Mexican silver chain necklaces bearing the signature of Pedro Castillo are not easy to come upon and in all my years of dealing in Taxco jewelry, I have never seen this specific design before. I don't even know how to describe the architectural links that make it up - they look to me like hourglasses wrought in sterling with their tops and bottoms removed, held together with sturdy oval connectors made of thick silver wire. This is one of those necklaces that one never tires of, its construction quite impressive, its geometry intense, its weight a welcome, intimate "burden" around the neck. Made by Pedro for Tono some time around the middle of the 20th c., it is a dedicated collector's dream-come-true measuring 28 1/2" long by 5/16" wide. The necklace weighs 63.6 grams
and is signed with maker's conjoined initials "PC" as shown as well as "HECHO EN MEXICO TAXCO", "925" and Eagle 3 assay mark; the Tono signature is on the tongue of the clasp. It dates in the 1950s-60s
and is in excellent vintage condition with fantastic architecturality, the patina you want to see on a well-loved, well-cared for piece of jewelry from the middle of the 20th c., great weight and craftsmanship and no damage or repairs noted.
