PRS21 South Dakota Prairie Agate

PRS21 South Dakota Prairie Agate


This is a very beautiful  Polished Prairie Agate Stone from South Dakota.  It measures 4 1/4  x almost 2 5/8″ x  1 3/4″ thick and has a nice polish on the front face.  It is a great size for a small paper weight or just pretty to look at and it would make a great gift. This is a nice quality Prairie Agate.  These agates get their name from where many have been found, out on the prairies of South Dakota.  This agate has been polished  right here in our very own Lapidary Department and shows nice Agate banding and design in the various shades of dark Yellow, Brown, hints of Pink and Grey. A very unique gift.

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.
