Did you know.............

.... If you have a strand of natural pearls you need to treat them carefully! Don't get them wet - it will rot the thread, and penetrate into the holes in the pearls, damaging them. Also keep them away from perfume - it can damage the surface lustre. The best way to clean them is with a soft cloth, like microfibre, but not spectacle cloths, as they are impregnated with chemicals that will harm the pearls.

 

.... People have long thought that testing a gem by seeing if it will scratch glass is proof it is a diamond. In fact any stone that is harder than glass will scratch it - this would include topaz, beryl (eg emerald, aquamarine etc), and sapphire. There are white forms of all these gems, and they will all scratch glass. 

 

.... It is widely believed that if you wear a 9ct ring next to an 18ct ring then the 9ct one will wear away the 18ct one. This is completely wrong - each metal will always wear at it's characteristic rate, regardless of what is next to it. The truth is that the 9ct ring will RESIST wear better than the 18ct one, as it is harder.

 

.... Wearing your chains and bracelets while exercising will speed up the wear on the links. Dust between the links is abrasive, so running around and making your chains swing about will contribute to the wear on them and shorten their life.

 

 .... Contrary to popular belief, diamonds are not immune to damage - they are the hardest natural substance, but they are still originally a crystal, and if hit hard enough on the wrong angle it is quite possible to chip or even break them.
