11.8" Multi-Colored, Orbicular Ocean Jasper Slab - Madagascar

This is a gorgeous, 11.8" wide polished slab of high quality ocean jasper from the original ocean jasper mine in Madagascar. These ocean jasper specimens have a very unique character, as the patterns and colors are so different between them. It has been cut flat and polished to a glossy-finish on both sides, making for a breathtaking display.

This slab is accompanied by a display stand.

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.
