This 6 mm band has a two-tone look to it because the step-edge of the ring is high polished while the center has a brushed matte finish providing a more subdued Titanium grey color. The ring is made entirely out of air craft grade titanium and is hypoallergenic. It about as durable as platinum, but much more affordable. The inside of the band is comfort fit so that it can comfortably rest on the finger and can also be personalized with an engraving up to 15 characters.
