It is polished to a perfect mirror finish using diamonds, and unlike other metals, it will retain the exact polish for decades to come. In fact, the only way to scratch a tungsten bracelet or ring is with a diamond. No other material will affect it. Tungsten is about 10 Times harder than 18K Gold, 5 Times harder than tool steel, and 4 Times harder than titanium. Reflection with a sparkling luster. Mirror polished finish and corrosion resistance. *Please note: Our Tungsten bands tend to run about a half size larger than normal. For a better fit, we recommend that you order a half size under your regular size. RingFormType : band SettingType : Band Style : Modern UnspscCode : 54100000
