Specimens of Kyanite in Fuchsite, collected from Mundarara Mine, Arusha Region in Tanzania. Kyanite is a distinct silicate mineral with a rich blue colour. Its prescence often indicates a high pressure metamorphic environment. Despite the kyanite in these fuchsite specimens being of a low grade, the distinct blue colour is still visible. These specimens are available in multiple sizes and come 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.

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.
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.
