Why buy GIA certified?
You probably already know that each diamond is qualified and priced according to the four "C's" (cut, color, clarity and carat weight), but have you ever wondered who grades the diamond a sales person
shows you? In other words, how do you know a diamond shown to you as F color and VS2 clarity is really an F color, VS2 clarity diamond?
Let's assume that you purchase a diamond graded as 1.26 carats, F color and VS2 clarity from us at JH Faske Jewelers. To ensure that our grading of the diamond is correct, you decide to take it to ten different diamond appraisers. You will probably find that the ten appraisers give you at least six different combinations of grades, all of which might differ from the appraisal you received at JH Faske Company. Does this mean that JH Faske Jewelers lied to you, and sold the diamond to you in an unethical or deceptive manner? Maybe JH Faske Jewelers assessment of the diamond was correct and the other jewelers grading was slightly off. How can you compare diamond prices objectively if the same diamond can receive varying grades by several different appraisers?
Now you probably understand what a typical shopper has to go through in pursuit of that special diamond. Isn't there a better and simpler way of doing this? YES, THERE IS! Shop for a diamond that has been certified, not by just anyone, but by the GIA(Gemological Institute of America). All diamond experts and jewelers know what a "GIA certificate" is. The GIA's grading is undeniably recognized throughout the jewelry industry as the most accurate and unbiased opinion when it comes to grading diamonds.

Comparing prices of diamonds with GIA certificates eliminates many of the questions of clarity and color. Having said this, don’t think you can buy a stone totally based upon the certificate. Other factors such as location of the inclusions, table and depth percentages (cut), are huge factors in the pricing of the stone.
It is best to view a minimum of two to three stones, loose (not set in a mounting) to really see the difference. Many websites selling diamonds now state a cut grade for all diamonds they sell. The reality is that GIA will only put a cut grade on a round, brilliant cut diamond. All other cut grades are a matter of opinion of the person selling you the diamond. The best way to buy a diamond is to find a reputable, independent jeweler that can show you loose stones side by side and also be there to service and guarantee the piece of jewelry your diamond is set in.
