Description

Agates mostly occur as nodules in volcanic rocks or waters containing Silica in solution which is possibly derived from the decomposition of Silicates in the lava. The Siliceous matter is deposited in regular layers resulting in the banded or striped formation. It is very unlikely that you would ever find an exact duplicate of any type of Agate, Brazilian or other.

Carnelian is a red or reddish-brown variant of Chalcedony but also may come in the colors of orange and pink.  It is quite common and usually found in translucent pebble form.  It is found in several areas of Europe, Iceland and Madagascar.
