Tunu is a pyramid brass statement ring; a bold geometric pyramid form sits on the finger as a sculptural focal piece. Also described as a pyramid ring or geometric statement ring for women. An ancient sand casting process means the shape is formed in a sand mold before liquid brass fills it, no two pieces come out of the mold exactly alike. A nano ceramic e-coat over solid recycled brass delivers superior durability and resistance to water, sweat, and tarnishing. Wear it every day. The coating handles the rest. Product Details Material: Solid recycled brass with nano ceramic e-coat Tarnish-resistant, water-resistant, hypoallergenic, nickel free Ethically handcrafted by Fair Trade artisans Tunu means treasure or wonder or precious gift in Swahili, the thing that makes you stop.
