Rock crystal is the name given to transparent, clear quartz, so clear are these mineral specimens that they almost look like large chunks of shattered glass. Quartz is the most common mineral found at the surface of the earth and rock crystal is one of the most common, colourless, it is fairly hard and on some of the larger surfaces may show a conchoidal fracture. These specimens are approximately 2″ x 2″ in size and are excellent for collectors and for use in education as it is a major mineral. Supplied in a card tray with an information label.

Quartz crystals from Madagascar, these mineral specimens are small in size, between 3 to 5 cm, as they are A grade, they are completely transparent, crystal clear show the excellent termination of the points and crytsal system. Ideally suited for university level educational use if large numbers are required for students to observe or for serious collectors.
Specimens of Rock Crystal, collected from Madagascar. Rock Crystal is the name for transparent clear quartz. Quartz is the most abundant mineral on the Earth’s surface and a major rock mineral too. These specimens come in lots of 1kg, in a heavy duty polythene bag. Pieces are of various sizes.
Chalcopyrite mineral specimens from Sulitjelma, Norway, a major copper ore mineral, these pieces exhibit excellent quality chalcopyrite detailing the shiny brassy yellow colouration and metallic lustre expected. These mineral specimens are approximately 70% – 80% chalcopyrite and are available in various sizes and come supplied in card tray with an information label.
Massive specular hematite from Brazil, black colouration and metallic lustre which gives the crystals a sparkling appearance. These particular specimens are of specularite crystals in a massive form, therefore the samples have a highly crystalline texture. They come from Brazil and give off a metallic shimmer when held under certain lighting. Available in various sizes and supplied in card tray with an information label.
Magnesite mineral specimens from Greece, the samples are an off white colour and exhibit a somewhat botryoidal texture, formed around ultramafic rocks and metamorphic zones, these specimens are limited and will come supplied in a card tray with a data label.
Galena with massive baryte from Morocco, showing the two contrasting colours of the off white baryte and metallic blue galena mineral specimens together, both are quite dense yet extremely fragile, these samples were collected from Morocco and available in 3 sizes.
Pyrite is a well known and common mineral found around the world, commonly known as fools gold, it has a brassy yellow colour and metallic lustre, most pyrite people will see will likely be pyrite crystal beds or chunks. These specimens are individual cubes of pyrite which demonstrate the signature cubic crystal structure. These samples are from Spain and are available in 2 sizes: 1 cm and 2 cm cubes and come supplied in a polythene bag with an information label.
Cleavelandite is a variety of the mineral albite, one of the constituent minerals of plagioclase feldspar, thus is found in areas where pegmatites and granites exists in certain localities around the world. These particular specimens come from Evje, in Southern Norway and as expected, has a pale green colouration to it. As with albite, cleavelandite also exhibits a triclinic crystal habit and has a hardness of 6- 7 on the Moh’s scale of hardness, it is usually found within cavities of other rocks or minerals. It as named in 1823 by Henry J. Brooke in honor of Parker Cleaveland , professor of geology and mineralogy at Bowdoin College in Maine. Our mineral specimens are massive in form with occasional accessory such as smokey quartz or plagioclase or orthoclase feldspar. The specimens were collected by our own staff from Evje and are available in a range of sizes. Each specimen is supplied in a labelled card tray.

Rhodolite garnets in quartz and mica schist matrix from Southern Norway exhibiting bright vibrant pink coloured garnets in a white quartz and metallic grey mica schist with a start contrast of colours, these minerals specimens are available in 3 sizes and come supplied in a card tray with a label.
Milky quartz mineral specimens from Norway, with a pale white colouration, hence the name, sometimes also known as white quartz, snow quartz or simply quartz. These particular samples were collected by staff from Iveland, Norway. This locality is also where we collected the smokey quartz from. It is in a massive form and has a very fine crystalline texture, this also results in it sometimes being sharp, so caution is advised when handling these samples. It is available in various sizes and supplied in a card tray with an information label.
Sulphur mineral specimens (also spelt sulfur) from Bolivia, these fine crystalline masses give off a pungent odour as expected of this mineral and have a pale yellow colouration to them.
