Solid Tungsten construction with precision laser etched letters and nice brush-finish in the center or a Black tungsten ring with laser etched fraternity crest and Greek letters designed exclusively by The Collegiate Standard. Whichever you pick its sure to be a hit.
Tungsten is a super hard and durable metal, with a melting point of more than 6,000 degrees F. The ring will not tarnish or corrode, and is virtually scratch-proof - it will look exactly the same decades later.
