E91AC7: Cumbria, British Museum, Baryte, these are all names that remind me of a splendid past. Jordi bought this one from the Behier collection but did not put it up on the web site as the base has a small ding. But given that you cannot see this defect when you display it and that it is such a nice specimen that displays well I think that it would look good in any collection.
As well as the history I like the fact that it has its old labels and that not only are the crystals transparent but that they have two colors, due, Jordi tells me, to the Hematite inclusions in certain areas which add the red tint.

Worth noting is the rarity of this association and the fact that it comes from a classic locality. An uncommon specimen.

Polberro Mines is a small historic mine located in the Saint Agnes area, within one of Cornwall’s classic mining districts. It belongs to the network of workings developed along the St Agnes vein system, known for tin and copper mineralization and for a wide variety of well-crystallized secondary species.

Geologically, the mineralization is related to hydrothermal systems associated with the Hercynian granitic intrusions of Cornwall. The veins, typically trending E–W, are hosted in metasedimentary and granitic rocks, with a typical paragenesis including Cassiterite, Chalcopyrite and other sulfides, accompanied by secondary minerals formed in oxidation zones.

Nentsberry Haggs Mine is part of the historic Alston Moor mining district within the classic North Pennines Orefield, renowned for its stratabound sulphide–carbonate vein systems. Low- to medium-temperature hydrothermal circulation produced veins rich in Fluorite, Baryte, Galena and Siderite, with localized zones exceptionally rich in Witherite. The mine ranks among the world’s most iconic sources of well-crystallized Witherite.

The Rampgill Mine is An important historic lead mine located in the Nenthead mining district, one of the classic mining areas of northern England. Active since at least the 18th century, it was one of the most extensive and productive mines in the region, developed along major veins such as the Rampgill vein and related structures.

Geologically, the mineralization is hosted in Carboniferous rocks, mainly within the ‘Great Limestone’, one of the most mineralized horizons of the Alston Moor orefield. These rocks are cut by a network of mineralized faults with dominant ENE–WSW and NNW–SSE trends, controlling the development of veins and replacement bodies (‘flats’) in the limestone host rocks.
The paragenesis is complex and characteristic: early cavity formation was followed by Quartz and Sphalerite, then Fluorite and Galena, and later by barium and carbonate minerals such as Baryte, Witherite and Barytocalcite, with widespread replacement processes and pseudomorphs between these species.

Accompanied by crystalline masses of Calcite, in strong color contrast, this piece is very representative for the deposit, in addition to having a considerable size.

Smallcleugh is a classic mine of the North Pennines Orefield, a major hydrothermal vein district with lead–zinc mineralization, well known for Galena and Sphalerite specimens, associated with Calcite, Ankerite and, more rarely, Quartz.
Smallcleugh Mine, Blacklocks crosscut, Nenthead mines area, Nenthead, Alston Moor mining district, North Pennines Orefield, former Cumberland, Cumbria  England / United Kingdom

Specimen size: 12.2 × 7.2 × 7.0 cm = 4.80” × 2.83” × 2.76”

Main crystal size: 1.3 × 1.1 cm = 0.51” × 0.43”

TJB56AQ0: Druse of Calcite crystals, clearly pseudomorphs after Baryte, of which it has preserved the dominant forms of the pinacoid and one of the prisms and forming translucent parallel growths.
Comes from the old collection of Robert-Auguste Touchon. Analytical results show it to be simply Baryte partially covered by Calcite, and not Alstonite or Barytocalcite.
Nenthead, Alston Moor mining district, North Pennines Orefield, former Cumberland, Cumbria  England / United Kingdom

Specimen size: 7.4 × 4.6 × 4.4 cm = 2.91” × 1.81” × 1.73”

Main crystal size: 1.4 × 0.9 cm = 0.55” × 0.35”

TA91AJ4: Rosette growths of lenticular Barytocalcite crystals with curved edges. They are on a matrix with gray, very sharp lenticular Calcite crystals. The Barytocalcite has a white color and appears as pseudomorphs or perimorphs coating old Baryte crystals.
The sample, an English classic, is from the John H. Marshall Jr. collection (num. 536), whose card and label, and with a previous label of the Lindsday Greenbank collection, both of which we will send to the buyer. We will also send a copy of the analysis that disproves the wrong perception of Lindsay and John that the white crystals are Witherite when they are really Barytocalcite.
Nentsberry Haggs Mine, Nent Valley, Alston Moor mining district, North Pennines Orefield, former Cumberland, Cumbria  England / United Kingdom

Specimen size: 10 × 7.4 × 4.7 cm = 3.94” × 2.91” × 1.85”

EMT72AQ1: Druse of snow-white, twinned Alstonite crystals (pseudohexagonal bipyramidal twin), on matrix, with white lenticular Dolomite crystals.
An English classic that comes from the Moutet collection (Marseille) where it had been mistakenly identified as Witherite.
It has been analyzed and we will send a copy of the analysis to the buyer.

