If you've ever bought a diamond before, you probably know how tough of a decision it may be. If you have never bought a diamond before, you may be in for a surprise. Diamond shopping whether for a diamond ring or necklace is no easy task. Below is a basic diamond buying guide to help you with your decision.

1. Buy only from a trusted diamond retailer. Never buy any jewerly or precious stones from a company or someone you don't fully trust or have ever heard about. If you've never heard of them, then it might be safer to steer away from them. This brings us to number two;

2. Use your gut instinct. This may sound simple enough, but this is probably one of the most important things to remember when buying a diamond. If you have a bad feeling, then don't settle, simple as that! Never settle when it comes to jewelry. Only buy what you think you should or only shop from someone you feel good about.

3. Bring a Diamond Guide! Having a Diamond Guide available gives you quick reference when the times are tough. It can provide insight in to a pretty large investment. Don't go unprepared! It may cost you a lot in the long run. The more you know the better off you're going to be, having a guide can be one of the most important things to own when buying a diamond.

4. Know the 4 C's, what they mean and how they are meansured. The four c's of a diamond are Cut, Clarity, Color and Carat Weight. These are the basics on how diamonds are appraised and their initial worth. You should definitely consider this when buying a diamond.

5. Ask to see the apprasial if they have one. Well established diamond retailers may have their diamonds pre-appraised, this can give you insight in to the diamond you are buying. When looking at the appraisal, the price of the diamond should be much lower than the appraised value of the diamond. This is naturally how they are valued. If you buy a diamond just at the appraised value, then you aren't getting that good of a deal.

6. Take lighting in to consideration when buying your next peice of jewelry. Jewelers will often use lights that make precious stones appear much brighter and sparkle much more than they would in normal lighting.

7. Make sure to see if they have a warranty and/or return policy that suites your needs. Knowing this could save you a lot of headache in the long run.

These are just some of the few basic steps to be taken when buying a diamond and possibly the most important. By making a smart buying decision you will create a life-long investment on a product you will appreciate for just as long.
