Not all sellers supply diamond grading lab reports (aka diamond good quality stories) to their consumers. So my standard guidance to you is to hold your income in your pocket when dealing with this kind of jewelers 對戒.
Only acquire a diamond engagement ring if it will come with the original diamond top quality report.
A lab report is an unbiased evaluation of the 4Cs of a unfastened diamond and contains a plotted diagram of the stone’s clarity traits and a graphic representation of the stone’s proportions. Having such a report enables you to examine diamonds of diverse qualities and in the long run will help you make a a lot more educated buying selection.
A retailer might reduce corners and not supply a lab report or an unscrupulous vendor might provide a bogus 1 due to the fact of the time, difficulties and cost he’ll bear to receiving a stone graded.
Yeah – there is a price tag for grading a diamond (however that value is ultimately paid out by the customer), furthermore the delivery and insurance policy fees for sending the diamond to the lab. And allow us not neglect the chance cost of a jeweler not possessing the diamond in his store for sale for a handful of months whilst the grading will take location.
Nonetheless, a diamond grading report may also not be available since the costs to getting 1 might affect too intensely on the ultimate value of the ring.
For illustration, a .3ct diamond ring costing $250 say, may price all around $75 to be graded and have the report number inscribed on the girdle on the diamond.
As you look for for that best diamond engagement ring for your sweetheart, you’ll find that there is an alphabet soup of labs claiming to provide respected diamond grading stories. But I would only place my cash on…
The Leading Diamond Grading Lab Studies
Sure, all diamond quality reviews are not created equal. In 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 Modern society Laboratories).
The GCAL (Gem Certification and Assurance Lab) also gives highly regarded reviews or “diamond certificates” as they are referred to by GCAL.
The GIA has the strongest global reputation for independence and regularity. Thanks to their consistent color and clarity strictness suggestions, the globe’s greatest and most expensive diamonds have been sent there for grading a long time. In 2006, GIA-GTL extra a two-dimensional lower grading technique for round brilliant diamonds.
AGS employs the strictest minimize expectations in the industry. It utilizes a three-dimensional light performance metric that can quality many diamond styles. In reality, it is the only reduce grading technique that is recognized by the scientific local community.
What is much more, its Diamond Good quality Doc makes use of a unique and proprietary to ten grading technique to appraise the four Cs – a system which is less difficult to understand than GIA’s grading technique. In simple fact, AGS even goes the extra action by equating their -ten score scale to other forms of score.
For case in point, the typical VS1 diamond clarity ranking is a three on the AGS Diamond Quality Doc.
Diamond Reporting – The Drawbacks
1. Diamond grading is not standardized or regulated and therefore you might occur across tier 2 labs that utilize looser guidelines to the tier 1 grading labs talked about above.
If you acquire a diamond that has been graded by a tier two lab, you may possibly finish up having to pay more for a lesser high quality diamond. So for illustration, a diamond rated a “F” in shade at a tier 2 lab may possibly get a G, H, or decrease shade ranking at a a lot more trustworthy lab.
The sector also discounts diamonds graded by lesser identified labs by about fifteen-30% or a lot more. So both you only get a diamond graded by a tier 1 lab or you take that you might be buying a lesser good quality diamond than what is mentioned on the report if that diamond is graded by a lesser recognized lab.
2. A lot of large chain retailers have massive contracts with lesser known labs with “softer” diamond grading recommendations. Some of these softer labs place “advised substitution values” on the lab reviews – values which are larger than what stores intends sell the diamonds for.
So a salesperson in a chain keep might say to you, “Search at the excellent offer you are getting below. We are promoting you this diamond engagement ring for $2500 but the report states that the recommended substitute value is $4000.” Wow – what a deal – NOT! This is why it is far better that you have confidence in only independent tier 1 labs.
Also bear in mind that trustworthy diamond grading reports are not appraisals and will not provide appraisal figures. Diamond appraisals are usually grossly inflated and are not one thing you’ll want to count on.
3. Diamond reports are riddled with disclaimers that specify that nothing is “accredited” or assured and that the labs are not accountable for errors. In simple fact, the GIA delivers a disclaimer of types on their web site with regards to the use of the word “certify.” The site suggests:
“It is incorrect to condition that pupils, graduates, their firms, or particular gemstones are “certified” by GIA. The Gemological Institute of America does not certify anybody or anything. Neither a college student 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 attainable that you the consumer is remaining holding the bag should an inaccuracy in a report is afterwards identified. Courts have regularly ruled that sellers, not labs, are liable for this kind of mistakes. Why? Since the labs indicated beforehand that their stories couldn’t be held liable.
Thankfully, there are a pair techniques to give your self a lot more consumer security:
A. You could fly to India the place jewelers offer you a life span buyback coverage to their clients. As well pricey to fly?
B. You could locate one particular of the 20% of US jewelers who market fully bonded diamonds. These are diamonds that are sold with lifetime breakage, life span trade-in and lifetime buyback procedures.
C. Not as good a cure as getting a totally bonded diamond but you could buy a diamond that will come with an actual “certification” and not a report. “Accredited diamonds do occur with guaranties” albeit for shorter durations.
Certification
Some sellers refer to a “diamond report” as a “licensed diamond” but technically this is not correct. From a lawful standpoint, a diamond report is a basically an specialist viewpoint even though in actuality, factors of a diamond grading report are not just thoughts.
For example, a diamond’s carat (fat) can be correctly identified as well as its reduce grade by measuring its optical effectiveness or by referring to a laptop model. A certificate on the other hand is a statement of fact – a document for which the issuer accepts authorized responsibility and will make restitution to the buyer for problems.
Some top diamond grading labs offer you equally studies and certificates. AGS offers Diamond Quality Paperwork (non-qualified reviews) and also Diamond Good quality Certificates. Diamond Good quality Certificates are prepared exclusively for AGS retail jewelers and offers guaranties from taking part American Gem Modern society member retailers.
GCAL certifies it’s diamond grading also. Its a hundred% money-again promise plan is legitimate for a period of time of two years from the date on the applicable certificate. This plan assures the precision of the reduce, coloration and clarity grades and the carat bodyweight.
A report or certification must will have a variety on it that might or might not be inscribed on a diamond. You will be in a position to enter that quantity on the web site of the certifying lab to verify a report’s validity.
Elements Of A Diamond Grading Report
Diamond grading reports are always evolving but particular component ought to continue to be the exact same. For occasion, the:
The Report #. This variety is offered and recorded in a lab’s file and may possibly or might not be inscribed on a diamond’s girdle. You can enter the report variety on a grading lab’s site to check out the authenticity of the diamond high quality report or to get more details about the diamond.

Carat Excess weight: The excess weight of a diamond is measured to the hundredth of a carat and some even give such evaluate to the thousandth of a carat (one.123ct.). Carat is the most objective and the simplest to recognize of the 4Cs since all one particular has to do is bodyweight the stone.
Coloration Grade: This tells you the degree of coloration absence in the diamond. The much less shade the higher the quality.
Diamonds are usually graded from D-Z the closer to “D” the whiter the diamond. You must in no way see diamond color selection these kinds of as (G-H, I-J-K, and so on) on a diamond report. You should only see shade ranges on appraisals for stones that are mounted.
