|The hardest substance on earth meets a miracle of science Tungsten and DiamondAura have a natural chemistry, so we forged a ring that celebrates them both. We started with tungsten. Named for the old Swedish word for “;heavy stone,”; tungsten is four times harder than titanium and 71% denser than lead. It’s so tough that when they need to cut it and polish it they have to use diamonds…the hardest substance on Earth. Unlike other fine metals, the spectacular polish and shine will never dull and will maintain its “;just bought”; appearance. You’ll be amazed how well this ring balances a heavyweight feel with “;forget-you’re-wearing-it”; comfort. Strikingly handsome in its natural gunmetal grey color. Next, we inlaid the entire circumference with a full carat of DiamondAura rounds This lab-forged stone not only emulates the world’s most perfect diamonds… it surpasses them. Crafted in a complex process that involves heating rare minerals to temperatures of almost 5000�, DiamondAura delivers unbelievable clarity for a fraction of the price of mined diamonds. Together these two are the perfect symbol of a relationship built to last.
