Jasper is composed of chalcedony, microcrystalline quartz and other minerals that combine to create colorful bands and patterns. The large variety of jasper patterns are used to give the stones their various names. The most popular is landscape jasper so named because of the tiny landscape panoramas that appear thereon. Picture jaspers exhibit combinations of patterns (such as banding from flow or depositional patterns caused by water or wind), and color variations the look like scenes or images on a cut section. There is also orbicular (circular) jasper, and ribbon jasper. See the variety in the stones shown above.
Jasper is found in many countries and used often as architectural adornments on buildings. Perhaps that is because the new Jerusalem descending from heaven is described as follows: “It shone with the glory of God, and its brilliance was like that of a very precious jewel, like a jasper, clear as crystal.” Revelation 21:11.
