Jasper is a dense, adulterated selection of silica, habitually red, yellow or brown in color. This stone breaks together with a silky surface, and is worn for decoration or as a precious stone. It can be extremely polished and is utilized for making vases, seals, and at sometimes for even snuff boxes. When the colors are in stripes or bands, it is named as striped or banded type of jasper. Jaspilite is a stripy iron pattern rock that time and again has characteristics of strains of jasper.
It is even written in the Book of Revelation as the following (Refer Revelations 21:11): "It is shined with the glory of the Lord, and its radiance was reminiscent that of a very valuable gemstone, like jasper, that is as clear as crystal."
Jasper can materialize as a solid rock of varying tints of red due to included impurities. Patterns can crop up from the configuration development and from flow outlines in the remains or even volcanic magma ash that was drenched with silica together to form jasper, squashing bands or swirls in the rock.
Types of jasper :
Jasper can appear as an opaque rock of shades of red due to mineral impurities. Patterns can arise from the formation process and from flow patterns in the sediment or volcanic ash that was saturated with silica to form jasper, yielding bands or swirls in the rock.
Jasper may be permeated by dendritic minerals providing the appearance of vegetative growths. The jasper may have been fractured and/or distorted after formation, later rebonding into discontinuous patterns or filling with another material. Heat or environmental factors may have created surface rinds (such as varnish) or interior stresses leading to fracturing.
A brown jasper that occurs as nodules in the Libyan desert and in the Nile valley is known as Egyptian jasper or Egyptian pebble.
Picture jaspers simultaneously exhibit several of these variations (such as banding, flow patterns, dendrites or color variations) resulting in what appear to be scenes or images in a cut section. Spherical flow patterns produce a distinctive orbicular appearance. Complex mixes of impurities produce color variations. Healed fractures produce brecciated jasper. Examples of this can be seen at Llanddwyn Island.
Orbicular jasper or leopard jasper is usually an opaque combination of tan, gray, black or reddish-brown circles or 'spots' of color, hence its name.
