Check out this cute little vintage-looking ring! It’s lightweight, adjustable, and nickel free, with an antique brass filigree base. The base is just over a half inch wide. The floral piece (made of resin) is the prettiest pale cornflower blue (kind of a bright blue/gray).
This ring is water proof, but I wouldn’t recommend submerging it in water for long periods of time (like while washing dishes).
