Here is one very intricately constructed silver two strand necklace. Consisting of 8mm open circles that interlock at right angles, giving depth and intrigue. The strands measure 17 1/2" and 18 1/2", attached to a bar with spring loaded C clasp. It weighs 52.2 grams and although not hallmarked, it acid tests for sterling silver.
The patina is amazing and has that Mexican silver 'look.' Stunning piece!
