[Rokka] Rokka Ring with Petit Gold "en"

"Honor the earth, and wear the light."

¥97,900 (tax incl.)

Through the endless hexagon runs a small golden “en,” a thread of connection.
The matte-finished metal carries a cool, understated presence.
Inside the band, a lab-grown diamond glints quietly.
A small treasure that only you know about.

Sizes are Japanese ring sizes. If in doubt, we recommend your exact size or half a size up. Ring sizer rental →
