The bigger the better, a lot of people say. When a jeweler tells you that you have a five carat diamond ring, don't get dazzled by the carats. If there was only one stone then you'd have no problem. You might actually be getting a 1 carat diamond surrounded by eight half-carat smaller pieces.

An honest jeweler will tell you the weight of each stone in the ring separate from the center diamond. In fact he'll even give you a certificate from a reputed lab such as the Gemological Institute of America (GIA) as proof. If he can't or won't do these, you're better off buying from someone else.

Then there's the bait and switch. The jewelry store will advertise a diamond at a great price. Problem is that when you get there, they'll tell you that it's already been sold and try to convince you to get another piece instead. Rarely is this case true. Usually there was never such a piece and they'll show you something more expensive that they will try to get you to buy instead.

If the diamond that they announced for sale isn't available, ask for another just like it. If they can't produce another one of the same special quality and price, you are better off walking out the door. Don't let them get your hard earned money.

Normally when you go to a jewelry shop, the gems are lying on a beautiful cloth bed under bright lights. The gems are so white and tempting. Hold it right there! Most diamonds really will look whiter especially under lights that give off a certain blue component. If you really want to check the color of a stone, check it in sunlight. If they refuse, refuse to purchase as well.

You were finally able to find the gem that symbolizes your love. You ask your jeweler t o know make it into a ring so that you can propose to your beloved. He said that you would have to leave it with him for a few weeks and he'll call you when it's ready.

When the ring arrives, it is beautiful but….something about it just doesn't feel right. You can't quite put your finger on it but this doesn't seem to be the diamond that you bought. How can you tell?

The solution is simple: have the diamond checked by an independent gemologist certified by a group such as the GIA. Have them compare it to the certificate of your diamond to confirm that it is a match. After all, no two diamonds are exactly the same. Then you'll know and can demand proper action.

Bottom line, to avoid scams you should take the time to educate yourself about the basics of diamonds. Next you'll need to find a jeweler or gemologist that you can truly trust. Lastly, always ensure that you are given the proper certificate for your gem, one issued by the Gemological Institute of America (GIA) or another reputed independent lab. These will save you a whole lot of money and avoid giving you headaches.
