This necklace has a heart-shaped crystal pendant in a sterling frame, on a very fine (narrow) Venetian box chain. The pendant, including the bail, measures 3/4 x 7/16 inches, and the sterling chain is 24-inches long. The pendant is marked "925" and the chain "Italy 925" plus a designers mark of an "A" with a half-circle mark above it. The necklace has some age-related patina, and I will polish it lightly before shipping unless requested otherwise. A perfect necklace for a sweetheart! It will be shipped in a gift box.
