Specimens of pale blue chalcedony with quartz from Alabaster Coast, Normandy, France. 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. These samples of chalcedony have a predominantly pale blue colouration with some inclusions of white and pale red material, some pieces also contain quartz crystal beds. These specimens are supplied in a white card tray with an information label.
