Chalcedony can be separated into the translucent category known as agate and the opaque category jasper. Within agate and jasper there are numerous varieties that can be separated by color, appearance, and phenomenon. Some of the best-known chalcedonies are lace agate, bloodstone, carnelian, chrysoprase, and onyx.
