Gems, Precious Stones, Precious Metals - Jasper Jasper - Gem Color 9 - #D73B3E
Jasper, a form of chalcedony, is an opaque, impure variety of silica, usually
red, yellow, brown or green in color; and rarely blue. This mineral breaks with
a smooth surface, and is used for ornamentation or as a gemstone. It can be
highly polished and is used for vases, seals, and at one time for snuff boxes.
When the colors are in stripes or bands, it is called striped or banded jasper.
Jaspilite is a banded iron formation rock that often has distinctive bands of
jasper. Jasper is basically chert which owes its red color to iron inclusions.
The jasper is one of the traditional birthstones for March.
