The Borrowdale Graphite deposit is located at Seathwaite in the Borrowdale valley, in Cumbria. This occurrence is unique in the UK and it is one of only two graphite vein deposits hosted by volcanic rocks worldwide — the other is in southern Spain. At Seathwaite, the graphite occurs in a set of mineralised faults hosted by andesite lavas and sills belonging to the 450 million year old (Ordovician) Borrowdale Volcanic Group. Narrow veins filling fault fissures contain massive graphite and chlorite, but the richest deposits containing nodules of graphite, altered wall rock and brecciated quartz are in pipe-like bodies developed at the intersections of faults. Often referred to as Plumbago or Wad. Samples were collected many years ago.

Specimens of Bituminous Coal, collected from the Carboniferous deposits in Yorkshire. Bituminous Coal is an organic sedimentary rock, that forms by diagenetic and sub metamorphic compression of peat bog & swamp material. Its primary constituents are macerals: vitrinite, and liptinite. The carbon content of bituminous coal is around 60-80%. The rest consists of residual water, air, hydrogen, and sulphur. These specimens are available in multiple sizes and come in a white card tray with an information label.
We also supply Bituminous Coal thin sections for microscope study which are available to buy HERE.
Graphite mineral specimens from China, well known in the modern day as the ‘lead’ in pencils due to its non toxic chemical composition, these samples of graphite are soft, exhibit a metallic lustre, dull grey colouration and waxy/greasy texture. Available in various sizes they come in card trays with a label.
Moss Agate mineral specimens from India, deep green in colour due to the presence of chrome and iron mineral impurities, this chalcedony mineral breaks with a conchoidal fracture, has a glassy texture and can have sharp edges, caution is advised. Available in various sizes, this well known mineral has been used in the past as a gemstone as it takes a high polish, natural specimens, they will come supplied in a card tray with an information label.
Specular Hematite, also known as specularite is a variation of haematite which has a silver or black colouration and metallic lustre which gives the crystals a sparkling appearance. These particular specimens are of specularite crystals with an anhedral form on a massive haematite matrix. These specimens display veins of specularite within a matrix of massive haematite. They come from Cumbria, UK and are available in various sizes, each sample comes supplied in a card tray with an information label. They would be of particular interest to those who are particular keen on collecting British mineral specimens.
Specimens of small almandine garnets found in India. These specimens are supplied in a small white card tray with an information label. The specimens are approximately 1″ – 1.5″ cm in diameter though this will vary slightly.

Chalcedony mineral specimens from Morocco, the pieces belong to the quartz family of minerals and is very similar to carnelian, even having a waxy lustre, although it tends to have a botryoidal crystal habit. The pieces are blue, white, red and orange and available in various sizes, supplied in a card tray with an information label.
Blue lace agate mineral specimens of moderate size which clearly exhibit alternating bands of blue and white, the specimens come from Botswana and are excellent grade with minimal matrix on them. Formed through volcanic processes and the deposition of silica compounds in igneous rocks, these minerals are both important educationally and calming to look at.

Baryte mineral specimens collected form Somerset in the UK, exhibiting a bladed crystal habit or massive form, the dense specimens are an off white, yellow or brown colour due to staining from hematite (iron ore), available in various sizes, ideal for educational use.
Specimens of Salt Pseudomorphs on a limy matrix, collected from the Triassic Aust Cliff in Avon, UK. Salt Pseudomorphs serve as important inicators of paleoenvironmental conditions. They typically form in semi arid (dry) climates, where saline water evaporates, which leaves behind cubic salt crystals. These salt crystals later dissolve, occasionally preserving their cubic imprints These specimens are available in multiple sizes and come supplied in a white card tray with an information label.

Cut ulexite mineral specimens from California, USA. A mineral similar to gypsum, ulexite is able to transmit light through its long axis, meaning if placed above an image or text, will transmit it to the samples surface as an image. Hence the name TV rock, excellent for children, these pieces are available in several sizes and will come supplied in a card tray with an information label.
Specimens of white coloured Plagioclase Feldspar also known as a Albite-Anorthite Series mineral. The specimens come from Osedalen, Southern Norway and are supplied in a 2″x2″ 3″x2″ 4″x3″ card tray with an information label.
Magnesite mineral specimens from Greece, the samples are an off white colour and exhibit a somewhat botryoidal texture, formed around ultramafic rocks and metamorphic zones, these specimens are limited and will come supplied in a card tray with a data label.
Cleavelandite is a variety of the mineral albite, one of the constituent minerals of plagioclase feldspar, thus is found in areas where pegmatites and granites exists in certain localities around the world. These particular specimens come from Evje, in Southern Norway and as expected, has a pale green colouration to it. As with albite, cleavelandite also exhibits a triclinic crystal habit and has a hardness of 6- 7 on the Moh’s scale of hardness, it is usually found within cavities of other rocks or minerals. It as named in 1823 by Henry J. Brooke in honor of Parker Cleaveland , professor of geology and mineralogy at Bowdoin College in Maine. Our mineral specimens are massive in form with occasional accessory such as smokey quartz or plagioclase or orthoclase feldspar. The specimens were collected by our own staff from Evje and are available in a range of sizes. Each specimen is supplied in a labelled card tray.
