A polished Polyhedroid Agate specimen set of three, resulting from multiple chambers that were not completely fused together across the entire piece. The images show how they fit together. They show crystal on the outer edges, filled with agate sections in brown, yellow, and white, or in shades of blue. Both agate sections show tiny vugs, revealing botryoidal agate formation or sparkling druzy. The areas with blue agate are UV reactive.

Polyhedroid Agates were found in Paraiba, Brazil, but are now unavailable. They are a unique formation of agate, featuring naturally flat surfaces at a variety of different angles. They are believed to have formed in the negative spaces between large crystal blades of calcite or aragonite, and can occasionally feature multiple "chambers" where those blades eroded and adjacent agates fused together.
