This necklace is stunning ....wow! The colors in the abalone/ paua are gorgeous and seem ever changing depending on how the lights hit it! The abalone itself measures aprox. 2 inches long x 1 1/8 inch across at its widest point, the entire pendant measures aprox. 2 3/4 inches long ( refer to last photo with nickle ) the pendant starts off with a very detailed antique silver tone nickle free clam charm dangling from that is the abalone and resting on top is an adorable silver tone sea turtle seeming to be "swimming in the ocean of abalone " This special piece comes on it's own silver tone chain with a lobster claw clasp. The chain is 18 inches in length.
