Tungsten carbide makes for a dense and
solid feeling ring. This ring is polished to absolute
mirror finish and will not scratch in everyday use. Being
a 9 on the Mohs hardness scale, only things diamond and sapphire
could scratch, and even then, it wouldn't be deep. Because
these are made by a special process using dedicated equipment,
special requests other than those offered cannot me made. If your size falls between sizes, go with a smaller size. Unworn rings can be traded out for sizing if necessary.
