My jump rings are made completely by me - hand coiled wire on hardened steel mandrels, then precision cut for perfectly flush cut rings. Tumbled with stainless steel shot to clean, harden and bring them to a beautiful shine makes them perfect for making chainmaille or to use however you like in your own handmade jewelry.

Inner diameter is the diameter of the mandrel, or steel rod that I coil the wire onto before cutting into rings. Some springback will occur, making the inner diameter of the ring slightly larger than the mandrel diameter. Inner and outer diameter may be +/- .2mm from these calculations.
*The "actual" measurements on the large diameter sizes above were made after closing the ring with my pliers, tight and flush without any gaps. The bigger the diameter of the ring, the more the coil of wire can "spring back" from the mandrel which it's coiled on, causing the ring, and thus the ID and OD to be larger than the mandrel size. Please note that I still label the rings by the size of the mandrel they were coiled on (or it would be too confusing!)
Please note that ring counts are approximate. I provide them here to help you get an idea of how many rings you are ordering, but do allow for some variance. While the number of rings you receive may vary from the above chart, you will ALWAYS receive the WEIGHT you ordered.

the only jump rings I have ever purchased are from Raine Studio Supplies. They are always perfectly cut and easy to open and close.

As always, these rings are smooth, shiny, and perfectly shaped and got to me in a timely manner.

Amy produces consistent jump rings, which are perfect for my "Jewelry Soldering for Beginners" students. We use them as our training wheels before moving into stacking rings.
Amy’s ends are perfectly flush which allows everyone to fit the ends together and solder with confidence. Great product!

Have ordered multiple times and always great!

I purchase jump rings exclusively from Raine Studios. I don't know what Amy does to them to keep them shining so brightly without any maintenance on my part. Not having to clean a piece every time I wear it keeps me coming back. Great product, Amy! Thanks.

Always the best rings, service, and prices around

Awesome rings! No burrs, perfectly shaped, just the right hardness. I love working with Amy's rings. And the best prices for the best products.

Always 5 stars! I've ordered jump rings from all over, and the quality of these is the best you will find: always shiny, always clean cut, always great service. Love them:)

Rings are uniform, not "over-springy", clean, clean cut. Better than the other two sources I've tried for sterling silver rings.
A bit softer than I'm used to, so need to be extra careful with pliers, but finished jewellery seems to hold up well.
