This is a necklace. The pendant has a design with a black stone. Pendant size (including fittings): 2cm long, 1.5cm wide Chain length (including fittings): 20.5cm Stamped "925" on the back Please allow for slight variations due to amateur measurements. In my opinion, the black design makes it easy to match and a striking color. It would also be stylish to wear it to the sea, river, or casually. If you like it, please consider purchasing it.
