This is an old design #366 linear hallmark for Los Castillo and is definitely a Margot design when she was married to Antonio. The drop is 4.25in. across and 3in. deep. The chain swirls are half an inch wide. The weight is 81 grams heavy. This design makes a statement when worn but also is a tasteful compliment that you can wear anywhere. I love this piece, just LOOK AT THAT NECKLACE!
