**6mm Red Blue Brushed Black Tungsten Ring** This tri-tone tungsten carbide ring is made from the hardest metal, polished to a perfect mirror finish using diamonds, ensuring it retains its shine for decades. Only a diamond can scratch its surface, making it incredibly durable. Tungsten is 10 times harder than 18K gold, 5 times harder than tool steel, and 4 times harder than titanium. The ring features a 6mm width, dome shape, brushed black finish with a striking red groove inlay, and blue IP plating. It also has an offset groove for a unique design. Made from hypoallergenic, jewelry-grade tungsten carbide, the ring contains no cobalt and offers a comfort fit. Available in sizes 6-12, including half sizes, and comes with a complimentary ring box.
