This is a ball chain and pendant top. It's a hand-carved silver necklace by a Hawaiian jewelry designer. The color is yellow gold, and it has a spoon-shaped top with a peridot embedded in it. Chain length: 40cm I purchased it from a Hawaiian jewelry specialty store from the designer. I believe the original price was around 50,000 yen when I bought it several years ago. I wore it once in Hawaii, and then I wiped it and left it, so I'm putting it up for sale. The hallmarks are SILVER and SILVER925.
