Reducing my jewelry collection This has some light use, but still a piece that will last you a lifetime! Made in 14k solid gold, the alloy gives our pieces its beautiful, subtle hue. Band height: 3 mm. Band thickness: 1 mm. You can’t go wrong with this basic piece. Handcrafted in 14k solid gold, you can wear it all day without taking it off. Pairs well with our other Stacker rings for the perfect contrast.
