Opal is a well known mineral which has been present through out human history, most commonly as an attractive gemstone. It is however, a mineraloid, not a complete mineral, it can contain any where between 3% to 20% water and is deposited at relatively low temperatures in fissures, because of this, it is found in a variety of rocks but the most common and the samples which we stock are opal in limonite. It’s structure allows it to defract light, giving it a schiller effect when held at certain angles, most opal is a vibrant blue colour though colours such as white, red etc have also been found. These particular samples come from Coober Pedy, Australia, a well know opal source, available in various sizes and supplied in a card tray with an information label. Please note these specimens only display a small, patchy surface coating of opal on limonite.

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.
