Here's a rare polyhedroid agate from Brazil. This extinct material was mined in the '70s and is said to have achieved its bizarre angular form by depositing in the spaces between large carbonate crystals. The crystals weathered away, but the agates remained - and what special agates they are.This excellent specimen features blue/gray and black banding with a botryoidal agate center. Large poly's don't come up that often - especially with proven agate centers and such nice form. A very special addition to any collection. This piece will cut many large collector slabs, or polish the face as is and preserve for posterity. No visible fractures. Flouresces green under SWUV light. weighs 3lb, 2oz.approx. 6" x 2" x 4.75"Pictured dry with ruler and wet.Stones are lapidary rough, not polished.Win mutiple items and combine to save on shipping.USA only.!
