Purchase only lab-graded diamonds
If you’ve arrived at this blog article, you’re undoubtedly looking for a beautiful diamond. You may be considering purchasing an engagement ring or upgrading an existing one to a bigger diamond. It may be daunting when you educate yourself in order to make the best choice about which diamond to purchase. There are many factors to consider. Which diamond size, color, and clarity should I purchase? What impact does the cut have on the brilliance and price? Do I purchase a laboratory graded (often referred to as lab certified) diamond? That last question is a resounding YES.
As you are undoubtedly aware, the color, clarity, cut grade, and carat weight of a diamond all influence its value. On a bigger diamond, altering the color or clarity by only one grade may have a significant effect on the price. As a result, it is critical that you purchase a diamond that has been evaluated by an independent diamond grading laboratory, rather than the jewelry shop where it is being sold.
Purchasing a diamond that has been “house graded” is a very poor idea for you. Grading is always biased in favor of the home and is often less accurate than it should be. Consider purchasing an “H” color, “VS2” clarity diamond and then attempting to sell it only to discover that it is really a “J” color, “SI2” clarity diamond. This does occur, and it is heartbreaking.
You’ve concluded that you’d best invest in a lab-graded diamond. There are a plethora of diamond labs available. Several of them generate diamond grading reports that are unworthy of the paper on which they are printed. To safeguard your diamond investment, you should avoid labs other than the GIA (Gemological Institute of America), EGL USA (European Gemological Laboratory), and AGS (American Gem Society) (American Gem Society). Due to the scarcity of AGS-graded diamonds on the market, we shall limit our discussion to GIA and EGL USA.
GIA Diamonds Laboratory in Modesto, CAEGL USA
Which Laboratory Is Superior?
Simply put, it is GIA. They have the greatest reputation for diamond grading accuracy. A diamond graded by GIA will demand a premium over a diamond graded by EGL USA. Not just when you purchase it, but also when you sell or trade it in. You’ll get much more for it.
Why are GIA-certified diamonds more valuable? Because the diamond industry is well aware that the GIA’s grading standards are much more stringent than those of EGL USA. As a result, they are more valuable. For instance, suppose you’re looking for a 1.50ct round diamond with a G color, SI1 clarity, and an Excellent cut. And you’re comparing a GIA-rated diamond with one graded by EGL USA. You’ll soon see that the GIA costs about $13,000 and the EGL USA costs approximately $10,000. That’s a 30% increase for the GIA! The jeweler is not profiting more from the GIA. It’s just that wholesalers demand a premium for GIA-certified diamonds. Why? Because the two diamonds will not be of the same quality – despite the fact that both reports indicate they are.
Ascertain for yourself. Visit our Modesto Loose Diamond Search page to do a diamond search. At the bottom, ensure that you tick both “GIA” and “EGLUSA”. Consider the pricing differentials. Bear in mind that you get what you pay for.
If you submit the EGL USA 1.50ct stated above to GIA for a diamond report, you will understand why the price discrepancy exists. I’ve done so many times. It is customary for GIA to downgrade this “H” color diamond by one or two color grades – it would most likely get a “J” color grade. And the clarity would be reduced by at least one grade, most likely to an “SI2” in this instance. Even if the documents state otherwise, they are not identical. That is why the EGL USA stone will be less expensive.
GIA diamond vs. EGL diamond
It’s not a bad bargain to get the EGL diamond; just don’t expect it to compare to a GIA diamond of the same grade – it won’t. Assume that the color grade will be about two grades lower and the clarity grade will be one grade lower than the GIA rating. Additionally, you can anticipate paying much less (20% – 35% less) for the EGL diamond.
If you have the opportunity, it’s interesting to compare two similarly graded diamonds side by side and observe for yourself the difference between the two laboratories.
Avoid These EGL Locations
This is critical information. There are many worldwide EGL diamond laboratories, each of which operates independently. The EGL USA is an established laboratory. However, EGL Europe, EGL Canada, and EGL Israel all have a dreadful reputation for flagrant grade inflation. They were so terrible that they were sued for fraud. Even jewelers that sell these overgrazed diamonds have been sued, and our diamond purchasing community Polygon has prohibited the sale of diamonds with these reports. Any jeweler who sells you a diamond that has one of these reports is untrustworthy. Run.
If you are purchasing a diamond and are unconcerned with the “certificate’s” quality being one or two grades wrong, EGL USA may be sufficient. However, if you are more concerned with quality and need rigorous grading on your diamond, you should stay with GIA. You’re going to be happy you did.
