Skutterudite is a steel coloured arsenide cobalt mineral which tends to have a metallic lustre and leaves a black or dark grey streak. It is a rare, dense mineral which can sometimes contain amounts of nickle and iron; it forms by hydrothermal processes in moderate to high temperature environments. Skutterudite can often be found alongside associated minerals such as silver, erythrite, baryte, calcite quartz and many more. These particular samples were collected Bou Azzer District, Morocco and are available in small sizes ( see drop down menu ) and come supplied 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.

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.
