Very Rare Green Eys Sterling Silver Skull Ring. Size 7.5 or 8. Unknown Stone, Maybe it’s jade or Turquoise. Old Hallmark “Mexico 925″. I had never seen this ring before, it might be one of a king. Message me if you have any question. Expect some delay depends on custum process. Mexican Post is slow. Sometimes it takes 1-2 month to USA. Russia because of tracking issues. 2 – 7 days.
