An amazing golden pattern embellishes the surface of this slightly rounded, wonderfully smooth, black, lustrous ring. The step-down edge is skillfully rounded and smoothed. A wonderful example of the fine craftsmanship.

 Tungsten is one of the hardest metals on the planet. It’s durability is absolutely unmatched in the jewelry industry. Tungsten is 10 times harder than 18K gold, 5 times harder than tool steel and 4 times harder than titanium. It measures between an 8 and 9 on the Mohs scale, with diamonds being the highest at a 10. Tungsten has been used for decades in industrial applications where only the strongest and hardest metal will suffice. The incredible strength and timeless beauty of our tungsten rings will have you cherishing them for a lifetime.  All of our rings are manufactured with tungsten carbide using nickel as a binding agent. Many companies choose to use cobalt as a binder because it is slightly cheaper. While either element will work just fine, cobalt has a higher tendency to have adverse reactions with some people’s skin. This is why we use nickel. Although in some extremely rare cases a customer will discover he or she has an allergy to nickel, our rings are generally considered to be hypo-allergenic.

We’ve included a helpful PDF guide to assist you in finding the right size. If you print out the PDF ring sizing guide, be sure to print it at 100% size for accuracy purposes. If you print it at anything other than 100% it will not be accurate. Of course the best way to get sized would be to visit a local jeweler. However you decide to determine your size, keep in mind that all of our rings are “comfort fit”. Generally when sizing for a comfort fit ring you will want to select a half size smaller than normal. So, if you determine that you are a size 10, you may want to select a size 9.5. If you do choose the wrong size, it’s no problem. Just contact us and we’ll be happy to do an exchange.
