Buy real 100%. Not the other crap.
Most of the tunstang rings for sale are platted white gold, gold, rose gold, black or what ever crazy color you find. In fact, I can't find one for Sale on ebay or Amazon not platted.
Plating will come off.
This ring is 100% tungstan. Used with no scratches. Real tungstan doesn't scratch. Thats why it's the best material.
