Do you need an appraisal before selling your diamond? If you have taken the time to understand each of the 4 Cs and how they work to answer the question how much is my diamond worth, you are going to enter your transaction with confidence. The market knowledge you have will force a buyer to take you seriously. A diamond appraisal can help augment your knowledge with industry validation for each of the 4 C’s.
A major issue with diamond grading is that, especially when it comes to color and clarity, grading can be subjective. There is no accurate technology readily available that you can simply place a diamond inside and it will give you the exact grade. Diamond grading is done by humans, and humans often see things differently. Even within the GIA, each diamond is evaluated by multiple Graduate Gemologists, and a grade is only given when there is majority agreement.
If you enter a transaction with a diamond buyer with no paperwork, you are leaving it up to them to determine the grade. With so many variables and so much monetary difference between each, you can be certain that you are not going to be able to maximize your diamond’s value.
This is not because a diamond buyer is going to lie, it is because he must be conservative when evaluating and pricing your stone. A diamond with a color of G, is not simply a diamond with a color of G. It can lean closer to F or closer to H. If a diamond buyer gets it wrong, calling a G color diamond an F color, they may not only cost themselves the profit on their investment, but they may even lose money. Clarity is no different. I have met many reputable and honest diamond professionals that refuse to grade diamond clarity any higher than VS2 without a GIA report. This is because the subtleties between a VS2 clarity grade and better are so minute, they are almost undetectable without the proper equipment found in advanced grading laboratories.
So what paperwork should you have to assure you are being given accurate offers? We will discuss the differences between the various diamond certification companies in detail in a future article along with the realities of insurance appraisals. What is important here is to understand that the only diamond grading report that no buyer can argue with is a diamond grading report produced by the Gemological Institute of America. They are the authority in the industry and millions of dollars in diamonds are traded every day based on the GIA reports alone — the actual diamonds never being seen by the buyer. If you do not have a GIA report and want to obtain one for your diamond, GIA makes it very easy for anyone. Simply visit their website at www.GIA.edu. You can also ask the buyer you are dealing with or your local jeweler for assistance, as any reputable diamond professional should be more than willing to help.