St Peter's Mine, Sparty Lea, East Allendale, North Pennines, Northumberland  England / United Kingdom

Specimen size: 20.2 × 15 × 7.4 cm = 7.95” × 5.91” × 2.91”

Main crystal size: 4.8 × 3.7 cm = 1.89” × 1.46”

TTA81XXX: Group of pale yellow-greenish cubic Fluorite crystals, partially coated by small Quartz crystals and accompanied by Pyrite crystals. Although the Fluorite–Quartz–Pyrite association is relatively common at the Cambokeels Mine, the main interest of the specimen lies in the presence of black Cronstedtite coatings, especially visible on one of the lateral areas of the piece. This association is much less common and provides an unusual aesthetic and mineralogical contrast.

Geologically, the Fluorite, Quartz and Pyrite formed during the main hydrothermal episodes of the deposit. The Cronstedtite corresponds to a later iron-rich phase, developed locally on the surface of the pre-existing crystals, generating the characteristic dark coatings visible on the specimen.

Main crystal size: 1.8 × 1.8 cm = 0.71” × 0.71”

TCD44XXX: Floating group of cubic Fluorite crystals, very complete and with no noticeable damage. Particularly noteworthy are their bluish-green colour and the remarkable transparency of many of the crystals, with bright and well-defined faces.
This is an old specimen, from July 1997, which belonged to George J. Wilson and was later acquired by Harry Critchley.
A particularly attractive feature of the specimen is its intense fluorescence, accompanied by a marked colour change, perceptible even under different daylight conditions, a characteristic highly appreciated in Fluorites from this locality.

Geologically, these Fluorites crystallized from fluorine-rich hydrothermal fluids that circulated through fractures developed in the Carboniferous limestones of Weardale.
Eastgate Quarry (Blue Circle Cement Quarry), Diana pocket, Eastgate, Stanhope, Weardale, North Pennines Orefield, County Durham  England / United Kingdom (07/1997)

VF92AE7: Great druse of very sharp cubic crystals that are translucent, rich with inclusions and have a very intense and deep violet color.
The sample, an English classic, is from the A. Mayor collection (number 118) and it was acquired from Jesús Talabán, in Madrid, in 1978.
Blackdene Mine, Ireshopeburn, Weardale, North Pennines Orefield, County Durham  England / United Kingdom

Specimen size: 21.3 × 16.2 × 5 cm = 8.39” × 6.38” × 1.97”

Main crystal size: 4.5 × 4 cm = 1.77” × 1.57”

EA29Y8: Group of cubo-octahedral crystals with very well defined faces and edges and showing polycrystalline growths on the surfaces. They are on a matrix of Quartz crystals and partially coated by micro-crystalline aggregates of this same mineral. An excellent English classic, from a very well-known locality.
Blackdene Mine, Ireshopeburn, Weardale, North Pennines Orefield, County Durham  England / United Kingdom

Specimen size: 5.3 × 4 × 4.5 cm = 2.09” × 1.57” × 1.77”

Main crystal size: 3.6 × 3.3 cm = 1.42” × 1.30”

T62QB2: Out of the past came this extremely fluorescent English Fluorite, in this case very well placed on its Quartz matrix.
Frazer's Hush Mine, Rookhope District, Weardale, North Pennines Orefield, County Durham  England / United Kingdom

Specimen size: 6.5 × 8 cm = 2.56” × 3.15”

ME91D8: From all the Fluorite found at Frazer’s Hush we have picked this one for its beauty, perfection, brilliance, and above all for the excellent position of its very aerial crystals that contrast well with the white Quartz matrix. As with all the material from this mine the color and fluorescence (slightly visible even without sunlight) is great. A fine classic.
Frazer's Hush Mine, Rookhope District, Weardale, North Pennines Orefield, County Durham  England / United Kingdom (1994)

EQL86AP0: Very aerial growth of Fluorite crystals, between transparent and translucent, with good luster and an intense color, very rich in inclusions. On a matrix of Galena crystals with very marked skeletal shapes reminiscent of some French galenas from Les Malines whose habit is locally called 'tricotées' (knitted)
Very original and different from others in this locality.
Frazer's Hush Mine, Rookhope District, Weardale, North Pennines Orefield, County Durham  England / United Kingdom

