Read The Diamond Grading Report Ahead of Buying An Engagement Ring

Not all sellers supply diamond grading lab stories (aka diamond top quality reviews) to their buyers. So my basic guidance to you is to keep your cash in your pocket when working with this kind of jewelers.

Only buy a diamond engagement ring if it comes with the original diamond top quality report.

A lab report is an impartial evaluation of the 4Cs of a unfastened diamond and includes a plotted diagram of the stone’s clarity traits and a graphic representation of the stone’s proportions. Obtaining this sort of a report allows you to compare diamonds of diverse characteristics and in the end aids you make a a lot more informed purchasing choice gia 鑽石.

A retailer may lower corners and not supply a lab report or an unscrupulous vendor could provide a faux a single due to the fact of the time, trouble and expense he’ll bear to obtaining a stone graded.

Yeah – there is a cost for grading a diamond (even though that expense is at some point paid by the buyer), in addition the delivery and insurance coverage costs for sending the diamond to the lab. And let us not neglect the prospect price of a jeweler not obtaining the diamond in his retailer for sale for a couple of months although the grading requires spot.

Nonetheless, a diamond grading report could also not be available since the fees to receiving 1 may possibly impact as well heavily on the closing price tag of the ring.

For illustration, a .3ct diamond ring costing $250 say, might expense close to $75 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 may locate that there is an alphabet soup of labs claiming to provide respected diamond grading reports. But I would only place my cash on…

The Premier Diamond Grading Lab Studies

Of course, all diamond top quality studies are not created equivalent. Inside of the market, 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 Society Laboratories).

The GCAL (Gem Certification and Assurance Lab) also delivers highly regarded reviews or “diamond certificates” as they are referred to by GCAL.

The GIA has the strongest global reputation for independence and consistency. Thanks to their consistent coloration and clarity strictness tips, the globe’s greatest and most costly diamonds have been sent there for grading a long time. In 2006, GIA-GTL added a two-dimensional minimize grading technique for round excellent diamonds.

AGS uses the strictest minimize standards in the business. It employs a a few-dimensional mild efficiency metric that can grade a number of diamond shapes. In simple fact, it is the only lower grading program that is regarded by the scientific group.

What is a lot more, its Diamond Good quality Doc makes use of a exclusive and proprietary to ten grading technique to consider the 4 Cs – a technique which is less complicated to comprehend than GIA’s grading system. In truth, AGS even goes the added step by equating their -ten score scale to other kinds of rating.

For instance, the conventional VS1 diamond clarity score is a 3 on the AGS Diamond Quality Document.

Diamond Reporting – The Disadvantages

1. Diamond grading is not standardized or regulated and therefore you might occur throughout tier 2 labs that employ looser recommendations to the tier 1 grading labs described over.

If you acquire a diamond that has been graded by a tier 2 lab, you could end up paying more for a lesser quality diamond. So for example, a diamond rated a “F” in coloration at a tier 2 lab might get a G, H, or reduced coloration rating at a far more reputable lab.

The market also discount rates diamonds graded by lesser acknowledged labs by about fifteen-thirty% or more. So either you only get a diamond graded by a tier 1 lab or you accept that you might be getting a lesser quality diamond than what is mentioned on the report if that diamond is graded by a lesser acknowledged lab.

2. A lot of big chain retailers have huge contracts with lesser identified labs with “softer” diamond grading guidelines. Some of these softer labs set “proposed substitution values” on the lab stories – values which are greater than what stores intends sell the diamonds for.

So a salesperson in a chain keep might say to you, “Seem at the fantastic offer you are receiving here. We are promoting you this diamond engagement ring for $2500 but the report claims that the recommended substitution price is $4000.” Wow – what a offer – NOT! This is why it is better that you believe in only unbiased tier one labs.

Also bear in brain that reputable diamond grading reports are not appraisals and never provide appraisal figures. Diamond appraisals are often grossly inflated and are not anything you will want to rely on.

three. Diamond studies are riddled with disclaimers that specify that absolutely nothing is “accredited” or guaranteed and that the labs are not accountable for problems. In reality, the GIA provides a disclaimer of types on their site relating to the use of the term “certify.” The web site suggests:

“It is incorrect to point out that students, graduates, their organizations, or distinct gemstones are “licensed” by GIA. The Gemological Institute of The us does not certify anybody or anything at all. Neither a student nor a graduate who has been awarded a certificate or diploma, nor a gem which has been graded or recognized by GIA has been accredited by GIA”.

So it is attainable that you the customer is remaining holding the bag must an inaccuracy in a report is later on discovered. Courts have frequently dominated that sellers, not labs, are dependable for this kind of mistakes. Why? Since the labs indicated beforehand that their stories could not be held liable.

Fortunately, there are a couple approaches to give your self more consumer defense:

A. You could fly to India exactly where jewelers supply a life time buyback policy to their buyers. Way too pricey to fly?

B. You could discover one of the 20% of US jewelers who offer entirely bonded diamonds. These are diamonds that are bought with life time breakage, life time trade-in and life span buyback procedures.

C. Not as great a remedy as buying a entirely bonded diamond but you could purchase a diamond that arrives with an genuine “certificate” and not a report. “Certified diamonds do appear with guaranties” albeit for shorter durations.


Some sellers refer to a “diamond report” as a “certified diamond” but technically this is not correct. From a legal standpoint, a diamond report is a basically an expert 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 well as its minimize grade by measuring its optical performance or by referring to a laptop design. A certification on the other hand is a statement of truth – a doc for which the issuer accepts legal responsibility and will make restitution to the consumer for problems.

Some prime diamond grading labs supply equally stories and certificates. AGS provides Diamond High quality Documents (non-certified reviews) and also Diamond Good quality Certificates. Diamond High quality Certificates are prepared exclusively for AGS retail jewelers and provides guaranties from taking part American Gem Modern society member merchants.

GCAL certifies it is diamond grading also. Its 100% cash-again ensure plan is legitimate for a interval of two a long time from the day on the applicable certificate. This policy makes certain the accuracy of the cut, color and clarity grades and the carat fat.

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

Aspects Of A Diamond Grading Report

Diamond grading stories are usually evolving but specified aspect ought to continue being the identical . For instance, the:

The Report #. This quantity is offered and recorded in a lab’s file and may or may not be inscribed on a diamond’s girdle. You can enter the report variety on a grading lab’s internet site to check out the authenticity of the diamond quality report or to get much more details about the diamond.

Carat Fat: The weight of a diamond is measured to the hundredth of a carat and some even offer this kind of measure to the thousandth of a carat (1.123ct.). Carat is the most goal and the easiest to understand of the 4Cs due to the fact all 1 has to do is excess weight the stone.

Coloration Grade: This tells you the level of color absence in the diamond. The considerably less colour the increased the quality.

Diamonds are generally graded from D-Z the closer to “D” the whiter the diamond. You ought to in no way see diamond colour selection this sort of as (G-H, I-J-K, and so on) on a diamond report. You ought to only see coloration ranges on appraisals for stones that are mounted.
