Titanium belly rings are lightweight (around 60% the weight of stainless
steel given the same volume), highly corrosion resistant, and less likely
to react with body fluids. Non-magnetic, it can be anodized to create
a layer of colored oxide on the surface. Common colors are yellow, blue, purple,
green, and rainbow. Titanium is also revered for its safety- it can be sterilized in an autoclave.
