How to make fake diamond earrings look real?

I have these really cute fake diamond earrings, but they look too fake. How do you make them look more real?|||I don't know how to make those particular earrings look real, but I have found that when buying diamond simulants, it's best to get them in a gold (white or yellow) setting. This kind of makes it hard to tell if it is or isn't real.|||Why do they look so obviously fake? Are they large and gaudy? Maybe you should wear smaller fake diamonds, as real ones are usually smaller and don't shout for attention. To make them really sparkle, soak them in a solution of water to which has been added a few drops of dish detergent and ammonia. Some fake gemstones can really fool people if they are of a discreetly smaller size.|||Keep them very clean and windex or ammonia will help do that.
