23 Inch Sterling Silver heavy curb link chain with a large pendant marked on the back 925 Mexico. The chain is lovely and heavy and is 1/4 inch wide, and the pendant is also large 2 inches long and 1 5/8 inches across. The center of the pendant is amber, and though there are flecks in it, I have not had it tested for real amber. The whole necklace is wonderful. The marks on the back of the pendant are T-14 and what looks like a smudged Mexico, but it could be a makers mark, and also 925. The chain is also marked on the clasp.
