Fluorite (also known as fluorspar) crystal beds from the famous British locality, Weardale in County Durham, UK. It is a popular mineral specimen for many, children, teachers, collectors etc, it often forms with a cubic crystal habit with the crystals being a variety of colours and sizes from deep rich purples, vibrant greens, calming yellows and sometimes crystal clear. These particular samples of fluorite crystals on matrix are vary with any of the mentioned colours. The history of fluorspar mining in the region began in 1882 and finally finished in 1999, with the closure of the Frazer Hush Mine. Some good quality specimens are still obtained from Rogerley and Greenlaws mines, but they are purely for the collectors market, often fetching very high prices.

Fluorite (also known as fluorspar) crystal beds with galena collected from Ashover, Derbyshire. Fluorite is a popular mineral specimen for many, children, teachers, collectors etc, it often forms with a cubic crystal habit with the crystals being a variety of colours and sizes from deep rich purples, vibrant greens, calming yellows and sometimes crystal clear. These particular fluorite crystals on matrix vary with any of the mentioned colours above. Some specimens exhibit well developed galena crystals along with the fluorite however it can be less obvious in others. We supply 2″ x 2″, 3″ x 2″ and 4″ x 3″ specimens; each in a card tray with an information label.
Fluorite octahedrons, these crystals specimens display in excellent quality another variation of the minerals, fluorites crystal habits, the octahedron. The crystals each have exactly 8 faces, hence the octahedron name. During formation, if the crystals have four perfect cleavage planes, octahedral shapes are produced. These particular samples come from China, each one is slightly translucent, letting though partial light and they all vary slightly in colour through various shades of green, purple and clear. It is important to note that these crystals, are genuine fluorite, they have been broken down, using the minerals own habit into the octahedron form. We offer them in two sizes small and large with each coming in a polythene bag with a label.
Small: Approximately 1 – 1.5cm
Large: 2+ cm

Milky quartz mineral specimens from Norway, with a pale white colouration, hence the name, sometimes also known as white quartz, snow quartz or simply quartz. These particular samples were collected by staff from Iveland, Norway. This locality is also where we collected the smokey quartz from. It is in a massive form and has a very fine crystalline texture, this also results in it sometimes being sharp, so caution is advised when handling these samples. It is available in various sizes and supplied in a card tray with an information label.
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.

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.
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.
Galena with massive baryte from Morocco, showing the two contrasting colours of the off white baryte and metallic blue galena mineral specimens together, both are quite dense yet extremely fragile, these samples were collected from Morocco and available in 3 sizes.
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.

Available in 2″ x 2″ size pieces only and supplied in a card tray 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.
Pyrite is a well known and common mineral found around the world, commonly known as fools gold, it has a brassy yellow colour and metallic lustre, most pyrite people will see will likely be pyrite crystal beds or chunks. These specimens are individual cubes of pyrite which demonstrate the signature cubic crystal structure. These samples are from Spain and are available in 2 sizes: 1 cm and 2 cm cubes and come supplied in a polythene bag 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.
