You will definitely fall in love with this necklace and I guarantee you it will become one of your favorite pieces! Wrought in 980 silver, its repousse leaves are dramatically three-dimensional and the patina they acquired over time makes them even more impressive. I believe this is based on a Los Castillo design and it just drives me crazy that I cannot read the signature of its maker - the hallmarks are right under one of the rivets and mostly concealed by it. I can say with certainty though that this is a masterfully executed piece, very carefully finished, with good weight and powerful repousse. It measures a wearable 15 3/4" long (actual length is 16 1/8") by 5/8" wide and weighs 60.3 grams. It is in excellent vintage condition, I believe it dates in the pre-1948 period and all I can read of the hallmarks is "980"!
