The ring

Specs: Tungsten Carbide (an alloy with nickel binder)
Size: 11.5

Several cool notes about Tungsten and reasons why I picked this metal:

1. Tungsten Rings are the most wear-resistant rings available on the planet.
   
2. Tungsten is about 10 times harder than 18K Gold, 5 times harder than tool steel, and 4 times harder than titanium. Tungsten measures between 8 and 9 on the Mohs hardness scale. (Diamonds are a 10 - the highest.)
   
3. Due to their extreme hardness, Tungsten Rings will hold their shape and shine longer than any ring on the market.
   
4. Tungsten rings have been referred to as "Permanently Polished Rings."

I bought it from these guys, http://www.tungstenworld.com/, but drove into their local HQ to pick it up and try on for size.

Price is about 1/3 of stand alone jeweler such as Robins Bros.
