Pattern Description: Six overlapping circles ring the center of these large bowls. Small beaded circles occupy the space where the circles overlap and plumes where the circles don't overlap.
This unique pattern is very easy to identify with the six large overlapping rings that have stippling and large raised dots in the overlapping sections. The outer edge is plain, as is the back of this large bowl. The exterior is uniridized. The bowls can be either round (ICS) or ruffled with 6 or 8 ruffles. They measure across about 9″ to 11 5/8″. Typically found in amethyst; very few are reported in peach opal, typically the most prolific color for Dugan.
