Lepidolite mica mineral specimens which are members of the mica group of minerals, specimens tend to have a lilac colouration, however, grey and rose are also colours which the mineral can be found in. It is often found in granitic rocks such as pegmatites as well as quartz veins, greisens and granites in general, where high temperatures are present. It’s lilac purple colouration have resulted in it being sought after as a gemstone in modern times, however, it is chemicallly important for modern technology as it is a secondary source of lithium, which is the main element present in almost all rechargeable batteries today such as phone batteries, tablets, controllers and more. It is also a major sources of the rare alkaline metals caesium and rubidium which are respectively used in various electrical components, accurate clocks, oil drilling, fireworks and more.
These particular mineral specimens of lepidolite mica exhibit a botryoidal crystal habit, in which the fine crystals have grown to appear as a ‘bubbling’ mass. The surface is smooth and is purple in colour. They come from Minas Gerais, Brazil and each specimen will be supplied in a 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.
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.
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.
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.

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.

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.
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.

Pyrite on Rhaetic Bone Bed collected from Westbury-on-Severn, Gloucestershire. Of our specimens it is the pyrite crystal bed which is the key feature, some specimens may exhibit bones or scales but naturally this is no guarantee

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.
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.
Desert rose mineral specimens composed from gypsum found in Tunisia, the samples are composed of numerous crystals which resemble ‘petals’ which are randomly orientated, thus giving them a rose flower effect. Specimens are supplied in a 1.5″ x 1.5″ card tray or as approximately 1 cm diameter pieces in 1″ magnifier boxes 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.
