 If your ring is made from softer metals such as gold or silver, it will scratch more easily and wear faster. There are more practical metals, such as platinum, but also more expensive.

 The answer to your question depends on how often you will wear a piece of jewelry, because the longer and more you use, say, mens diamond eternity wedding bands, the more it will wear out. To be blunt and factual, gold jewelry (as you probably know) is quite easily damaged and deformed because of its metal features. But let's say jewelry made of silver is very difficult to damage badly. So the choice is yours, good luck!
