The rainbow, blue, and gunmetal black versions of this bracelet engrave white / silver. The rainbow bracelet's colors shift depending on the light and angle you're viewing the bracelet. The engraving color also shifts between silver / white / gray / black as well. The silver, gold and rose gold versions engrave black. The bracelet measures 6” x 1/4” (6x152mm) and is adjustable to fit most wrists, however, since it’s made of steel, it is much harder to bend than my aluminum cuffs.
