Not all sellers offer diamond grading lab reviews (aka diamond quality reports) to their consumers. So my common suggestions to you is to hold your money in your pocket when dealing with these kinds of jewelers.
Only purchase a diamond engagement ring if it arrives with the original diamond top quality report.
A lab report is an impartial evaluation of the 4Cs of a unfastened diamond and involves a plotted diagram of the stone’s clarity attributes and a graphic illustration of the stone’s proportions. Possessing this sort of a report permits you to examine diamonds of diverse characteristics and in the long run aids you make a far more educated buying determination.
A retailer may possibly lower corners and not supply a lab report or an unscrupulous seller might give a phony one particular simply because of the time, difficulty and price he’ll bear to getting a stone graded.
Yeah – there is a cost for grading a diamond (however that expense is ultimately compensated by the consumer), additionally the shipping and insurance policies expenses for sending the diamond to the lab. And let us not fail to remember the prospect value of a jeweler not having the diamond in his shop for sale for a few weeks although the grading takes place.
Nonetheless, a diamond grading report may also not be accessible since the fees to acquiring a single could influence as well heavily on the last value of the ring.
For case in point, a .3ct diamond ring costing $250 say, may expense around $seventy five to be graded and have the report number inscribed on the girdle on the diamond.
As you research for that best diamond engagement ring for your sweetheart, you’ll locate that there is an alphabet soup of labs proclaiming to supply respected diamond grading reviews. But I would only put my funds on…
The Premier Diamond Grading Lab Reports
Of course, all diamond top quality stories are not designed equal. Inside the business, it is a consensus that the two leading labs are GIA-GTL (Gemological Institute of America’s Gem Trade Lab) and the AGS (American Gem Culture Laboratories).
The GCAL (Gem Certification and Assurance Lab) also gives very regarded reports or “diamond certificates” as they are referred to by GCAL.
The GIA has the strongest international reputation for independence and regularity. Owing to their constant colour and clarity strictness guidelines, the globe’s biggest and most costly diamonds have been sent there for grading a long time. In 2006, GIA-GTL included a two-dimensional cut grading method for spherical outstanding diamonds.
AGS makes use of the strictest minimize standards in the market. It makes use of a three-dimensional light performance metric that can grade numerous diamond styles. In truth, it is the only minimize grading system that is recognized by the scientific community.
What is a lot more, its Diamond Quality Doc makes use of a special and proprietary to 10 grading technique to appraise the 4 Cs – a program which is less difficult to understand than GIA’s grading technique. In simple fact, AGS even goes the added stage by equating their -ten rating scale to other varieties of score.
For instance, the traditional VS1 diamond clarity score is a 3 on the AGS Diamond Quality Document.
Diamond Reporting – The Negatives
one. Diamond grading is not standardized or regulated and consequently you could appear throughout tier 2 labs that employ looser recommendations to the tier 1 grading labs pointed out over.
If you purchase a diamond that has been graded by a tier 2 lab, you may stop up paying out much more for a lesser good quality diamond. So for example, a diamond rated a “F” in colour at a tier two lab may get a G, H, or lower shade rating at a more respected lab.
The industry also discounts diamonds graded by lesser acknowledged labs by about fifteen-thirty% or much more. So possibly you only get a diamond graded by a tier one lab or you acknowledge that you might be acquiring a lesser high quality diamond than what is mentioned on the report if that diamond is graded by a lesser known lab.
2. Numerous massive chain shops have massive contracts with lesser recognized labs with “softer” diamond grading tips. Some of these softer labs set “suggested replacement values” on the lab reviews – values which are increased than what stores intends offer the diamonds for.
So a salesperson in a chain keep may say to you, “Search at the excellent deal you are obtaining below. We are offering you this diamond engagement ring for $2500 but the report suggests that the suggested substitute price is $4000.” Wow – what a offer – NOT! This is why it is far better that you have confidence in only unbiased tier 1 labs.
Also bear in mind that trustworthy diamond grading stories are not appraisals and never provide appraisal figures. Diamond appraisals are often grossly inflated and are not one thing you may want to count on.
3. Diamond studies are riddled with disclaimers that specify that absolutely nothing is “qualified” or confirmed and that the labs are not accountable for mistakes. In fact, the GIA offers a disclaimer of sorts on their internet site relating to the use of the phrase “certify.” The site states:
“It is incorrect to condition that pupils, graduates, their organizations, or certain gemstones are “accredited” by GIA. The Gemological Institute of The us does not certify any individual or everything. Neither a pupil nor a graduate who has been awarded a certification or diploma, nor a gem which has been graded or recognized by GIA has been qualified by GIA”.
So it is possible that you the buyer is still left keeping the bag ought to an inaccuracy in a report is afterwards uncovered. Courts have regularly ruled that sellers, not labs, are liable for such errors. Why? Since the labs indicated beforehand that their stories could not be held liable.
Fortunately, there are a few ways to give yourself far more consumer security:
A. You could fly to India where jewelers provide a life span buyback coverage to their consumers. Way too expensive to fly?
B. You could locate 1 of the 20% of US jewelers who offer totally bonded diamonds. These are diamonds that are marketed with life span breakage, lifetime trade-in and lifetime buyback insurance policies.
C. Not as excellent a cure as purchasing a entirely bonded diamond but you could buy a diamond that arrives with an actual “certification” and not a report. “Certified diamonds do occur with guaranties” albeit for shorter durations.
Some sellers refer to a “diamond report” as a “qualified diamond” but technically this is not right. From a legal standpoint, a diamond report is a just an skilled viewpoint even though in actuality, aspects of a diamond grading report are not just viewpoints.
For example, a diamond’s carat (bodyweight) can be accurately decided as properly as its cut grade by measuring its optical efficiency or by referring to a pc product. A certificate on the other hand is a assertion of truth – a document for which the issuer accepts lawful accountability and will make restitution to the consumer for blunders.
Some best diamond grading labs offer each reviews and certificates. AGS gives Diamond Quality Files (non-accredited reports) and also Diamond Quality Certificates. Diamond Top quality Certificates are ready solely for AGS retail jewelers and gives guaranties from taking part American Gem Culture member stores.
GCAL certifies it is diamond grading also. Its one hundred% money-again guarantee policy is valid for a time period of two many years from the day on the relevant certificate. This plan ensures the accuracy of the minimize, coloration and clarity grades and the carat fat.
A report or certification need to will have a number on it that might or might not be inscribed on a diamond. You will be able to enter that quantity on the site of the certifying lab to examine a report’s validity.
Components Of A Diamond Grading Report
Diamond grading reports are usually evolving but certain aspect should continue to be the same. For instance, the:
The Report #. This amount is presented and recorded in a lab’s document and could or may possibly not be inscribed on a diamond’s girdle. You can enter the report number on a grading lab’s website to check out the authenticity of the diamond quality report or to get more information about the diamond.

Carat Weight: The bodyweight of a diamond is measured to the hundredth of a carat and some even offer such evaluate to the thousandth of a carat (1.123ct.). Carat is the most objective and the least difficult to realize of the 4Cs since all one particular has to do is excess weight the stone.
Color Grade: This tells you the degree of color absence in the diamond. The less color the greater the grade.
Diamonds are usually graded from D-Z the nearer to “D” the whiter the diamond. You must never ever see diamond colour range this kind of as (G-H, I-J-K, and so on) on a diamond report. You need to only see colour ranges on appraisals for stones that are mounted.
