Erythrite mineral specimens exhibiting a vibrant rich crimson pink to blood red colouration, these specimens show clusters erythrite crystal on a rocky matrix, the crystals can be viewed some with the naked eye and some with aid of magnification and show prismatic crystals which appear to have formed within various pockets of the matrix. Erythrite was first described in 1832 from samples found in Grube Daniel, Schneeberg, Saxony. The name is derived from the Greek word erythros, which means red. Historically, it has not been an economically important mineral, but has been associated with deposits of cobalt and native silver, with erythrite sometimes being refered to as ‘red cobalt’. These particular samples come from Bou Azzer, Morocco, with erythrite becoming increasingly rare to obtain, we cannot say how long our stock will last. All specimens are supplied in a card tray with an information label.
Remember to wash your hands immediately after handling erythrite. It is a secondary hydrated cobalt arsenate and is considered toxic. Upon purchase of this particular mineral specimen, you confirm that you are at least 18 years old and that the sample will not be used for any purpose other than collecting or higher educational study or research. This mineral is not suitable for children !

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.
