Chistolite slate is a variation of slate which also contains chiastolite crystals within it,the slate its self is either a brick red or plum colour with the chiastolite crystals appearing as white lines and randomly orientated within the rock matrix. rock specimens are available in various sizes and will be supplied in a labelled card tray.
Kyanite with a black colouration, a rare and unusual variety from Minas Gerais, Brazil, they exhibit excellent high quality radiating sheaths of accicular crystals, starting of from a single point and radiating out into many crystal and becoming wider. The mineral specimens are 3 inches in length with widths and thickness varying from sample to sample, all come supplied in a card tray with a label.

Rhodolite garnets in quartz and mica schist matrix from Southern Norway exhibiting bright vibrant pink coloured garnets in a white quartz and metallic grey mica schist with a start contrast of colours, these minerals specimens are available in 3 sizes and come supplied in a card tray with a 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.
Baryte mineral specimens, unusual samples collected from Foss mine in Scotland, they have a fine crystalline texture instead and are quite robust specimens. Pieces are off white in colour and may show a shimmer effect in certain lighting conditions. Available in various sizes, supplied in a card tray with an information label.

Baryte (also spelt barite) is a widely occurring mineral consisting of barium sulphate, they can occur with many crystal habits, in this case, these mineral specimens exhibit the cockscomb mass form, in which randomly orientated blades of the mineral occur on a massive bed. These particular specimens are a pink or orange colour with a pink bed but other colours of baryte exists, including white, buff or brown. Any barite specimen is incredibly dense, with small pieces even feeling heavier than they appear, which is surprising, considering it is a non metallic mineral. This density was how the mineral obtained its name, being derived from the Greek word ‘βάρυζ’ meaning heavy. It occurs in a range of environments and deposited via many processes including biogenic, hydrothermal and evaporation, among others. Commonly occurring in lead-zinc veins hence some of the samples contain galena (lead sulphide) as well. Over 75% of baryte extracted worldwide is used for weighting driling fluids in oil and gas exploration to control high formation pressures and prevent blowouts. These mineral specimens were mined in Mibladen, Morocco, they are available in various sizes, each specimen is supplied in a labelled card tray.
Orthocalse feldspar mineral specimens from Evje, Norway. It exhibits a pale pink, white or pale grey colouration with excellent cleavage planes with rhombic crystal forms, a common mineral found in granites and rhyolites, orthoclase belongs to the feldspar family of minerals and can be found all over the world. Specimens are available in various sizes and come supplied in a card tray with an information 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.
Sulphur mineral specimens (also spelt sulfur) from Bolivia, these fine crystalline masses give off a pungent odour as expected of this mineral and have a pale yellow colouration to them. They formed in volcanic zones and are excellent for the more serious collector. Available in one size only and supplied in a card tray with a data label.

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.

Iceland spar is a clear variation of calcite, it exhibits the rhombic crystal system of calcite perfectly, the crystals easily divide into rhombs, making them well sought after for a variety of reasons. Originally reported from Helgustadir Mine, Eskifjord, Iceland, hence its name. One of the most remarkable aspect of Iceland spar is its refractive properties. When light passes through one of the crystals, it is divided into two rays at different angles which results in a double refraction effect. Essentially, anything seen though the crystal is seen in double. This can best be seen if you place the calcite over some text, it will appear as if it has been printed twice. These mineral samples come from Santa Eulalia, Chihuahua, Mexico and are available in 2 sizes: Upto 1″ and Over 1″. They come in a card tray with an information 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.
Halite mineral specimens from the Boulby mine in Redcar, North Yorkshire, UK. Halite is a salt mineral and has a cubic crystal system and vitreous lustre, these specimens are rough and available in various sizes, suitable for educational use, supplied in a card tray with a label.
