Apatite mineral specimens exhibiting a vibrant, electric blue colour, pieces are crystalline in texture and rough with minute amounts of secondary minerals included, these high grade specimens are only available in limited small sized pieces. Apatite is actually the name given to a group of minerals which include hydroxylapatite, fluorapatite and chlorapatite. These particular samples, known simply as blue apatite come from Madagascar, it is a phosphate mineral that has a vitreous lustre, shining slightly when viewed under certain angles of light and gives a white streak, the primary use is in the manufacture of fertilizer due to it being a source of phosphorus, generally it can come in a wide variety of colours and crystal habits, however, these samples are blue in colour with a massive crystalline habit, suitable for collectors, educational use and the like. Specimens will come supplied in a card tray or magnifier box (depending on your chosen option) and come with a small label.

Apatite crystals found in Morocco with a green hue and a semi transparent appearance. These crystals very from 0.5 – 1.5cm and come supplied in a pack of 5 pieces. Specimens are supplied in a small polythene bag with a information label. Apatite is a phosphate mineral that has a vitreous lustre and a white streak but do not show good terminations. Its primary use is in the manufacture of fertiliser due it being a source of phosphorus. Apatite comes in a wide variety of colours and crystal habits, these samples are green in colour with a prismatic crystal habit. Supplied in a polythene bag with an information label.
Calcite rhomb mineral specimens exhibiting excellent rhomic crystal form expected of calcite, the pieces come from Morocco and as expected, will fizz, bubble and release CO2 if the hydrochloric acid test is performed. They are available in 2 colours and will be supplied in a card tray with an information label.
Specimens of Chlorapatite with Phlogopite mica and Enstatite changed to Steatite (talc), found in Ødegärden Mines, Bamble,
Southern Norway. Available in a range of sizes.

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.
Pyrite on Rhaetic Bone Bed collected from Westbury-on-Severn, Gloucestershire. Of our specimens it is the pyrite crystal bed which is the key feature, some specimens may exhibit bones or scales but naturally this is no guarantee

Moss Agate mineral specimens from India, deep green in colour due to the presence of chrome and iron mineral impurities, this chalcedony mineral breaks with a conchoidal fracture, has a glassy texture and can have sharp edges, caution is advised. Available in various sizes, this well known mineral has been used in the past as a gemstone as it takes a high polish, natural specimens, they will come supplied 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.

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.
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.
