I'll make these rings in sterling silver or niobium wire of different sizes and in different colours and diameters. You can choose between the sizes of 0.8mm, 1mm, 1.2mm or 1.6mm ( 20, 18, 16 or 14 gauge) for the wire, and 8mm, 10mm or 12mm in inner diameter
In the options you can choose if you want the ring to be polished sterling silver, black niobium or gray (natural) niobium and if you want a brass or copper ball. The ball works as a captive bead with 14g (1.6mm) and 16g (1.2mm) rings but hangs on the 18g (1mm) and 20g (0.8mm) rings.
By default I send out 4mm balls with the 14g rings and 3mm balls with the rest but If you'd like a different size just write so in the comments.
If you'd like a ring made with thicker wire or a bigger diameter or ball, I'll be happy to make it for you. Just send me a message and I'll calculate the price and get back to you.
