This is a handmade 14k yellow gold Akoya pearl pendant top. The chain is not included. Both the fittings that pierce the pearl and the bail are made of solid 14k gold, not plated or gold-filled. The hallmark indicates the gold purity, with "585" stamped on it. The pearl is an Akoya pearl from Ago Bay, Mie Prefecture, and has a mysterious color like oil. The shape is baroque. It's a large pearl, 8mm or more, and I think it's a very unique pearl.
