AG317 Laguna Agate

++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. Laguna Agate is on of the most highly praised banded agates in the world. It is known for its extremely tight banding and vibrant shades of red and scarlet. Laguna Agate is a variety of banded Chalcedony, a mineral of the Quartz family. Though predominantly scarlet, its layers may contain shades of deep red, milky white, yellow, gold and brown.
