This is a lovely Arts & Crafts 10k yellow gold lavalier and chain, c. 1900. The lavalier is set with a single old European cut diamond (about 5 points) and a natural freshwater pearl drop. The lavalier measures 2" x 1/2" and the chain is 16 1/2" long. The chain is marked 10k and the lavalier tests 10k gold. Condition is excellent.
