I make these rings from 2mm round recycled sterling silver or copper wire, I put it through my patterned rolling mill to give it a s"snakeskin" like criss cross pattern. Afterwards I make it in to a ring, solder it shut and size it. I oxidize it, then I polish most of the oxide off to bring out the detail in the pattern.
I make the rings in three different sizes:
Small: Inside Diameter: 16.41mm, Inside Circumference: 51.55mm, US and Canada size 5 7/8, British and Australian size L1/2
Medium: Inside Diameter: 17.35mm, Inside Circumference: 54.51mm, US and Canada size 7, British and Australian size O
Large: Inside Diameter: 18.19mm, Inside Circumference: 57.15mm, US and Canada size 8, British and Australian size Q
I have fairly "normal" sized hands and for me the Small fits on the ring finger, the Medium on the middle finger and the Large on the index finger. But if you'd like a bigger or smaller size or a size in between let me know and I'll size it for you.
These rings look really nice stacked together so I made some sets of three where you get a bit of a discount.
