Jasper is a granular, opaque variety of chalcedony (agate also belongs to this family) which is a quartz (SiO2���2) mineral. However, jasper, in addition to or silica, contains an unusually large amount of impurities, mainly iron oxide. It is fine-grained and often strongly marked with orbicular or striped patterns. Red jasper is the most popular gemstone. Yellow, green, and brown colors also exist. These colors may be patchy in nature, several SiO2���2 of them maybe present in the same stone, and they may fade into each other. Iron combinations is the coloring agent for jasper gemstones.For instance iron oxide is responsible for the red color and oxidized ferric iron (ferrous iron) is responsible for green color. Jasper frequently show a well-developed banding. The bands may range from about one tenth of an inch to one inch in thickness. They are straight and parallel rather than concentric (opposite to banded agates). The name jasper is derived from the Greek word for spotted or speckled stone (in another source it is believed that the name jasper is derived from the ancient word iaspis). Green with red spots jasper is the traditional birthstone of March.

Red and white, red and green or red and black are the most pattern encountered. 2- Very rare blue color of jasper is known as false lapis, with reference to the much more beautiful blue gemstone lapis lazuli. 3- Puddingstone is a variety of brecciated or conglomeratic jasper. One type forms when jasper is shattered and broken into many angular fragments. 4- Moss jasper shows a large range of dendritic patterns on the surface of the stone. These are due to manganese staining which has created markings suggesting various plants. 5- Velvety black variety is a very special type of jasper. Ancient people called this type of jasper as Lydian which in modern terminology is referred as basanite. It has been used for thousands of years in testing the colors of the streak of gold alloys in order to determine the gold content.
