## Questions & Answers

**Q: Mine came with no instructions. I watched a youtube video but it  is in 1 piece and seems stuck. How do I get it apart?**
A: Mine will not come apart . Very frustrated

**Q: Well this stretche a rig that has Diamonds in t**
A: From my experience it could, but I wouldn't try it.  If you're stretching the ring, you're also stretching the mounts that hold the diamonds.  For me it wouldn't be woth the risk of possibly losing precious diamonds.

**Q: Will this product enlarge a size 11 silver dollar coin ring into a size 12 1/2?**
A: it is safest to enlarge by 1 size

**Q: What is the ring stretcher made of?**
A: All metal construction.  The "stretcher" expands when the plunger is slowly hammered in.  Use a rubber or plastic head hammer, as the metal will mushroom with a regular hammer and will jam.
