The term jasper is now restricted to opaque quartz, ancient jasper was a stone with considerable transparency, including jade. Ancient jasper was in many cases decidedly green in color, as it is often compared to emeralds and other green objects. Jasper is listed in the Nibelungenlied as bright and green.

Ancient jasper likely contained stones that would now be classified as chalcedony, and emerald-like jasper may have been similar to modern chrysoprase.

The Hebrew word could mean green jasper. Flinders Petrie suggested that the odem, the first stone on the high priest's breastplate, was red jasper, and the minced meat, the tenth stone, could be yellow jasper.

Types of jasper

Chocolate jasper is an opaque rock of almost any color due to the mineral content of the original sediment or ash. The consolidation process creates flow models and sediment models in primary sediments rich in silica or volcanic ash. It is believed that hydrothermal circulation is necessary for the formation of jasper.

Jasper can be modified by diffusion of minerals along the fracture, allowing vegetative growth to occur. The original materials are often broken or distorted after being incorporated into various patterns, which are then filled in with other colored minerals. Airing over time will create highly pigmented superficial skin.
