Elegant Silver 2 mm Rope Chain Necklace

This elegant silver necklace showcases a minimalist rope chain design that gracefully adorns the collarbone. Its subtle shimmer and refined linked elements make it a versatile accessory for any occasion. I purchased this second-hand at a silver shop. I was told it was sterling, but I can't make out the marking. Note: There is oxidization on the clasp pieces. TL5
