I’m a big fan of rings, but hate it when they lose their luster with all the scratches from normal wear over time.  Even platinum needs a buff or polish here and there despite it being a fairly dense metal.  If you are looking for an alternative metal to slap on your finger, try a tungsten carbide ring.  Tungsten carbide is the most wear resistant metal and always maintains a permanently polished luster.  Tungsten is about 10 times harder than 18K Gold, 5 times harder than tool steel, and 4 times harder than titanium.  Tungsten rings will hold their shape and shine longer than any ring on the market; they are literally scratch proof.  I have had mine for quite some time and I love it!  Trust me, you will get a lot of compliments!
