STONE CHALCEDONY WITH MOTIF "DOG FACE"

STONE CHALCEDONY WITH MOTIF "DOG FACE"

Chalcedony variant has a Mohs hardness between 6-7 scale. General characteristics Jasper is opaque (opaque) and consists of several types, among others PANCAWARNA Jasper, Jasper and Jasper motif Batudarah colored (blue, brown, black and gray). In Indonesia, many variants such as bloodstone and brown jasper. Jasper Brown is in Wajo, South Sulawesi called peroso Ogi or Pyrus bugis because he looked like Pyrus (turquoise)

Brown Jasper, which is often called Peroso Ogi Jasper stone is a type of mineral and sedimentary rocks of volcanic lava formation process chemically closely related to the heating process which can be derived from magmatic processes or intrusion. Jasper chemical properties can be influenced by the chemical composition of the rock before the mutually binding and chemical elements while the inception of rock jasper.

Jasper stone is one variant of chalcedony, classified into siliceous sedimentary stone (the main composition of sedimentary rocks with SiO2), hardness ranging between 6.5-7 on the mohs scale, from 2.88 to 2.89 specific gravity, refractive index of 1.54, micron crystalline structure in the trigonal system. The difference jasper with chalcedony is: jasper stone opaque (opaque) while the translucent chalcedony (transparent) or bias also refract light / like rock wine (translucent).

Jasper stone has a lot of variations of colors, patterns or combinations such as the composition of chalcedony, it is because of the similarity of chemical properties and environments that shape. 

The uniqueness of this stone is a stone Chalcedon one basic color green, and white parts forming the face of dog Lhasa Apso breed originating from Tibet. You are interested in the gemslover ?, please observe and gaze ....
