Molybdenite – Norway £1.00 ex VAT
Specimens of molybdenite in a feldspar matrix from Buskerud in Southern Norway. Molybdenum disulfide (MoS2) otherwise known as Molybdenite is the primary ore of the rare earth metal Molybdenum. This element rarely occurs in pure form in nature and it is from minerals like molybdenite that it can be extracted. The mineral is often formed in hydrothermal veins. In recent years it has become an important factor of alloy production, particularly that of steel and stainless steel. The mineral is similar to Graphite, both in lustre and habit – molybdenite also leaves behind residue when touched (although this is harmless). This interesting property is a result of the molecular structure of the mineral, in which one molybdenum atom is sandwiched between two sulphur atoms, which is repeated in layers, allowing the individual layers to move over each other in the same way a conveyor would. Samples are supplied in a white card tray with an information label. A must have addition to any mineral collection.

Quartz Geode Fragments £1.50 – £6.00 ex VAT
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.
