Read through The Diamond Grading Report Just before Acquiring An Engagement Ring

Not all sellers offer diamond grading lab studies (aka diamond top quality stories) to their shoppers. So my basic guidance to you is to hold your cash in your pocket when working with these kinds of jewelers.

Only buy a diamond engagement ring if it comes with the unique diamond high quality report.

A lab report is an impartial analysis of the 4Cs of a loose diamond and contains a plotted diagram of the stone’s clarity characteristics and a graphic representation of the stone’s proportions. Possessing such a report makes it possible for you to compare diamonds of distinct attributes and eventually assists you make a a lot more educated purchasing determination 結婚戒指.

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

Yeah – there is a cost for grading a diamond (though that price is at some point paid by the customer), plus the delivery and insurance charges for sending the diamond to the lab. And enable us not neglect the prospect value of a jeweler not having the diamond in his retailer for sale for a couple of weeks whilst the grading takes place.

However, a diamond grading report may possibly also not be offered simply because the charges to getting one could impact way too heavily on the ultimate value of the ring.

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

As you search for that ideal diamond engagement ring for your sweetheart, you may discover that there is an alphabet soup of labs professing to provide reliable diamond grading studies. But I would only set my cash on…

The Leading Diamond Grading Lab Reviews

Indeed, all diamond high quality studies are not developed equal. Inside 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 gives very regarded stories or “diamond certificates” as they are referred to by GCAL.

The GIA has the strongest global popularity for independence and regularity. Owing to their constant colour and clarity strictness suggestions, the globe’s greatest and most pricey diamonds have been sent there for grading a long time. In 2006, GIA-GTL added a two-dimensional cut grading technique for round excellent diamonds.

AGS employs the strictest lower standards in the business. It employs a 3-dimensional mild efficiency metric that can quality numerous diamond styles. In simple fact, it is the only minimize grading method that is regarded by the scientific community.

What is more, its Diamond Good quality Doc makes use of a special and proprietary to ten grading technique to consider the 4 Cs – a technique which is easier to comprehend than GIA’s grading technique. In reality, AGS even goes the extra step by equating their -ten score scale to other forms of ranking.

For case in point, the typical VS1 diamond clarity ranking is a three on the AGS Diamond Quality Doc .

Diamond Reporting – The Disadvantages

one. Diamond grading is not standardized or regulated and that’s why you may possibly occur throughout tier 2 labs that make use of looser recommendations to the tier 1 grading labs talked about above.

If you buy a diamond that has been graded by a tier 2 lab, you may end up spending far more for a lesser quality diamond. So for case in point, a diamond rated a “F” in colour at a tier two lab may get a G, H, or reduce coloration ranking at a much more respected lab.

The sector also discount rates diamonds graded by lesser recognized labs by about fifteen-30% or a lot more. So both you only buy a diamond graded by a tier 1 lab or you acknowledge that you might be buying a lesser top quality diamond than what is said on the report if that diamond is graded by a lesser recognized lab.

two. Numerous massive chain stores have large contracts with lesser recognized labs with “softer” diamond grading recommendations. Some of these softer labs put “proposed alternative values” on the lab reviews – values which are increased than what retailers intends promote the diamonds for.

So a salesperson in a chain retailer may say to you, “Look at the excellent offer you are obtaining here. We are marketing you this diamond engagement ring for $2500 but the report states that the proposed replacement price is $4000.” Wow – what a deal – NOT! This is why it is much better that you trust only impartial tier 1 labs.

Also bear in head that reliable diamond grading stories are not appraisals and don’t offer you appraisal figures. Diamond appraisals are usually grossly inflated and are not some thing you may want to count on.

3. Diamond reports are riddled with disclaimers that specify that nothing at all is “qualified” or confirmed and that the labs are not accountable for errors. In fact, the GIA gives a disclaimer of kinds on their website concerning the use of the word “certify.” The website says:

“It is incorrect to condition that students, graduates, their organizations, or specific gemstones are “accredited” by GIA. The Gemological Institute of The united states does not certify any individual or something. Neither a pupil nor a graduate who has been awarded a certificate or diploma, nor a gem which has been graded or identified by GIA has been licensed by GIA”.

So it is achievable that you the buyer is remaining keeping the bag need to an inaccuracy in a report is afterwards uncovered. Courts have frequently dominated that sellers, not labs, are accountable for this kind of mistakes. Why? Since the labs indicated beforehand that their reports couldn’t be held liable.

Fortunately, there are a few approaches to give yourself far more customer defense:

A. You could fly to India the place jewelers offer a lifetime buyback policy to their clients. Way too costly to fly?

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

C. Not as great a cure as buying a entirely bonded diamond but you could purchase a diamond that comes with an true “certificate” and not a report. “Certified diamonds do occur 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 lawful standpoint, a diamond report is a just an specialist view even though in actuality, aspects of a diamond grading report are not just thoughts.

For illustration, a diamond’s carat (bodyweight) can be accurately determined as nicely as its reduce grade by measuring its optical performance or by referring to a computer model. A certificate 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 blunders.

Some prime diamond grading labs provide each studies and certificates. AGS offers Diamond Top quality Paperwork (non-certified reports) and also Diamond High quality Certificates. Diamond Top quality Certificates are prepared completely for AGS retail jewelers and offers guaranties from collaborating American Gem Modern society member shops.

GCAL certifies it’s diamond grading also. Its one hundred% cash-back ensure coverage is valid for a time period of two years from the date on the applicable certification. This coverage assures the accuracy of the lower, color and clarity grades and the carat bodyweight.

A report or certificate should will have a number on it that may or may not be inscribed on a diamond. You will be able to enter that quantity on the website of the certifying lab to examine a report’s validity.

Aspects Of A Diamond Grading Report

Diamond grading studies are often evolving but specified factor must stay the exact same. For instance, the:

The Report #. This number is presented and recorded in a lab’s report and may possibly or could 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 provide such evaluate to the thousandth of a carat (one.123ct.). Carat is the most aim and the easiest to comprehend of the 4Cs due to the fact all one has to do is excess weight the stone.

Shade Quality: This tells you the level of coloration absence in the diamond. The significantly less colour the higher the grade.

Diamonds are generally graded from D-Z the nearer to “D” the whiter the diamond. You should in no way see diamond color range such as (G-H, I-J-K, and so on) on a diamond report. You ought to only see shade ranges on appraisals for stones that are mounted.

Clarity Quality: Virtually every diamond has inner imperfections referred to as inclusions and exterior imperfections referred to as blemishes. A diamond is graded according to the dimension, type, location and sum of these flaws.
