Green recycled wine bottle glass set in pure silver atop a sterling silver band. I LOVE the way this ring turned out – the glass positively glows – it’s just so cool. It’s big, it’s a statement, it’s durable, it’s one of kind – and, if you are a wine person, this ring is for you. I have given the inside the of bezel a high polish so the light comes in through the glass and bounces back to give that wonderful glow – even if aren’t a wine person – it could absolutely be a super power ring, or just a modern green ring. In any case, it’s pretty wonderful.
