stock #22.1-381
Cligga Mine, Cligga Head, Perranporth, Perranzabuloe, St. Agnes District
Cornwall, England
7.8 x 5.9 x 4.7 CM (cabinet)
price: $800
Early summer 2023

A fine and sizable classic Botallackite from Cligga Head (Cornwall) with dense coverings of bright vivid green crystals. A fairly rare Copper Chloride, these crystals are on every side of the matrix. There are two larger flat faces on either side that are nearly solid lustrous Botallackite. Not often seen as display quality specimens (most are micros) this piece has fine impact. Quite big crystals for the specie and on an attractive cabinet sized matrix .

Pyromorphite - classic British
stock #17.1-577
Roughtongill Mine, Caldbeck Fells
Cumberland, Cumbria, England
4.8 x 3.8 x 3.7 CM (miniature)
price: $460
Spring 23

From the Roughtongill Mine this is nearly all Pyromorphite with almost no matrix. A solid crystal mass with two generations the larger crystals are more green, the smaller more yellow. Ex Les Hitchings collection, obtained in 1974 during a collecting trip to the mine with Richard Barstow. A choice piece with crystals to 1.3 CM and in very good condition. The tiny bit of matrix is crystallized Quartz so the specimen is quite heavy and sturdy.

Boracite with Hilgardite and un-named new specie
stock #23.1-330-(D5598)
Boulby Mine, Loftus
North Yorkshire, England
6.4 x 4.6 x 3.8 CM (cabinet)
price: $500
Spring 23

A sparkling small cabinet specimen of Boracite in both mint-green and colorless crystals. Ex University of Delaware Mineral Museum, obtained by them from the Scott Williams collection. Along with the Boracite, the front is scattered with small Hilgardite crystals and the back is almost all Hilgardite. The Scott Williams label notes this was collected on September 1993, and this contains a new, yet to be named, specie, a white Borate mineral. We do not know for certain what that specie is or was at that time but suspect it is the new polytype Hilgardite 3Tc. From the modern classic locality of the Boulby Mine, (England) this is an undamaged and very attractive piece.

Fluorite - classic British, with Sphalerite and Ankerite
stock #15.1-538
Brownley Hill Mine, Nenthead, Alson Moor, Eden
Cumberland, Cumbria, England
10.3 x 7.5 x 5.7 CM (cabinet)
price: $590
Spring 23

Fine old British Fluorite from the Alston Moor area (Brownley Hill Mine). This is both very esthetic in person and unusual for a British Fluorite. The cubes show both zoning and some color difference on different faces. There are some faces that are cloudy and others that are transparent with glassy luster. The interiors seen though the transparent faces show a good yellow-green hue that glows well if backlit. Exceptional condition with very sharp edges and corners, no noticeable damage and well-composed form. There are some small areas of Sphalerite on the underside and Siderite or Ankerite (this mine has both specie and they look similar) on a few crystal faces. We see very few specimens from this early British mine and fewer still are in such fine shape. Several good display angles on this piece, it is a pre 1960 vintage but likely far older. Looks even better in person.

Chalcopyrite with Quartz - classic British
stock #23.FC-012
Redruth
Cornwall, England
6.8 x 4.3 x 2.7 CM (cabinet)
price: $950
Spring 23

A killer Cornish Chalcopyrite! Excellent sharp irridescent Chalcopyrites in several habits mixed with Quartz crystals on a Chalcopyrite matrix. This looks very much like some specimens in the British Museum collection, those did not have any mine attribution, this one however is credited to the Redruth area on an older label. We have never seen anything like this from Redruth but perhaps the community of Cornish collectors have better information on that detail. We are informed that many old specimens with Redruth Labels came in fact from the nearby Carn Brea, this seems a likely possibility. No matter the mine, this has a classic Cornish look, and the crystals are especially bright with fine patina in person. There is one elongated habit Chalcopyrite crystal that is especially fine, this is a habit that is quite rare worldwide. Though Chalcopyrite is a common mineral, fine crystals are surprisingly rare and these are outstanding. Excellent display that is better in person.
