Study The Diamond Grading Report Just before Buying An Engagement Ring

Not all sellers supply diamond grading lab studies (aka diamond top quality reports) to their customers. So my standard suggestions to you is to maintain your funds in your pocket when working with such jewelers.

Only purchase a diamond engagement ring if it arrives with the first diamond high quality report.

A lab report is an independent analysis of the 4Cs of a free diamond and involves a plotted diagram of the stone’s clarity qualities and a graphic representation of the stone’s proportions. Possessing such a report permits you to examine diamonds of distinct attributes and eventually will help you make a more informed getting choice.

A retailer could lower corners and not provide a lab report or an unscrupulous seller could offer a phony a single because of the time, trouble and expenditure he’ll bear to acquiring a stone graded.

Yeah – there is a price for grading a diamond (though that value is at some point compensated by the customer), in addition the shipping and delivery and insurance expenses for sending the diamond to the lab. And permit us not neglect the prospect expense of a jeweler not possessing the diamond in his store for sale for a few weeks while the grading takes location.

However, a diamond grading report might also not be accessible due to the fact the costs to receiving one may affect also heavily on the ultimate price tag of the ring.

For instance, a .3ct diamond ring costing $250 say, may possibly price all around $seventy five to be graded and have the report variety inscribed on the girdle on the diamond.

As you search for that best diamond engagement ring for your sweetheart, you’ll discover that there is an alphabet soup of labs declaring to offer trustworthy diamond grading stories. But I would only set my money on…

The Premier Diamond Grading Lab Stories

Sure, all diamond high quality studies are not created equivalent. Within the sector, it is a consensus that the two premier 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 delivers hugely regarded studies or “diamond certificates” as they are referred to by GCAL.

The GIA has the strongest worldwide popularity for independence and consistency. Thanks to their consistent colour and clarity strictness tips, the globe’s greatest and most costly diamonds have been sent there for grading many years. In 2006, GIA-GTL added a two-dimensional reduce grading technique for spherical amazing diamonds.

AGS utilizes the strictest minimize requirements in the market. It employs a a few-dimensional light-weight efficiency metric that can grade numerous diamond styles. In simple fact, it is the only reduce grading program that is identified by the scientific group.

What is more, its Diamond Top quality Doc makes use of a distinctive and proprietary to 10 grading method to evaluate the 4 Cs – a program which is easier to understand than GIA’s grading system. In simple fact, AGS even goes the added stage by equating their -ten score scale to other kinds of ranking.

For example, the typical VS1 diamond clarity rating is a three on the AGS Diamond High quality Doc.

Diamond Reporting – The Drawbacks

1. Diamond grading is not standardized or controlled and consequently you may come across tier two labs that utilize looser suggestions to the tier one grading labs mentioned above.

If you acquire a diamond that has been graded by a tier two lab, you may possibly end up paying much more for a lesser high quality diamond. So for example, a diamond rated a “F” in coloration at a tier 2 lab could get a G, H, or lower shade rating at a more trustworthy lab.

The sector also discounts diamonds graded by lesser identified labs by about fifteen-thirty% or more. So both you only purchase a diamond graded by a tier one lab or you accept that you may well be getting a lesser high quality diamond than what is said on the report if that diamond is graded by a lesser identified lab.

two. A lot of huge chain stores have massive contracts with lesser acknowledged labs with “softer” diamond grading tips. Some of these softer labs set “recommended alternative values” on the lab reviews – values which are higher than what shops intends sell the diamonds for.

So a salesperson in a chain shop could say to you, “Look at the excellent offer you are acquiring right here. We are promoting you this diamond engagement ring for $2500 but the report states that the suggested substitute benefit is $4000.” Wow – what a deal – NOT! This is why it is greater that you believe in only unbiased tier 1 labs.

Also bear in mind that reliable diamond grading studies are not appraisals and do not provide appraisal figures. Diamond appraisals are usually grossly inflated and are not some thing you are going to want to depend on.

three. Diamond stories are riddled with disclaimers that specify that nothing at all is “accredited” or certain and that the labs are not accountable for mistakes. In simple fact, the GIA offers a disclaimer of kinds on their web site relating to the use of the word “certify.” The site states:

“It is incorrect to state that pupils, graduates, their businesses, or specific gemstones are “certified” by GIA. The Gemological Institute of The united states does not certify any individual or anything at all. Neither a student nor a graduate who has been awarded a certification or diploma, nor a gem which has been graded or identified by GIA has been qualified by GIA”.

So it is achievable that you the consumer is remaining keeping the bag must an inaccuracy in a report is later on discovered. Courts have often dominated that sellers, not labs, are liable for these kinds of problems. Why? Since the labs indicated beforehand that their studies could not be held liable.

Thankfully, there are a few approaches to give your self far more buyer protection:

A. You could fly to India in which jewelers supply a life span buyback policy to their clients. Way too expensive to fly?

B. You could discover 1 of the twenty% of US jewelers who promote entirely bonded diamonds. These are diamonds that are marketed with lifetime breakage, life span trade-in and life time buyback insurance policies.

C. Not as very good a cure as getting a completely bonded diamond but you could acquire a diamond that comes with an genuine “certificate” and not a report. “Licensed diamonds do come with guaranties” albeit for shorter durations.


Some sellers refer to a “diamond report” as a “accredited diamond” but technically this is not appropriate. From a legal standpoint, a diamond report is a basically an professional opinion however in actuality, elements of a diamond grading report are not just opinions.

For example, a diamond’s carat (fat) can be accurately determined as properly as its minimize grade by measuring its optical performance or by referring to a pc product. A certification on the other hand is a statement of reality – a document for which the issuer accepts lawful responsibility and will make restitution to the client for blunders.

Some best diamond grading labs provide both studies and certificates. AGS provides Diamond Good quality Files (non-qualified studies) and also Diamond High quality Certificates. Diamond Quality Certificates are prepared exclusively for AGS retail jewelers and offers guaranties from taking part American Gem Culture member merchants.

GCAL certifies it’s diamond grading also. Its 100% funds-back again promise policy is valid for a period of time of two years from the date on the relevant certificate. This plan guarantees the accuracy of the lower, coloration and clarity grades and the carat bodyweight.

A report or certification should will have a variety on it that might or may possibly not be inscribed on a diamond. You will be able to enter that amount on the website of the certifying lab to examine a report’s validity.

Elements Of A Diamond Grading Report

Diamond grading reviews are often evolving but particular element need to continue being the identical. For occasion, the:

The Report #. This amount is presented and recorded in a lab’s record and might or might not be inscribed on a diamond’s girdle.

Carat Bodyweight: The bodyweight of a diamond is measured to the hundredth of a carat and some even supply this sort of evaluate to the thousandth of a carat (one.123ct.). Carat is the most objective and the best to recognize of the 4Cs simply because all one particular has to do is bodyweight the stone.

Coloration Quality: This tells you the level of color absence in the diamond. The considerably less colour the greater the grade.

Diamonds are usually graded from D-Z the nearer to “D” the whiter the diamond. You must by no means see diamond coloration variety this kind of as (G-H, I-J-K, and so on) on a diamond report. You should only see color ranges on appraisals for stones that are mounted.
