Within scheme: South Australian Commodity Codes
A variety of chalcedony colored by iron oxide, which is commonly used as a semi-precious gemstone. The color can vary greatly, ranging from pale orange to an intense almost-black coloration. When Carnelian grades into brown it is known as Sard. Some very dark brown Carnelian can be classified as Jasper. The distinction between these is very fine and relies more on visual appearance than scientific analysis. As a result, it is very possible that one man's Carnelian may be another man's Sard, Agate or Jasper.
