Stephen Dweck Mother of Pearl, MOP, Pendant/Bangle

I have only one very nice piece, with a cut signature of “Stephen Dweck CR” in a circle on the back, near bottom of the piece. It is a seven-sided mother of pearl necklace pendant or dangle earring without clip or hook and in as near new condition as is possible. This item will also be on display at Lincoln Antique Mall, Lincoln Mo. So please check with me regarding availability if interested.
