Learn how to get the best deal

 

Certified Diamonds

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.

Selling “certified” diamonds has become a popular practice with certain diamond merchants and dealers in Utah. “Certification” means sending a diamond to a “neutral” gem lab to establish the grade of the stone.

 

There are many grading labs that will give an opinion of a diamond grade for a fee, complete with an official looking document. To the unwary, it appears to be a guarantee of what you’re buying.

 

However, many of these certificates are not legitimate because these merchants have purposely avoided having their diamonds graded according to the industry standard for diamonds, which is the Gemological Institute of America (GIA).

What is certification anyway?

A legitimately authenticated diamond is one that has been sent to the Gemological Institute of America (GIA) to be graded. GIA is a non-profit organization that established the worldwide standards for diamond grading in 1933. In addition, GIA also provides courses and administers degrees for all gemology titles worldwide. “Certification” as now used means that any of a number of non-GIA labs have given their opinion on a diamond and issued a “certificate”.

Where do these non-GIA labs get their credentials?

They take courses from GIA, just like any other jeweler with credentials. However, they do not have the authority to ratify diamond grades on behalf of GIA.

Do all labs grade the same?

Absolutely not, even though all use the same grading terms to sound authoritative.

 

The problem is that all labs (except GIA) rely on the profit from certificate sales to stay in business, which compromises their impartiality. These labs must keep clients (diamond merchants) happy by giving higher grades than the GIA would, making a diamond appear better on paper than it actually is.

 

On the other hand, GIA is a non-profit organization and has no such conflict of interest created by a profit motive. This is why you can trust a GIA Diamond Grading Report. After all, GIA established the grading system.

Why do stores use non-GIA grading reports?

Why would a dealer use a non-GIA lab when GIA charges the same as other labs and takes the same time to do the grading report? This is a question you ought to ask yourself when considering a “certified” diamond. The simple truth is that merchants use non-GIA labs because those labs give poor diamonds better grades than they actually should get.

 

Is a “certificate” a guarantee of quality?

 

Not at all. In fact, all certificates have strong disclaimers stating they do not guarantee anything! A typical fine print example:

 

“This report expresses an opinion at the time of examination of the stone. It is not a guarantee, a valuation, or an appraisal of any kind. [This grading lab ] has made no representation or warranty regarding this report or the diamond described.”

 

Merchants in Utah that use non-GIA reports are in fact saying “you can’t trust our grading so we’re going to ask you to trust this third party (whom you know nothing about), and this third party will not guarantee it either”!

Do I need a certificate to make an informed purchase?

No, unless you feel you can’t trust the merchant in consideration. In that case you should insist on a GIA Diamond Grading Report. However, a good jeweler will show you how to confirm diamond grades without a certificate, as well as have diamonds in stock with GIA Diamond Grading Reports, if you so desire.

 

AGS reports are just as valid and authentic as GIA reports, for many of the same reasons that make GIA reporting credible. In fact, AGS reports (called Diamond Quality Documents) give more details about the cut grade than GIA reports do.

 

However, don’t confuse an AGS report with an AGS Member Jeweler. An AGS Member Jeweler does not have power to validate grades on behalf of AGS, or issue an official AGS report.

 

True AGS reports are rarely used in this area.

So, how do I know what I'm buying?

Whether you’re shopping for a diamond with or without a GIA (or AGS) report, ask the jeweler to show you how each grade was determined on special gemological equipment. A good jeweler will make diamond grading clear, a poor jeweler will confuse you.
