Bijumam's Rolling Ring This popular design features a crown and delicate openwork, making it very cute. I tried it on my index finger for the first time in a while, and it was too loose. I've lost a rolling ring from my index finger before, so I've treasured this one, but I've decided to let it go. I usually wear a size 13 ring. Please refer to the image of it on a thin marker for the size reference.
