Read The Diamond Grading Report Before Getting An Engagement Ring

Not all sellers supply diamond grading lab stories (aka diamond quality reviews) to their shoppers. So my standard guidance to you is to hold your income in your pocket when dealing with this kind of jewelers.

Only purchase a diamond engagement ring if it arrives with the unique diamond good quality report.

A lab report is an impartial analysis of the 4Cs of a unfastened diamond and involves a plotted diagram of the stone’s clarity traits and a graphic representation of the stone’s proportions. Having this sort of a report makes it possible for you to compare diamonds of diverse characteristics and in the end will help you make a more informed getting decision.

A retailer may possibly cut corners and not provide a lab report or an unscrupulous seller may possibly supply a phony a single because of the time, difficulty and cost he’ll bear to obtaining a stone graded.

Yeah – there is a cost for grading a diamond (though that expense is sooner or later paid by the consumer), furthermore the shipping and insurance expenses for sending the diamond to the lab. And let us not fail to remember the chance value of a jeweler not obtaining the diamond in his shop for sale for a handful of months even though the grading normally takes location.

However, a diamond grading report might also not be obtainable since the fees to acquiring one particular may possibly influence way too greatly on the last price of the ring.

For illustration, a .3ct diamond ring costing $250 say, may value around $seventy five to be graded and have the report quantity inscribed on the girdle on the diamond.

As you lookup for that excellent diamond engagement ring for your sweetheart, you will find that there is an alphabet soup of labs proclaiming to offer reliable diamond grading reports. But I would only set my income on…

The Leading Diamond Grading Lab Reviews

Indeed, all diamond high quality studies are not designed equal. In the sector, 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 offers extremely regarded studies or “diamond certificates” as they are referred to by GCAL.

The GIA has the strongest world-wide popularity for independence and regularity. Thanks to their constant colour and clarity strictness suggestions, the globe’s biggest and most high-priced diamonds have been sent there for grading many years. In 2006, GIA-GTL added a two-dimensional minimize grading program for spherical outstanding diamonds.

AGS utilizes the strictest cut standards in the industry. It employs a a few-dimensional gentle functionality metric that can quality a number of diamond designs. In reality, it is the only cut grading method that is recognized by the scientific group.

What is more, its Diamond Good quality Document utilizes a unique and proprietary to ten grading program to consider the four Cs – a system which is less difficult to understand than GIA’s grading program. In reality, AGS even goes the further step by equating their -10 ranking scale to other types of ranking.

For instance, the standard VS1 diamond clarity ranking is a three on the AGS Diamond High quality Doc.

Diamond Reporting – The Downsides

one. Diamond grading is not standardized or controlled and hence you may come throughout tier 2 labs that use looser recommendations to the tier 1 grading labs mentioned over.

If you acquire a diamond that has been graded by a tier 2 lab, you might stop up paying out far more for a lesser quality diamond. So for case in point, a diamond rated a “F” in colour at a tier 2 lab may possibly get a G, H, or reduced shade ranking at a more reliable lab.

The sector also reductions diamonds graded by lesser recognized labs by about 15-thirty% or far more. So possibly you only buy a diamond graded by a tier 1 lab or you settle for that you may well be getting a lesser high quality diamond than what is mentioned on the report if that diamond is graded by a lesser known lab.

two. A lot of big chain stores have large contracts with lesser acknowledged labs with “softer” diamond grading tips. Some of these softer labs put “proposed alternative values” on the lab stories – values which are higher than what retailers intends promote the diamonds for.

So a salesperson in a chain store could say to you, “Search at the great deal you are receiving here. We are offering you this diamond engagement ring for $2500 but the report states that the suggested substitute price is $4000.” Wow – what a offer – NOT! This is why it is far better that you trust only unbiased tier 1 labs.

Also bear in thoughts that reputable diamond grading stories are not appraisals and don’t supply appraisal figures. Diamond appraisals are often grossly inflated and are not anything you will want to count on.

three. Diamond reviews are riddled with disclaimers that specify that nothing at all is “accredited” or assured and that the labs are not accountable for glitches. In reality, the GIA offers a disclaimer of types on their internet site regarding the use of the term “certify.” The internet site states:

“It is incorrect to condition that college students, graduates, their firms, or distinct gemstones are “qualified” by GIA. The Gemological Institute of The usa does not certify anyone or something. Neither a pupil 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 possible that you the consumer is still left keeping the bag must an inaccuracy in a report is afterwards discovered. Courts have frequently dominated that sellers, not labs, are dependable for this kind of mistakes. Why? Due to the fact the labs indicated beforehand that their stories couldn’t be held liable.

Fortunately, there are a couple techniques to give your self more consumer protection:

A. You could fly to India where jewelers supply a life span buyback policy to their consumers. Way too high-priced to fly?

B. You could find one particular of the 20% of US jewelers who offer completely bonded diamonds. These are diamonds that are sold with life span breakage, life span trade-in and life time buyback policies.

C. Not as excellent a solution as purchasing a totally bonded diamond but you could acquire a diamond that arrives with an true “certificate” and not a report. “Licensed diamonds do occur with guaranties” albeit for shorter durations.


Some sellers refer to a “diamond report” as a “licensed diamond” but technically this is not proper. From a legal standpoint, a diamond report is a simply an specialist opinion even though in actuality, aspects of a diamond grading report are not just thoughts.

For instance, a diamond’s carat (weight) can be accurately identified as properly as its cut grade by measuring its optical effectiveness or by referring to a computer product. A certification on the other hand is a assertion of fact – a document for which the issuer accepts legal accountability and will make restitution to the buyer for blunders.

Some best diamond grading labs provide the two studies and certificates. AGS offers Diamond Top quality Paperwork (non-qualified studies) and also Diamond High quality Certificates. Diamond Good quality Certificates are ready solely for AGS retail jewelers and delivers guaranties from taking part American Gem Modern society member merchants.

GCAL certifies it is diamond grading also. Its 100% income-again ensure coverage is legitimate for a period of time of two many years from the day on the relevant certification. This policy assures the accuracy of the cut, coloration and clarity grades and the carat bodyweight.

A report or certificate must will have a quantity on it that may possibly or may possibly not be inscribed on a diamond. You will be able to enter that quantity on the internet site of the certifying lab to check a report’s validity.

Elements Of A Diamond Grading Report

Diamond grading studies are constantly evolving but specific aspect ought to stay the very same. For occasion, the:

The Report #. This amount is given and recorded in a lab’s report and may possibly or may not be inscribed on a diamond’s girdle. You can enter the report amount on a grading lab’s web site to examine the authenticity of the diamond quality report or to get much more information about the diamond.

Shade Quality: This tells you the amount of color absence in the diamond. The much less coloration the higher the grade.

Diamonds are generally graded from D-Z the closer to “D” the whiter the diamond. You ought to never ever see diamond color selection this kind of as (G-H, I-J-K, and so on) on a diamond report. You need to only see coloration ranges on appraisals for stones that are mounted.
