Polka dot agate chunks

These are large, random, orange agate chunks. They have been treated with acid so that some of the surfaces are frosted and some are clear. The clear spaces are in the shape of polka dots. The chunks range from 16 mm to 20 mm long and average 14 mm wide. The strands have a nice variation of color from light to dark. Each strand is 16 inches long and contains approximately 21 beads.
