Jasper: The jasper refers to green, dark green or dark green nephrite, which is commonly green for spinach. High quality jasper is also a good variety. However, Jasper usually does not have a very uniform texture and often contains obvious dark spots and white stiffness. Most of the black spots are caused by black magnetic minerals.
