Carbon, as you know, is what makes diamonds so hard. On the hardness scale where diamonds rank at 10.0, tungsten carbide rings sit at 9.5. Compare that to platinum (4.0), white gold (3.0), and even titanium (6.0) and you can see that tungsten carbide easily outranks other metals in hardness. Rings that have a higher hardness last …
