This is a dramatic looking necklace. The links are beautifully crafted in a superb design and each one has a natural stone center. I believe the green stones are onyx but am not sure what the others are. This necklace is gorgeous on. The chain is exceptionally nice. It weighs about 42 grams and the silver is 950 so it is more than our standard of 925. Necklace was made in Peru and is in excellent condition. There is a safety catch on the clasp.
