Description

Zyamara Mad River Agate is a type of agate that is found in Madagascar. It is a banded form of microcrystalline quartz that displays translucence and, in some cases, banding. It can also contain sagenite crystals, which are needle-like formations of rutile. Mad River Agate is known for its amazing color patterns and unique beauty.

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.
