, a red variety of See also:chalcedony, much used as an ornamental See also:- STONE

The old name was cornelian, said to have been given in reference either to the horny See also:appearance of the stone (See also:Lat. See also:cornu, " See also:horn ") or to its resemblance in See also:colour to the See also:berry of the cornel; but the See also:original word was corrupted to carnelian, probably in allusion to its reddish colour (carneus, " flesh-coloured ")

Certain kinds of brown and See also:bright red chalcedony, much resembling carnelian, pass under the name of See also:sard (q.v.)
.
The See also:Hebrew odem was probably a red stone, either carnelian, sard or See also:jasper
.
All carnelian is translucent and is thus distinguished from jasper of similar colour, which is always opaque
.
The red colour of typical carnelian is due to the presence of ferric See also:oxide
.
This is often See also:developed artificially by exposure to See also:sunshine, or to artificial See also:heat, whereby any ferric See also:hydrate in the stone becomes more or less dehydrated; or the stone is treated with a See also:solution of an See also:iron See also:salt, like ferrous sulphate, and then heated, when ferric oxide is formed in the pores of the stone
.
An opaque white See also:surface is sometimes produced artificially on a red carnelian: this is said to be done by coating the stone with carbonate of soda and then placing it on a red-hot iron; or by using a mixture of potash, white See also:lead and certain See also:vegetable juices, and See also:heating it on See also:charcoal
.
See also:Inscriptions and figures in white on red carnelian (" burnt carnelian ") are well known from the See also:East
.
Much carnelian comes from See also:India, being mostly derived from See also:agate-gravels, resulting from the disintegration of the See also:Deccan traps, in the neighbourhood of Ratanpur, near See also:Broach
.
A See also:good See also:deal of the carnelian now sold, however, is Brazilian agate, artificially stained
