To Care For Silver Jewelry
♫ Wednesday, March 23rd, 2011With gold and platinum prices at all-time highs, lots of folks are buying sterling silver jewelry instead. Did you know that silver is the whitest metal, even whiter than platinum or rhodium? That’s why a flat, polished silver surface makes a perfect mirror. Some silver jewelry is plated with rhodium to prevent tarnish, so you should NOT polish this type of silver, because it will remove the plating! Though rhodium is a platinum-group metal, it is not quite as white as silver, so there are some advantages to leaving the silver au naturale, and we will talk about that in a minute. By the way, the Viridian Gold Jewelry Store will always tell you if one of our jewelry pieces is rhodium-plated, so that you will know how to care for it. Rhodium plating is also commonly used on white gold jewelry.
It doesn’t need regular polishing, because tarnish is kept at bay by skin oils and regular washing. That means that an item worn against the skin, such as a cross on a chain, or a ring, tends to stay relatively tarnish-free. Except when it is exposed to some harsh chemicals which accelerate oxidation. For instance, if you wear a silver neck-cross and go swimming in a chlorinated pool, the cross will quickly turn black! But, swim in a lake or spring-fed pool (like our Barton Springs pool here in Austin!), and nothing happens. Silver is, as the chemists say, “highly reactive”. Some substances besides oxygen, especially sulfur and chlorine, will combine with the silver to form compounds which are black in color. So, if your water supply is high in sulfur (well water is sometimes this way), or is loaded with chlorine, you will have a problem with silver tarnish. And, some folks’ skin oils contain chemicals which can accelerate tarnishing, because of their particular body chemistry or diet.
So, how to clean the polish? Well, you could use silver polish, and that works great–some polishes leave behind a film which helps prevent tarnishing (but that quickly wears off of a piece of jewelry that gets handled). Or, you could do what I do–just put a little toothpaste on your fingers and rub it on the piece, then rinse with water. Quick, convenient and cheap. Remember, though: Don’t polish silver that is rhodium plated. If the silver item is something that is not in constant contact with your skin, such as earrings or a brooch, then you need to make sure you store the jewelry item in an air-tight container or in a tarnish-inhibiting cloth.
