Diamond Certificate Authenticity
Remember, your grading certificate is only as good as the laboratory that issued it, so it's worth checking that all of the following details are included:
Authorship - Check out the grading lab's credentials.
Date - A current date issued at the time of inspection will help ensure that the diamond has not been altered (e.g set in a ring or piece of jewelry and/or previously worn).
Cut - Check this evaluation has been done on the actual diamond, not a model. - Find out more about Diamond Cut.
Carat - This refers to the weight of the diamond and not the actual size of the diamond. - Find out more about Diamond Carat.
Measurements - Evaluate the measurements. For round diamonds, the proportions are important whilst for fancy-cut diamonds the length-to-width ratio is of more importance. - Find out more about Measurements.
Clarity - It's important to note that clarity gradings vary between grading labs but if you shop 'like for like' using reports issued by the same laboratories, you should end up with the diamonds you want. - Find out more about Diamond Clarity.
Color - Again, grading systems can vary but generally colorless diamonds are the most expensive and desirable. (Rare diamonds of intense and vivid coloring are highly prized and therefore extremely expensive.) - Find out more about Diamond Color.
Proportions - Check the depth of the diamond - the desired depth percentage depends on the shape of the diamonds. This should also include information about the table width, girdle and culet.
Finish - Look for 'good' or better gradings for polish and symmetry.
