Gorgeous handmade teal Icelandic seaglass spinner ring. I have bezel set this pretty piece of seaglass in sterling silver on a polished sterling silver band that spins freely on a 10mm wide hammered sterling silver main band. This ring measures a size P 1/5 US 7 3/4 but because of the width of the band will fit like a size O 1/2  US 7 1/4
I cannot alter the size of spinner rings.
