This Margot de Taxco is 16.5in. long and weighs 85.2 grams. The width that it sits up on the neck is 1.25in. making this a quite sizable and bold look. Appropriately hallmarked for Margot de Taxco as shown in photo. I do not like to use the word "rare" to freely but I think this Margot design is truly rare. A breathtaking design just, LOOK AT THAT NECKLACE!
