Solid Tungsten construction with a nice brush-finish in the center. Precision laser etched Alpha Tau Omega letters. 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. All of our jewelry comes with a life-time warranty. The perfect gift for that special big or little or even yourself! Comes in a nice ring box!
