Ida is a geometric band brass ring, a clean stacking band with a subtle geometric profile that gives it character without adding bulk. Also described as a minimalist stacking ring or geometric band ring for men and women, available in sizes 7 through 10. Cast in sand from molten brass, an ancient method that leaves every piece with its own small imperfections and character. A nano ceramic e-coat over solid recycled brass delivers superior durability and resistance to water, sweat, and tarnishing. Protection that's felt in the wear, not seen on the surface.
