French Edwardian PEARL Antique 18k Gold Ring Solitaire Cupped Linear Ring

Elegant little antique natural pearl solitaire in a cupped setting. French Edwardian era piece. Would be the perfect stacking ring or pinky ring. No hallmarks remain but sold as 18k which is the standard in France and tested to confirm. Ring is currently about a size 4 1/2. The pearl is about 5 mm in diameter. The setting stands 6mm off the finger.
