Chalcedony is a cryptocrystalline form of silica, comprised of the polymorphs quartz and moganite. Typically, chalcedony has a waxy lustre and a botryoidal (bubbly) appearance, commonly it is blue in colour, but reds, oranges and white are also present, sometimes mixed together. Chalcedony, along with carnelian has been used throughout history as a gemstone, its pearly lustre when polished has seen it used in various pendants, seals and broaches. It was also used much earlier than that as pre-historic tools and implements such as spear and arrow heads due to the conchoidal fracture that chalcedony has, like other quartz minerals, it tends to break similar to glass. Such examples of primitive chalcedony tools have been found as far back as the Bronze age. These specimens of chalcedony come from Morocco, they are mostly opaque and white,black and grey in colour but interestingly some also fluoresce brown or orange when exposed to shortwave UV light. Available in a range of sizes each supplied in a labelled card tray.

Native copper ore mineral specimens from the famous Keweenaw copper deposits of Mitchigan, U.S.A. The specimens have a heavy red-orange metallic specimens with streaks of blue-green oxidation and a wiry crystal habit. Available in a range of sizes.
Specimens of Salt Pseudomorphs on a limy matrix, collected from the Triassic Aust Cliff in Avon, UK. Salt Pseudomorphs serve as important inicators of paleoenvironmental conditions. They typically form in semi arid (dry) climates, where saline water evaporates, which leaves behind cubic salt crystals. These salt crystals later dissolve, occasionally preserving their cubic imprints These specimens are available in multiple sizes and come supplied in a white card tray with an information label.
