Mimetite var Campylite
Dry Gill Mine, Caldbeck Fells
6 x 4.8 x 3.7 CM (cabinet)
A cluster of red to brown barrel shaped crystals surrounded by Quartz and a few tiny yellow needles of Mimetite. Classic English specimen this was collected in 1974 by Les Hitchings. Les was a fireman based in Massachusetts, USA who took his work vacations seriously and made several trips to dig in the UK. His label is enclosed. The form is distinct and the condition is good with some small rough areas as seen. A nice example that looks like one of the very old finds.
Light purple Fluorites with penetration twinning on miniature matrix. Vivid Fluorescence which is typical for Fluorite from this region, and some fluorescence in daylight as well. The Fluorites are transparent and have a deeper purple core. Classic habit and in very good condition, these were found for many decades, and are unlike Fluorite from anyplace else.
Super lustrous black Sphalerite crystals on contrasting crystals of Siderite. This piece is from the noted Cornish collection of Lewis Barton (his label is included), and is a superb Sphalerite from anyplace in Cornwall and likely the best known from the Ale and Cakes Mine (which is a great name for a mine)! Despite a few edge nicks and contacts the overall quality and condition is really fine. A choice addition for any good Cornish or UK suite.
A choice old Carn Brea (Cornwall) specimen of Chalcopyrite crystals in Tetrahedral form, well coated with a dark Bornite. Excellent pedigree, previous collections include AK Borland, Brian Lloyd and John Marshall (labels etc included). The matrix is mostly Quartz with some pinkish crystals and some areas of Pyrite. The Chalcopyrites are quite sharp, up to 1.4 CM these are protected in two main vugs so most are in quite good condition. Some minor chipping is noted under loupe inspection, overall displays and looks clean. This mine has long ago vanished but over 100 years ago it produced some great Bornite and Chalcopyrite. A nice specimen from a significant locality in Cornwall.
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.
Heights Mine, Durham, Weardale County
4.1 x 3.3 x 3.3 CM (miniature)
Perfect and well composed Fluorite from the Heights mine. This cute miniature has a prominent, well isolated and very sharp cube perched on top. The edges and corners are sharp and perfect on this, the luster is glasslike and the Fluorites are quite transparent. No visible damage. A good value for a small, choice classic British Fluorite with a quality well beyond typical.
A super impressive and very unusual radiating fan or "wheatsheaf" clustering of chisel terminated Barite. Frizington Barite (or Barytes) is one of the great classics on the mineral world. One of the special features of good Barite from Frizington is their Bicolor nature. On this piece zoned inclusions of Hematite give a red color to edges of the prisms while the core and some terminations are a bright blue. Only some very minor edge wear can be seen and is not evident on display, overall in excellent condition which is impressive for an old classic.
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.
