Not all sellers present diamond grading lab experiences (aka diamond high quality experiences) to their shoppers. So my basic recommendation to you is to maintain your cash in your pocket when coping with such jewelers.
Solely buy a diamond engagement ring if it comes with the unique diamond high quality report.
A lab report is an impartial analysis of the 4Cs of a unfastened diamond and features a plotted diagram of the stone’s readability traits and a graphic illustration of the stone’s proportions. Having such a report means that you can examine diamonds of various qualities and finally helps you make a extra knowledgeable shopping for resolution.
A retailer could lower corners and never present a lab report or an unscrupulous vendor could present a faux one due to the time, hassle and what is an expense report he’ll bear to getting a stone graded.
Yeah – there’s a worth for grading a diamond (although that price is finally paid by the patron), plus the transport and insurance coverage expenses for sending the diamond to the lab. And allow us to not overlook the chance price of a jeweler not having the diamond in his retailer on the market for just a few weeks whereas the grading takes place.
Nonetheless, a diamond grading report may not be accessible as a result of the prices to getting one could impression too closely on the ultimate worth of the ring.
For instance, a Zero.3ct diamond ring costing $250 say, could price round $75 to be graded and have the report quantity inscribed on the girdle on the diamond.
As you seek for that splendid diamond engagement ring on your sweetheart, you will discover that there’s an alphabet soup of labs claiming to supply respected diamond grading experiences. However I might solely put my cash on…
The Premier Diamond Grading Lab Experiences
Sure, all diamond high quality experiences should not created equal. Throughout the trade, it’s a consensus that the 2 premier labs are GIA-GTL (Gemological Institute of America’s Gem Commerce Lab) and the AGS (American Gem Society Laboratories).
The GCAL (Gem Certification and Assurance Lab) additionally provides extremely regarded experiences or “diamond certificates” as they’re referred to by GCAL.
The GIA has the strongest world popularity for independence and consistency. As a consequence of their fixed coloration and readability strictness pointers, the globe’s largest and costliest diamonds have been despatched there for grading a long time. In 2006, GIA-GTL added a two-dimensional lower grading system for spherical good diamonds.
AGS makes use of the strictest lower requirements within the trade. It makes use of a three-dimensional gentle efficiency metric that may grade a number of diamond shapes. In truth, it’s the solely lower grading system that’s acknowledged by the scientific group.
What’s extra, its Diamond High quality Doc makes use of a singular and proprietary Zero to 10 grading system to guage the four Cs – a system which is simpler to grasp than GIA’s grading system. In truth, AGS even goes the additional step by equating their Zero-10 ranking scale to different types of ranking.
For instance, the traditional VS1 diamond readability ranking is a three on the AGS Diamond High quality Doc.
Diamond Reporting – The Drawbacks
1. Diamond grading is just not standardized or regulated and therefore chances are you’ll come throughout tier 2 labs that make use of looser pointers to the tier 1 grading labs talked about above.
When you purchase a diamond that has been graded by a tier 2 lab, chances are you’ll find yourself paying extra for a lesser high quality diamond. So for instance, a diamond rated a “F” in coloration at a tier 2 lab could get a G, H, or decrease coloration ranking at a extra respected lab.
The trade additionally reductions diamonds graded by lesser recognized labs by about 15-30% or extra. So both you solely purchase a diamond graded by a tier 1 lab otherwise you settle for that you simply is likely to be shopping for a lesser high quality diamond than what’s acknowledged on the report if that diamond is graded by a lesser recognized lab.
2. Many massive chain shops have large contracts with lesser recognized labs with “softer” diamond grading pointers. A few of these softer labs put “prompt substitute values” on the lab experiences – values that are larger than what shops intends promote the diamonds for.
So a salesman in a series retailer could say to you, “Have a look at the good deal you might be getting right here. We’re promoting you this diamond engagement ring for $2500 however the report says that the prompt substitute worth is $4000.” Wow – what a deal – NOT! For this reason it’s higher that you simply belief solely impartial tier 1 labs.
Additionally keep in mind that respected diamond grading experiences should not value determinations and do not supply appraisal figures. Diamond value determinations are sometimes grossly inflated and should not one thing you will wish to depend on.
three. Diamond experiences are riddled with disclaimers that specify that nothing is “licensed” or assured and that the labs should not accountable for errors. In truth, the GIA provides a disclaimer of kinds on their web site concerning the usage of the phrase “certify.” The web site says:
“It’s incorrect to state that college students, graduates, their companies, or specific gem stones are “licensed” by GIA. The Gemological Institute of America doesn’t certify anybody or something. Neither a pupil nor a graduate who has been awarded a certificates or diploma, nor a gem which has been graded or recognized by GIA has been licensed by GIA”.
So it’s attainable that you simply the patron is left holding the bag ought to an inaccuracy in a report is later found. Courts have steadily dominated that sellers, not labs, are answerable for such errors. Why? As a result of the labs indicated beforehand that their experiences could not be held liable.
Luckily, there are a pair methods to present your self extra purchaser safety:
A. You could possibly fly to India the place jewelers supply a lifetime buyback coverage to their clients. Too costly to fly?
B. You could possibly discover one of many 20% of US jewelers who promote totally bonded diamonds. These are diamonds which can be offered with lifetime breakage, lifetime trade-in and lifelong buyback insurance policies.
C. Not nearly as good a treatment as shopping for a completely bonded diamond however you would purchase a diamond that comes with an precise “certificates” and never a report. “Licensed diamonds do include guaranties” albeit for shorter durations.
Some sellers check with a “diamond report” as a “licensed diamond” however technically this isn’t right. From a authorized standpoint, a diamond report is a merely an professional opinion although genuinely, points of a diamond grading report should not simply opinions.
For instance, a diamond’s carat (weight) may be precisely decided in addition to its lower grade by measuring its optical effectivity or by referring to a pc mannequin. A certificates however is an announcement of reality – a doc for which the issuer accepts obligation and can make restitution to the patron for errors.
Some high diamond grading labs supply each experiences and certificates. AGS provides Diamond High quality Paperwork (non-certified experiences) and likewise Diamond High quality Certificates. Diamond High quality Certificates are ready completely for AGS retail jewelers and provides guaranties from taking part American Gem Society member shops.
GCAL certifies it is diamond grading additionally. Its 100% money-back assure coverage is legitimate for a interval of two years from the date on the relevant certificates. This coverage ensures the accuracy of the lower, coloration and readability grades and the carat weight.
A report or certificates ought to can have a quantity on it which will or might not be inscribed on a diamond. It is possible for you to to enter that quantity on the web site of the certifying lab to test a report’s validity.
Components Of A Diamond Grading Report
