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
All measurements taken at the widest points

Fluorite crystal beds on a matrix from the famous Weardale locality in County Durham, UK, specimens exhibit a range of colours from rich greens, to deep purples, calming yellows and crystal clear samples, available in a variety of sizes. These mineral specimens are ideal for collectors, children and educational use, supplied in a card tray with a data label.
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.
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.

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.
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.
Dolomite crystal beds, pink in colour form Morocco, the presence of manganese results in a pale pink hue, these mineral specimens also have larger crystals than the UK material and are higher quality. Available in various optional sizes, supplied in tray with a data 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.
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.
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.

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.

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.
These particular samples are a milky white to pale yellow colour and show typical fibrous crystal habit expected from Witherite. Samples are supplied in a white card 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.
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.
