This is a beautiful pendant top featuring Mikimoto pearls and elegant engraving. You can use it as a necklace by pairing it with your own chain. Material: K14 Yellow Gold Size: Approximately 4.3-8.2mm overall The larger pearl is about 7mm. (I don't have calipers, so the measurement isn't exact.) I believe it is in good condition, but please note that it has been stored and inspected by a private individual, so there may be oversights. Thank you for your understanding. It will be shipped in simple packaging. Thank you.
