...on this great deal!

I bought two One rings to compare.  This tungsten carbide ring, and a stainless steel ring.  You can see in my photos this tungsten ring on the left, stainless on the right.  When on my finger, the tungsten ring is on first.

You can tell the stainless ring is much thinner metal.  The tungsten is also twice as heavy making it feel more authentic while the stainless steel ring feels a bit like costume jewelry.

While both One rings are 6mm wide, the Stainless ring appears wider and lettering appears larger and easier to read. The tungsten ring is much more domed while the stainless is only slightly domed, which I believe is the reason for this optical illusion. In reality I believe both rings have the same size etched letters, and to the naked eye both One rings need good light to be visible; the camera really helps the letters show up.

Stainless steel will scratch while tungsten doesnt scratch.  If you're going to use a necklace chain for your ring, definitely go for the tungsten to keep it nice looking.  If you're just wearing the ring to help immerse into the movie , then either version will do.

I prefer this tungsten version for the authentic feel and durability.  It would be the One ring Id show off to others.
