Blue Lace Agate is a seam agate, formed in layers usually not more than 1-2 inches thick, in a Dolomite matrix and mined in open trenches.

This agate was hidden for over 50 million years in the quiet isolation of the southwestern African desert and was first uncovered in the early 1960's by an American prospector, George Swanson, in farmland in the Kalahari desert of southern Namibia.

This particular area is believed to be the only known deposit in the world of this specific higher grade semiprecious gemstone material.

It is pale blue, almost lavender, agate with white lace filaments.
