What is rhodium plated gold?
Correspondingly, how long will rhodium plating last?
In fact, Rhodium plating only lasts between 3 months and a year, depending on the amount of wear that can be seen. You will know when your rings need to be re-plated again, because you will start to see glimmers of yellow gold showing through the coating of the Rhodium plating.
Also question is, is rhodium better than gold?
Rhodium is much harder than gold and thus, as a plating, will last longer and be more scratch resistant than a gold plating. If you are plating over silver, a rhodium plating requires a pre-plating of nickel. Gold can be plated over silver with or without a nickel pre-plate.
They are two different things. Sterling silver is 92.5% silver with 7.5% copper added. Rhodium plated silver is fine or sterling silver that is polished and dipped in rhodium. It has a bright finish, similar to white gold items, and it doesn't tarnish.
