Will the diamonds lose its sparkle? If yes, how can i avoid it?

by buying jewlery cleaner! At any jewlery store. As a matter of fact I just cleaned my moms 21 year old wedding ring with the stuff and it was sparkly as ever ;)

Diamonds are a girls best friend! These are the things to look for when shopping for diamonds The color, carat, clarity and cut. There are all kinds of diamonds out there. All diamonds should sparkle, if you get a good quality diamond it will sparkle forever especially if you get it cleaned once in awhile.
