PR1009 South Dakota Prairie Agate


This is a nice, above average quality South Dakota Prairie Agate.   It measures 4 1/4″ x 3 1/8″ x  2 5/8″ and was polished on all sides here at the Rock Shed.  This cool Agate has lots of Prairie Agate banding with a pretty Yellowish Cream, Grey, Brown accent colors.  A nice display piece for your collection.  Very nice!

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.
