Tungsten Carbide is an exceptionally hard and durable metal, polished with diamond tools to achieve a brilliant, mirror-like finish that lasts over time. While highly resistant to scratches, harder materials, such as diamonds, may scratch tungsten. Tungsten is significantly harder than metals like 18K gold, tool steel, and titanium, making it an excellent choice for long-lasting jewelry. It offers a reflective surface with a sparkling luster, a mirror-polished finish, and excellent corrosion resistance. All our rings are engraved with "Tungsten Carbide" to ensure authenticity. Additionally, all rings feature a Comfort Fit and are made without cobalt, making them hypoallergenic.
