These rings are made by us! These are really high quality 100% Brass Rings. I have formed the shank, soldered on the Claw Wires with Silver Solder as you can see a bit of White color at the joints, and I have given these a good polish. These are handmade so expect a tad of variation. These are not Cheap ones that are usually available. The metal is Pure Brass, not Brass Plated and expect these to feel more substantial than the cheapie ones. I think this is a very unique product. I have all sizes of these available right now, and if you need more I can always make more of them (with some lead time). We also show what a ring would look like with a stone set in.
