Ocean jasper is a rare type of silicified rhyolite (considered both an agate and a jasper), mined in a single location on the Ambolobozo Peninsula of Madagascar. The deposits are found on the coastline (hence the name) and can only be reached by boat and mined during low tide. The deposit formed as a rhyolite flow but has been completely silicified. The rhyolitic eyes or orbs come in an astonishing array of colors and color combinations. The background can be white, pink, green, red, or yellow. Botryoidal formations as well as white and deep green druzy are also common.
