It is exciting to find this Arte en Plata necklace which is monumental in stature and rarity. The Jacopo brothers operated Arte en Plata Taller for a short while and featured many talented artists. This piece is an early numbered design 23 and signed AMC as well as the Arte en Plata. The pectoral is thick silver and weighs 96 grams heavy. The wearable length is approximately 17 inches. The drop of flowing leaves is a 4in. x 4in. triangular shape. The patina is beautiful with the higher than sterling purity. The quality of this piece is unsurpassed and the design is gorgeous, just LOOK AT THAT NECKLACE!
