POLISHED BERBER AGATE

Berber agate, also known by some as Antelope Agate, is the trade name for an agate collected near Sidi Rahal, Morocco. They occur within Triassic basaltoids and have characteristic coloration and internal structures that make them easily identifiable to collectors. They typically feature a pink outer rim composed of opaque opal-CT, with red to red-brown interior layers that gain their color from iron impurities (goethite and hematite). The centers of these nodules are often blue-gray/white-gray and contain small amounts of moganite.
