Diamond clarity: FL/IF/VVS/VS = super expensive, near perfect. SI = best value if you can check a photo for obvious inclusions (defects).
Color: D-G = colorless, expensive, only if you have money to burn. H-J = best value. Can go lower in gold metal settings than white metal.
Cut: Better cut ratings let more light into a diamond, making it sparkle more. Very important property, don't skimp here.

Discerning purchasers of diamonds consider other characteristics of the diamond apart from carat size such as girdle thickness - how big the girdle is can impact on the diameter of a diamond of a certain carat weight.

If you're willing to try a few things to get a bargain, one thing you can try is searching for a diamond which has a strange carat weight, such as 0.96 carats. Often diamonds with these strange carat weights can be picked up for a bargain because they are not as sought-after even though they are practically the same size as the more popular 1.00 carat diamonds. First-time diamond buyers who are in a hurry often just focus on the diamond carat size, which is a big mistake - other properties such as the clarity of the diamond are important in getting a diamond which is attractive not just in terms of its size, but also its appearance.
