This is a stylish Modernist Pendant made of a detailed Mobius Strip and a Pearl Center suspended on a double link with snake chain. It is hallmarked 14 K on the back of the bale and the lozenge next to the clasp. It is 1 3/8" by 3/8" and is in excellent estate condition.
A Mobius strip is a geometric shape with just one side and edge. What a clever design for this lovely pendant.
