Jasper Heart, Indonesia

Jasper is a term that can be applied to an opaque variety of chalcedony. The opaqueness is due to a higher concentration of impurities mixed with silica/quartz compared to other varieties of silica, such as quartz or agates. Like agate it may form in a wide variety of colors, and is often multi-colored. Brecciated jasper is known for its dramatic, fractured patterns that look like natural mosaic artwork. "Breccia" or "brecciated" is the term for rock that has been shattered by geologic forces and later cemented back together by means of percolation and solidification of mineral-rich solutions. Each heart is unique- the carving you receive may differ in size, shape, coloring, and pattern than the one seen in the picture.
