Quality obsidian drops necklace with hand made chain is a great gift for the holidays. The length is 21 1/2in. You can hook it into the chain anywhere for shorter looks. Great to adjust to the neckline. The weight is approximately 52 grams heavy with the bars on the chain solid silver. The beads are thick silver as well. The drop is 4.5 inches across and the obsidian drops are safely in their cages with each one being 1.25in. tall. The hallmark is on a hanging tag. This is talked about in the Mexican Silver books but it is really hard to actually see one somewhere. They were taken off or just lost. This one is intact and hallmarked as shown with an early eagle of either a 1 or a 7? No damage anywhere and this appears to have been sitting in a drawer for it's whole lifetime. A wonderful example, just LOOK AT THAT NECKLACE!
