This was purchased by my grandmother. It looks like it's hardly been used. It's 18cm in diameter (photo 2). The string is tied tightly, so it's probably not a necklace (photo 5). This accessory features red and yellow wave-patterned beads. - Type: Necklace - Material: Beads, string - Colors: Red, yellow, black - Bead design: Wave pattern - Length: Approximately 40cm Thank you for looking.
