Learn how to get the best deal


Diamond Grading

No matter where you shop, every store will claim they have the best price. So who actually does and how do you know? At Wilson Diamonds, we’ll help you become an expert so you can find the best deal on your own.

Diamond grades are supposed to be standard. Unfortunately it is not uncommon to find vastly different interpretations of grades, usually inflated in the jewelers favor.


To sort through these inconsistencies you must ask the jeweler to verify any verbal quotes by showing you the diamond under 10x magnification and supplying you with a diamond report from a well known 3rd party. This is the best way to know the actual grade and be able to accurately compare prices.


In this section are some highly recommended rules to avoid selecting poor diamonds that initially appear better than they are. Follow these rules and you’ll make a much better choice than when you copy down quoted grades and try to compare jewelers.


Diamond Grading Rules


Rule: Never buy a mounted diamond (already set in the ring); it’s far to easy to hide imperfections (inclusions).


Diamond quality is defined by four grading criteria, called the Four C’s: Cut, Color, Clarity, and Carat-Weight. A diamond is given a separate grade in each category. Some of these categories affect beauty a great deal, others very little, but all categories affect price. Even slight nuances can have an effect on price, especially with regards to bigger diamonds.


Rule: When comparing diamonds, never allow one of the four grading categories to go unmentioned, undefined, or casually glossed over. Especially pay attention that the cut grade is defined as a GIA grade.


The Four C’s were invented by the Gemological Institute of America (GIA), a non profit organization that does impartial grading of diamonds and offers education and diplomas in diamond grading.
