Rough Large Red Jasper (1,2-1,8Kg)

Jasper is a microcrystalline variety of quartz (chalcedony), which contains inclusions of other materials, such as hematite and goethite, which give it opacity and color. It is formed from the deposition of waters with high levels of silica at low temperatures. These waters are filtered through rocks and this is how other materials are incorporated during the process. There is a great variety of colors and patterns in jaspers, although they are usually found in red, yellow, black and green tones. It belongs to the silicate-tectosilicate group and its hardness is 7 on the Mohs scale.
