Jaspe Serpentine is a microcrystalline variety of quartz (chalcedony), containing inclusions of other materials, such as hematites and goethite, which give it opacity and color. It is formed from water depositions that have high levels of silica in low temperatures. These waters seeps through rocks and this is how other materials are incorporated during the process. There is a wide variety of colors and drawings in jaspers, although they are usually found in shades of red, yellow, black and green. It belongs to the group of silicates-tectosilicicals and its hardness is 7 on the Mohs scale.
