An opaque variety of Chalcedony, usually red, brown or yellow and coloured by oxides of iron. It has been long used for jewelry and ornamentation. Jasper is common and widely distributed, occurring chiefly as veinlets, concretions, and replacements in sedimentary and metamorphic rocks, as in the Urals, North Africa, Sicily, Germany, and elsewhere. Jasper is number 6.5 to 7 on the Mohs’ hardness scale.
