This is a very nice oval PICASSO JASPER from China...40x30mm...

Jasper is derived from the Greek for "spotted stone". Jasper is usually considered a chalcedony, but put by scientists in a group by itself because of its grainy structure. The finely grained, dense jasper contains up to twenty percent foreign materials that determine its color, streak and appearance. Uniform jasper is rare. It usually is multicolored, striped spotted or flamed.
Some of the most treasured gems are those that show a picture that appears to be taken from nature, called "landscapes". The saturation of the color defines the value. The choice will more often depend on taste for the appearance and composition of the stone.
