The term Chalcedony covers a wide variety of cryptocrystalline Quartz that presents in a vast array of colours, forms & patterns. Most of which have been given further classification due to the colour & form presented i.e Agate is identified by its banded structure, Carnelian & Chrysoprase by colour, Bloodstone is identified by both colour & patterning, Petrified wood is classified due to its organic form.
Pure or ‘actual Chalcedony’ which carries the gemstone classification is distinguished by translucency, solid lighter colour & lack of banding, usually seen in blue to white or gray.
Chalcedony is compact silica often found in sedimentary & volcanic environments. It forms in cavities & cracks over long periods through slow low temperature (up to 200oc) deposition of silica rich solutions. The result is Quartz finely intergrown with Moganite, both are silicon dioxide minerals, but have different crystal structures Quartz is trigonal & Moganite is monoclinic, together they form Chalcedony. Colours are primarily dictated by intruding minerals such as the presence of iron, nickel or chromium.
