Natural quartz geodes or nodules found in the Sahara desert, Morocco. These geodes are all lined with sparkling white minute quartz crystals which if set against a dark backdrop, shine brightly. Geodes form as bubbles of gas within magma (the term for lava when the molten rock is still underground). Because of the temperatures difference bwteen the magma and the pocket of gas, the crystals form slower, crystals which form slower tend to form in larger sizes and so with a geode, you have an outside which is made up of very fined grained crystals, too small to see and the inside, which is full of larger crystals. These geodes are slowly becoming harder to obtain as the collectors struggle to get to the site which is littered with old exposive mines from a previous war and when the geodes were stock-piled puff adders set – up home amongst them. These specimens are available in various sizes as geode fragments and come supplied in a card tray with information label.

Specimens of Quartz Geodes, collected from the Sahara Desert, Morocco. These specimens are the fragments of geodes with a quartz lining. Geodes form as pockets of air in magma, when temperature differences result in a slower rate of cooling and thus larger crystals inside the pocket. Specimens come in lots of 1kg, in a heavy duty polythene bag. Pieces are of various sizes.
Rock crystal beds of short quartz crystal points, these mineral specimens come from Durham, UK and are quite popular as are most British minerals, each sample is semi transparent and on a matrix. Samples are supplied in a white card tray with an information label. .

Chalcedony mineral specimens from Morocco, the pieces belong to the quartz family of minerals and is very similar to carnelian, even having a waxy lustre, although it tends to have a botryoidal crystal habit. The pieces are blue, white, red and orange and available in various sizes, 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. They formed in volcanic zones and are excellent for the more serious collector. Available in one size only and supplied in a card tray with a data 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.
Halite mineral specimens from the Boulby mine in Redcar, North Yorkshire, UK. Halite is a salt mineral and has a cubic crystal system and vitreous lustre, these specimens are rough and available in various sizes, suitable for educational use, supplied in a card tray with a 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.
Gypsum satin spar mineral specimens from Morocco, which are a pearly white colour composed of high quality fibrous crystals which are long and orientated in the same direction giving the samples a silky lustre. These pieces are available in various optional sizes, supplied in a card tray with a label.

Orthocalse feldspar mineral specimens from Evje, Norway. It exhibits a pale pink, white or pale grey colouration with excellent cleavage planes with rhombic crystal forms, a common mineral found in granites and rhyolites, orthoclase belongs to the feldspar family of minerals and can be found all over the world. Specimens are available in various sizes and come supplied in a card tray with an information label.
