For your consideration is this beautiful pastel guilloche bar pin. It is signed Champleve Sterling with the Charles M Robbins makers hallmarks on back. The piece is nicely hand painted with a lovely pink and green design on fine white enamel and clear finish. The Charles Robbins hallmark dates this piece to between 1892-1912. It has a safety pin like clasp.
The pin measures just shy of 2 and 1/2 inch by 3/8 inches at center.
It is in excellent functioning condition with no damage to the enamel. The back has an uneven patina which I can clean if requested by purchaser. Please ignore glare on enamel... so much prettier in person!
