The green stones are decorated with sparkly prong set crear stones. 11.5” drop length. 18” around the neck. Can be shortened to any desired length due to its closure type. Some minor wear of gold plating on the chain, but not too noticeable and mostly on the sides and back. The rest of it is in excellent condition, as pictured.