Specimen size: 11.6 × 9.2 × 4.6  cm = 4.57” × 3.62” × 1.81”

Main crystal size: 3.3 × 2.4 cm = 1.30” × 0.94”

TAM88XXX: Very well-defined cubic crystals of Fluorite, some of them twinned, lustrous and violet in color, with marked color zoning, more intense towards the center of the crystal and lighter towards the edges.
It comes from a classic English mine that was worked for lead during the 19th century and that, in the 1970s, also produced Fluorite.
Burtree Pasture Mine, Cowshill, Weardale, North Pennines Orefield, County Durham  England / United Kingdom

Specimen size: 8.5 × 6.8 × 3.4 cm = 3.35” × 2.68” × 1.34”

Main crystal size: 2.5 × 1.5 cm = 0.98” × 0.59”

TRM32XXX: Fluorite crystals on a Siderite matrix that has acquired an intense reddish colour as a result of oxidation. The matrix displays cavities and dissolution features that appear to correspond to former crystals, probably of a carbonate, now completely dissolved, whose arrangement suggests an epitactic growth relationship with the Siderite.
The contrast between the lilac Fluorite, with its paler zones, and the altered Siderite gives the specimen a very distinctive appearance.

Geologically, Greenlaws Mine forms part of the hydrothermal vein system of the North Pennines Orefield, hosted by Carboniferous carbonate and clastic rocks. The association of Fluorite and Siderite reflects a fluorine- and carbonate-rich hydrothermal stage, followed by oxidation processes that partly modified the matrix and produced its present reddish colours.
Greenlaws Mine, first level East flats, 250ft, Daddry Shield, Weardale, North Pennines Orefield, County Durham  England / United Kingdom

Specimen size: 9.4 × 8.7 × 2.8 cm = 3.70” × 3.43” × 1.10”

Main crystal size: 2.1 × 2 cm = 0.83” × 0.79”

TD27T1: A fine group, on matrix, of “Jackstraw” type crystals, colored by an unidentified and not analyzed salt of copper.
The sample is with a label from Bentley’s Minerals that we’ll send to the buyer.
Redburn Mine, Rookhope, Weardale, North Pennines Orefield, County Durham  England / United Kingdom

Specimen size: 3.7 × 2.8 × 2.2 cm = 1.46” × 1.10” × 0.87”

Main crystal size: 1.8 × 0.3 cm = 0.71” × 0.12”

VG68Z4: Cubo-octahedral Galena crystal showing an equal development of the cube and the octahedron faces. One of the cube faces is coated by a grayish-yellow Pyrite crust and the crystal is with white small Fluorite crystals. The Galena crystal is very well defined, more so than usual in the samples from this area.
Weardale, North Pennines Orefield, County Durham  England / United Kingdom

Specimen size: 5.2 × 4 × 3.8 cm = 2.05” × 1.57” × 1.50”

Main crystal size: 4.4 × 3.2 cm = 1.73” × 1.26”

TXM61XXX: A group of light violet Fluorite crystals, well arranged on the matrix and displaying a particularly attractive luminosity. The crystals show well-defined faces and form a balanced group, leaving part of the Galena matrix visible and partially covered by abundant Cerussite crystals. Although the Cerussite occurs as small crystals, its presence is notable and adds further mineralogical interest to the specimen, which combines an elegant appearance with a delicate color.

The Fluorite and Cerussite formed in the oxidation zone of the deposit. The Cerussite resulted from the alteration of primary lead minerals and is a characteristic association in this type of mineralization, although it does not always occur as abundantly as in this specimen.
Coldstones Quarry, Greenhow, North Yorkshire County, Yorkshire  England / United Kingdom (1992)

Specimen size: 5.8 × 5 × 3.1 cm = 2.28” × 1.97” × 1.22”

Main crystal size: 1.4 × 1.4 cm = 0.55” × 0.55”

TVR7XXX: A group of tabular Baryte crystals almost completely coated by a fine layer of cream-colored Smithsonite crystals, which perfectly preserves the morphology of the original Baryte crystals. Small pale violet Fluorite crystals appear on one side of the specimen.
It is interesting to observe Smithsonite from Coldstones in this habit, coating Baryte crystals, which gives the Smithsonite a certain aesthetic quality, as it usually has an earthy appearance at this locality.

The Smithsonite formed in the oxidation zone of the deposit through the alteration of primary zinc minerals, whereas the Baryte and Fluorite belong to the original hydrothermal mineralization.
Coldstones Quarry, Greenhow, North Yorkshire County, Yorkshire  England / United Kingdom

Specimen size: 6.4 × 4.4 × 2.8 cm = 2.52” × 1.73” × 1.10”

TFG170XXX: A group of cubic Pyrite crystals, of good size for the locality, lustrous and with well-defined faces. The specimen stands out for the excellent preservation of the crystals, better than is usually seen in specimens of this type from the Hilston beaches.

