Like Jasper, also known as Liverstone, it's not worth much. Just for reference.

Jasper is a silica cryptocrystalline variety. Jasper refers to chalcedony with mineral impurities such as clay minerals and iron oxides in its composition, also known as liverstone, which often contains more than 15% impurities. Due to its impure texture, it is usually opaque or slightly transparent, and its luster is slightly darker than that of ordinary chalcedony. Jasper has a wide range of colors, including red jasper, green jasper, white jasper and yellow jasper. In addition to monochromatic varieties, but also common varieties of mixed colors.
