Size 5 1/4 nielloware flip ring. Mekkalah on one side and the Dancing Angel on the other. It flips with a nice tight snap. Marked silver. The disc is approx 1/2 " wide and 5/8" tall. Shoulders have a decorative engraving on them. This is a nice heavy well made peice in excellent condition. I collected for decades, too many pieces to polish it all, watch for more listings.
