Study The Diamond Grading Report Just before Getting An Engagement Ring


Not all sellers give diamond grading lab reports (aka diamond top quality stories) to their customers. So my common suggestions to you is to preserve your funds in your pocket when working with these kinds of jewelers.

Only obtain a diamond engagement ring if it comes with the first diamond high quality report.

A lab report is an unbiased analysis of the 4Cs of a unfastened diamond and contains a plotted diagram of the stone’s clarity characteristics and a graphic representation of the stone’s proportions. Obtaining these kinds of a report allows you to examine diamonds of distinct characteristics and in the long run aids you make a more informed buying selection.

A retailer could lower corners and not give a lab report or an unscrupulous vendor could provide a phony 1 due to the fact of the time, difficulty and price he’ll bear to receiving a stone graded.

Yeah – there is a price tag for grading a diamond (even though that price is at some point compensated by the client), furthermore the transport and insurance fees for sending the diamond to the lab. And allow us not overlook the chance cost of a jeweler not obtaining the diamond in his shop for sale for a number of weeks while the grading takes place.

Nonetheless, a diamond grading report may possibly also not be accessible since the expenses to acquiring one may possibly impact way too heavily on the ultimate price tag of the ring.

For case in point, a .3ct diamond ring costing $250 say, may value around $75 to be graded and have the report number inscribed on the girdle on the diamond.

As you lookup for that excellent diamond engagement ring for your sweetheart, you’ll find that there is an alphabet soup of labs declaring to supply trustworthy diamond grading reviews. But I would only place my funds on…

The Premier Diamond Grading Lab Stories

Sure, all diamond good quality studies are not created equal. In the industry, 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 Society Laboratories).

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

The GIA has the strongest international status for independence and consistency. Due to their constant colour and clarity strictness recommendations, the globe’s biggest and most pricey diamonds have been sent there for grading many years. In 2006, GIA-GTL added a two-dimensional minimize grading program for spherical brilliant diamonds.

AGS employs the strictest minimize expectations in the industry. It utilizes a a few-dimensional light-weight functionality metric that can grade numerous diamond styles. In fact, it is the only reduce grading technique that is acknowledged by the scientific neighborhood.

What is far more, its Diamond Quality Document makes use of a unique and proprietary to ten grading technique to evaluate the four Cs – a technique which is less difficult to understand than GIA’s grading program. In reality, AGS even goes the added action by equating their -ten rating scale to other forms of ranking.

For example, the conventional VS1 diamond clarity ranking is a 3 on the AGS Diamond High quality Document.

Diamond Reporting – The Negatives

one. Diamond grading is not standardized or regulated and hence you may possibly appear throughout tier 2 labs that employ looser guidelines to the tier one grading labs pointed out above.

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

The market also discounts diamonds graded by lesser acknowledged labs by about fifteen-30% or more. So either you only purchase a diamond graded by a tier one lab or you take that you might be buying a lesser quality diamond than what is stated on the report if that diamond is graded by a lesser known lab.

two. Many massive chain retailers have large contracts with lesser known labs with “softer” diamond grading recommendations. Some of these softer labs put “advised substitution values” on the lab stories – values which are greater than what shops intends sell the diamonds for.

So a salesperson in a chain retailer could say to you, “Appear at the fantastic deal you are obtaining listed here. We are promoting you this diamond engagement ring for $2500 but the report says that the proposed replacement worth is $4000.” Wow – what a offer – NOT! This is why it is much better that you have confidence in only unbiased tier 1 labs.

Also bear in mind that respected diamond grading studies are not appraisals and will not offer appraisal figures. Diamond appraisals are frequently grossly inflated and are not anything you’ll want to depend on.

3. Diamond reviews are riddled with disclaimers that specify that nothing at all is “certified” or certain and that the labs are not accountable for errors. In truth, the GIA delivers a disclaimer of kinds on their site relating to the use of the term “certify.” The internet site claims:

“It is incorrect to point out that learners, graduates, their firms, or particular gemstones are “licensed” by GIA. The Gemological Institute of America does not certify any individual 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 identified by GIA has been licensed by GIA”.

So it is attainable that you the buyer is remaining keeping the bag need to an inaccuracy in a report is later on uncovered. Courts have usually dominated that sellers, not labs, are liable for such mistakes. Why? Since the labs indicated beforehand that their studies couldn’t be held liable.

The good news is, there are a few approaches to give your self a lot more customer security:

A. You could fly to India in which jewelers supply a life span buyback plan to their customers. Also high-priced to fly?

B. You could discover one of the twenty% of US jewelers who offer fully bonded diamonds. These are diamonds that are offered with lifetime breakage, life time trade-in and life time buyback guidelines.

C. Not as excellent a cure as purchasing a totally bonded diamond but you could get a diamond that comes with an true “certification” and not a report. “Accredited 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 opinion although in actuality, factors of a diamond grading report are not just thoughts.

For case in point, a diamond’s carat (bodyweight) can be accurately identified as nicely as its lower grade by measuring its optical effectiveness or by referring to a computer model. A certification on the other hand is a statement of truth – a doc for which the issuer accepts authorized duty and will make restitution to the client for mistakes.

Some best diamond grading labs offer you both studies and certificates. AGS gives Diamond Good quality Documents (non-licensed studies) and also Diamond Top quality Certificates. Diamond Quality Certificates are geared up exclusively for AGS retail jewelers and delivers guaranties from taking part American Gem Society member shops.

GCAL certifies it really is diamond grading also. Its one hundred% income-back promise policy is legitimate for a period of two many years from the day on the relevant certificate. This policy guarantees the precision of the minimize, coloration and clarity grades and the carat bodyweight.

A report or certification must will have a number on it that could or might not be inscribed on a diamond. You will be able to enter that number on the internet site of the certifying lab to check out a report’s validity.

Elements Of A Diamond Grading Report

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

The Report #. This number is given and recorded in a lab’s file and could or may not be inscribed on a diamond’s girdle. You can enter the report variety on a grading lab’s site to verify the authenticity of the diamond good quality report or to get more information about the diamond.

Carat Weight: The weight of a diamond is calculated to the hundredth of a carat and some even supply such evaluate to the thousandth of a carat (1.123ct.). Carat is the most goal and the simplest to realize of the 4Cs because all a single has to do is bodyweight the stone.

Colour Grade: This tells you the degree of shade absence in the diamond. The significantly less colour the increased the grade.

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

Clarity Quality: Almost every single diamond has inside imperfections known as inclusions and exterior imperfections known as blemishes. A diamond is graded according to the dimension, sort, area and amount of these flaws.

Clarity grades assortment from Flawless (FL) – Incorporated. Labs use a couple authorities to grade the clarity of a diamond in buy to come up with a much more accurate reading.
