The Signature - Black Tungsten Ring with Iridescent Groove

This tungsten, cobalt-free ring is designed with an iridescent groove to add a funky pop of color. Tungsten metal rings are the most wear-resistant rings on earth - 10x harder than gold, 5x harder than tool steel, 4x harder than titanium. Each ring is beautifully presented in a custom leather ring box. Material: Tungsten Width: 8mmStyle: Comfort fit Please note: Natural tungsten is a silver/gray color. Black plating has been added through a series of plating processes. Plating is very strong on tungsten rings but we strongly recommend protecting your ring from rough environments (maybe avoid rock climbing in it).