Geologically, Pyrite formed by precipitation from iron- and sulfur-rich fluids during the diagenesis of marine sediments. Subsequent erosion of the Holderness coastal cliffs released these mineralized nodules.
Hilston beaches, Holderness, East Riding of Yorkshire, Yorkshire  England / United Kingdom

Specimen size: 6.8 × 6.7 × 4.6 cm = 2.68” × 2.64” × 1.81”

Main crystal size: 2.5 × 2 cm = 0.98” × 0.79”

TRB72XXX: Group of good-quality Goethite crystals, clearly superior to those usually found at this quarry, partially covering a matrix of Quartz crystals with Calcite. It comes from two British collections, first that of Graham Morse and later that of Harry Critchley, a provenance that adds historical significance to the specimen.

Geologically, Whatley Quarry exploits a thick succession of Lower Carboniferous limestones in the Mendip Hills. The mineralization occurs in fractures and cavities within the limestone, formed and reactivated during the Variscan deformation. Goethite is a secondary mineral, whereas the Quartz crystallized in cavities associated with the circulation of low-temperature hydrothermal fluids.
Whatley Quarry, Mendip Hills, Whatley, Somerset, South West England  England / United Kingdom (03/1998)

Specimen size: 6.3 × 4.4 × 2.9 cm = 2.48” × 1.73” × 1.14”

HM180EF: Columnar aggregates of Mendipite, a rare lead chloride, light in color with yellowish and pale pink hues. On matrix, with Galena.
The specimen comes from the area of the type locality for the species and as we normally do in these cases we will send the buyer a copy of the analysis.
Torr Works Quarry (Merehead Quarry), Cranmore, District Mendip, Somerset, South West England  England / United Kingdom

Specimen size: 3.8 × 2.2 × 1.6 cm = 1.50” × 0.87” × 0.63”

TRM96AO3: Microcrystalline aggregates of the rare Mereheadite, a lead halide with borate and carbonate ions. They are lustrous, a uniform deep yellow in color, and are associated with Mendipite, another rare white lead halide. On matrix, with Calcite and centered aggregates of acicular crystals (apparently Coronadite)
Excellent UK classic from the type locality for both species.
Torr Works Quarry (Merehead Quarry), Cranmore, District Mendip, Somerset, South West England  England / United Kingdom

Specimen size: 5.8 × 4.6 × 2.4 cm = 2.28” × 1.81” × 0.94”

Main crystal size: 0.8 × 0.1 cm = 0.31” × 0.04”

TFF12XXX: Specimen in which the excellent state of preservation of the Pyrite and Calcite stands out, both with good luster and without visible damage. The Pyrite forms aggregates of crystals partially covered by white Calcite crystals. On the surface of the Pyrite, small Sphalerite crystals are present, adding interest to the specimen.

From a geological point of view, this type of association is characteristic of sedimentary and diagenetic environments in Jurassic limestones, where fluids rich in iron, sulfur and, sometimes, zinc precipitate sulfides such as Pyrite and Sphalerite, later accompanied by carbonates such as Calcite.

Hampstead Quarry is located in the Cotswolds area, known for its outcrops of Jurassic limestones (mainly Lower and Middle), with typical oolitic facies. These limestones may show cavities and fractures where secondary mineralizations develop, mainly carbonates and sulphur and iron oxides, within a shallow marine sedimentary context.
Hampstead Quarry, Hampstead, Cotswold District, Gloucestershire  England / United Kingdom

Specimen size: 6.8 × 5.7 × 2.4 cm = 2.68” × 2.24” × 0.94”

Main crystal size: 1.5 × 0.9 cm = 0.59” × 0.35”

TAB48XXX: Two groups of Baryte crystals, one of them forming a rosette aggregate of cream color and the other a fibrous-radial aggregate, possibly replacing a fossil shell and preserving its original structure, with the terminations being more whitish. They are on a matrix of very fine-grained clayey rock, whitish, completely covered by cream-colored Calcite crystals of a darker tone and lustrous, partially coating a botryoidal aggregate with another possible fossil shell.

Warden Bay is a coastal area known for its Eocene clay cliffs (London Clay Formation), rich in fossils and concretions. It is a classic locality for the occurrence of Baryte and Pyrite nodules and crystals, formed under reducing sedimentary conditions, often associated with organic remains.
