This incredible vintage necklace is signed Carlos Sterling. It came from an estate which had only the finest jewelry. This necklace is exceptional quality and workmanship. It is a collar style with a large centerpiece. The turquoise is well matched in size and color. There are two hinged pieces along each side. The centerpiece is a beautifully shaped teardrop. Necklace measures about 21" long. The centerpiece is 2 1/8" x 1 1/2" wide. It weighs about 48 grams. Necklace has old patina and is in excellent condition. It is marked Carlos Sterling. This is the only piece I have left from that estate and I am at last ready to part with it. This fine piece of jewelry will give you many years of wearing pleasure.
