found this ring sunday morning at a park. steady 14 vdi reading. its a toe ring. my ? is , can the ring be silver even if the vdi is not in the high 70 s or 80 s. i know gold will register in the low vdi s because i found a small ring ,a while ago, stamped 10 k that was a solid 8 vdi. this one has no stamp .it had a little tarnish on it so thats why im leaning to silver and not gold.
