Ring resizing?
I have a ring that I made in a size 7.25 for sale; a buyer who is a
size 9 wants it. The most I have ever stretched a ring is up to 1 full size, with a roller stretcher. The stone, which is already set, is very unique, so this would be my preferred option, but I am afraid that stretching it almost 2 sizes might be too much for the sterling silver. Does anyone have any advice on stretching? Am I going to have to pop the stone out and sleeve some more silver into the band? thanks, -stacy |

Ring resizing?
Hi Stacy
It's hard to answer your question without more details or a pic of the ring.... How thick is the band of the ring? Sterling will stretch that far, so long as you have the thickness there and the metal is still in an annealed state. So it will depend on how much working of the metal you did after the last solder join... Also, what type of setting is the stone in? Can you describe the ring or post a pic? And what is the stone? I'd say most likely it will be fine to resize with a roller stretcher (DON'T attempt it with an upright wedding ring stretcher), but more info would help us know for sure.... Tracy |

Ring resizing?
If you do decide to resize by cutting and putting a piece in, one
finger size is equal to 1.1mm As other posters have pointed out though, silver is a great conductor of heat and unless your shank is very narrow, this could be risky even with a protective paste or such. Removing the stone could also damage the ring (or stone) depending on what the stone is and how it is set..... we really need to know what we're advising you on. |

But in U.S. sizes, one full size is 2.5 millimeters. If one is being very precise, I think it's actually 2.54 mm... And then, since you cut the shank open to insert the piece, you can add another .25 mm to make up for the width of the saw cut. Again, for real precision, remember that this length of stock is most accurately measured on the inside of the ring, at the finger or mandrel surface. But actually measuring it on the inside is a pain in the backside. Most people mark the ring, and the stock, on the outside surface. For fractions of a size, or a size or even two, the result is the stock is very slightly shorter, so the ring ends up a little bit tighter than the desired size. That's perfect, since it allows you to clean up the solder and the addition, and mallet the ring properly round again, and the slight stretching that causes then gives you the desired end size. But if you're making a ring more than maybe a size and a half, or two sizes, larger, you start to need to measure longer than that theoretical 2.5 mm per size, or the ring will end up significantly too small. Practice will teach you how much to adjust. The other way to do this which avoids the math is simply to cut the shank, slide it up a ring mandrel to the desired size, making sure the shank stays flush to the madrel while doing this. Then use a divider to measure the resulting gap and mark your sizing stock to cut the needed insert piece. Peter |

Peter From looking at the picture you've posted, the bezel surounding the agate is not holding the stone in place. I can see gaps on the outer edges which means you could probably soak the ring in a product called " Atack " and that will release the stone without hurting the agate at all. Agates are around 71/2 on the hardness scale so you wont hurt the the polish in any way. This would be the easiest way to approach this job as anyone not familiar with soldering the ring in wet sand or water most often overheats the shank and makes more problems then they'd like. Mark |

Though I doubt you'll see a flood of people taking you up on the offer. Still, another good option for anyone who finds your offer, decodes your email address, but doesn't find any of the other existing free sites out there that host pictures for people. Thanks. Peter |

This is a picture of the ring: http://www.flickr.com/photos/schristopher/3066126151/ The band is about 1mm thick, the stone is a moss agate, and it is bezel-set. I've had a couple of people comment that stretching it will probably be fine, so I will probably try that first. I really appreciate everyone's help! thanks, -stacy Also, what type of setting is the stone in? Can you describe the ring or post a pic? And what is the stone? |
