my second tungsten ring , May 05, 2009
By : Tad (San Ramon, CA USA)
This is my second tungsten ring. The first one was too big, slipped off and I lost it at a club. I decided to go down a half size smaller this time. I ordered the same exact one as last time because the pattern job looks really good...
The Keystone is designed with masculinity in mind. The laser engraved pattern is reminiscent of the ancient Greco-Roman era, when strength and honor defined men. When you combine this with the durability Tungsten Forever is famous for, you get a ring that actually represents you as an individual. A polished groove on each edge frames the etching. We laser etch the ring twice to ensure maximum clarity, contrast, and quality. Unlike other tungsten rings online, our Tungsten Forever™ bands are independently tested to guarantee they are the toughest of them all!
Lifetime Sizing, Lifetime Warranty, & Ships in 1 business day! PLEASE NOTE : Tungsten rings are heavy and Comfort Fit , we recommend ordering a half size smaller if sized with the "rings on a key-chain" or Standard Fit rings. Call us for a free sizing consultation.
