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.

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.

Plagioclase Feldspar and Talc specimen from Otta in Southern Norway. Feldspar is the most abundant mineral in Earth’s crust, comprising over 40% of the total estimated mass. This variety, Plagioclase is the Sodium/Calcium rich variety of Feldspar, providing a pale pink colour. Talc is another abundant mineral, notably it is the index mineral for number 1 on Moh’s hardness scale – which means it is one of the least scratch resistance minerals on Earth; it is extremely friable and can leave a smooth, dusty trail on your hands once touched – this is not dangerous and is actually good for your skin! This specimen is perfect for laboratory or classroom analysis, as it shows the symbiosis of 2 abundant and siginificant silicate minerals in one specimen. Also ideal for a collection revolving round Norwegian minerals or silicates. Each specimen is provided with a white card tray and information label.
Specimens of Fluorescent Apatite, collected from Madagascar. Whilst under normal lighting, these specimens are blue in colour and exhibit a massive form with crystalline texture. When exposed to shortwave UV lighting, they fluoresce in a variety of colours, including yellow, orange, blue, green or even pink. These specimens measure approximately 1.5 – 2 inches in size and come in a white card tray with an information label.
Fluorescent aragonite mineral specimens from Morocco, this white variation has excellent colouration when exposed to short wave UV lighting, it becomes another worldy green colour, the specimen is only enhance by the aragonite crystals botryoidal crystal forms. Supplied in 2″ x 2″ size only, the samples will come in a card tray with an information label.
Calcite rhombs are the massive forms of calcite crystals, exhibiting the rhombic (cubic) crystal nature excellently. These mineral specimens from Morocco also display excellent fluorescent properties, while viewed under natural lighting, they rhombs are a pale off white colour, however, when viewed under short wave UV lighting, they fluoresce an extraordinary, vivid pink and red colour, the complete opposite of what you would expect. Supplied as 2″ x 2″ pieces in a card tray with a data label.
Fluorescent cerussite specimens from Mibladen, Morocco. The samples are a perfect addition to any mineral collection and come supplied in a 1.5″ x 1.5″ white card tray with an information label.

Specimens of Fluorescent Chalcedony Nodules, collected from Morocco. This mineral belongs to the quartz family and is very similar to carnelian, even having a waxy lustre, although it tends to have a botryoidal crystal habit. These particular samples are fluorescent under shortwave UV light and display a bright orange/yellow colouration. They range from 1.5 – 2 inches approximately and come in a white card tray with an information label.
Specimens of Fluorescent Chiastolite, collected from Cumbria, UK. These specimens are of Chiastolite Slate and display white chiastolite crystals within a rock matrix. Chiastolite is a variation of the mineral andalusite. Under exposure to shortwave UV light, these chiastolite crystals fluoresce a white colour. These specimens measure 2 – 3″ approximately and will feature several randomly orientated chiastolite crystals within a matrix. Specimens come in a white card tray with an information label.
