This is a fantastic vintage sakura or cherry blossom branch textured Japanese akoya saltwater cultured pearl ring.

The pearl is 6.50mm round. It has great luster with rosy overtones.

It is set in solid sterling silver. It is stamped "STER". It is highly detailed with branch texture surrounding a delicately detailed blossom in the center. US size 7 3/4. Sizing may be difficult as the texturing goes all the way around the shank. 

All pearls are truly vintage and have only been lightly cleaned.
