10.6" Intriguing, Free-Standing, Polished Ocean Jasper/Agate (15 lbs.)
This is an exceptionally interesting, 10.6" tall polished piece of ocean jasper and agate from the Ambolobozo Peninsula of Madagascar. The agate bears a wide variety of colors, including hues of green, yellow, black, and orange, with interlaced patches and seams of quartz throughout one face and an edge of the specimen. The reverse face is a smooth creamy white jasper with a banded border. The base of the stone has been cut flat so that it stands unassisted on an even surface. It is quite astonishing and makes for a unique display piece. This specimen weighs just over 15 pounds!
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.
