It may also be Utilized in coating sterling silver to guard against tarnish (silver sulfide, Ag2S, developed from atmospheric hydrogen sulfide, H2S).

It is better to take care of the jewelry properly so you will not need to have to spend a lot cash replating it greater than you should.
"Its rarity and the large world-wide demand from customers as a result of use in auto manufacturing can make the rhodium price go up significantly," says Peterson.
