New, Unused Larimar 6-7mm Inner diameter approximately 15cm Some matrix is present. Many beads have a turtle pattern, please check the photos. I love Larimar and bought too much, so I'm selling this one without using it. I purchased it from a popular stone shop. It's a genuine item, guaranteed. It was a great deal at 3900 yen. It's actually brighter and more lustrous than in the photos, and very beautiful.
