K18 and Pearl TASAKI Charm Size: Approximately 7mm (pearl is about 6mm) With certificate. The storage bag shown below is not included. The loop is small, so it won't fit on a regular necklace chain. I used it by threading it onto a necklace with a slide ball adjuster. There are some minor scratches and signs of use. - Brand: TASAKI - Material: K18 (18 karat gold) Thank you for viewing.
