AG205 Prairie Agate

AG205 Prairie Agate


AG205  Here is a very nice Prairie Agate from the Cheyenne River area in South Dakota.  This interesting Prairie Agate measures almost 4″ x 3 1/4″ x almost 3 1/4″ with a nice polish on the cut face with the balance left natural.  This interesting Prairie Agate was cut and polished in our own Lapidary department to show the unique design and banding configuration inside.

In stock


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, Fairburn or other.
