Kambaba Jasper Heart

Kambaba jasper is an orbicular jasper from Madagascar featuring swirls and orbs of light to dark green and black. Mineralogically, it is classified as a highly silicified rhyolite or volcanic tuff. An opaque variety of cryptocrystalline quartz (chalcedony), jasper is found worldwide. It owes its opacity and color to its incorporation of varying amounts of other minerals. Red to brown jasper is colored by hematite, yellow to clay, and goethite can make it brown or yellow. There are many varieties of jasper including picture, brecciated, and leopard skin. Oregon is famous for its wide varieties of picture jasper. Other deposits are found in the USA, Mexico, and Africa. Metaphysically, jasper imparts determination and courage.
