Read The Diamond Grading Report Before Purchasing An Engagement Ring

August 5, 2023 0 Comments

Not all sellers offer diamond grading lab reports (aka diamond top quality reports) to their consumers. So my basic guidance to you is to preserve your cash in your pocket when working with such jewelers.

Only acquire a diamond engagement ring if it will come with the unique diamond good quality report.

A lab report is an independent analysis of the 4Cs of a loose diamond and contains a plotted diagram of the stone’s clarity attributes and a graphic illustration of the stone’s proportions. Having such a report allows you to examine diamonds of diverse attributes and eventually aids you make a much more informed getting choice.

A retailer may lower corners and not provide a lab report or an unscrupulous vendor could provide a phony one since of the time, difficulties and expenditure he’ll bear to acquiring a stone graded.

Yeah – there is a value for grading a diamond (though that expense is sooner or later compensated by the consumer), plus the transport and insurance coverage costs for sending the diamond to the lab. And let us not forget the possibility value of a jeweler not obtaining the diamond in his shop for sale for a handful of weeks although the grading will take area.

However, a diamond grading report may also not be accessible since the fees to receiving a single may influence as well heavily on the final price tag of the ring.

For example, a .3ct diamond ring costing $250 say, could price all around $seventy five to be graded and have the report amount inscribed on the girdle on the diamond.

As you search for that excellent diamond engagement ring for your sweetheart, you will uncover that there is an alphabet soup of labs proclaiming to provide reliable diamond grading reviews. But I would only put my cash on…

The Premier Diamond Grading Lab Reviews

Yes, all diamond top quality reports are not produced equal. In 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 Modern society Laboratories).

The GCAL (Gem Certification and Assurance Lab) also gives very regarded studies or “diamond certificates” as they are referred to by GCAL.

The GIA has the strongest world-wide popularity for independence and regularity. Owing to their continual colour and clarity strictness suggestions, the globe’s greatest and most high-priced diamonds have been despatched there for grading many years. In 2006, GIA-GTL extra a two-dimensional lower grading system for spherical brilliant diamonds.

AGS employs the strictest cut requirements in the industry. It uses a three-dimensional mild efficiency metric that can grade a number of diamond designs. In fact, it is the only minimize grading method that is identified by the scientific local community.

What is much more, its Diamond Quality Document utilizes a special and proprietary to ten grading system to assess the 4 Cs – a program which is simpler to comprehend than GIA’s grading technique. In truth, AGS even goes the additional phase by equating their -10 rating scale to other types of rating.

For case in point, the conventional VS1 diamond clarity score is a three on the AGS Diamond High quality Document.

Diamond Reporting – The Negatives

1. Diamond grading is not standardized or regulated and hence you may possibly occur throughout tier two labs that employ looser tips to the tier one grading labs pointed out over.

If you acquire a diamond that has been graded by a tier 2 lab, you may stop up spending much more for a lesser top quality diamond. So for instance, a diamond rated a “F” in colour at a tier 2 lab could get a G, H, or decrease shade score at a more reputable lab.

The market also discount rates diamonds graded by lesser known labs by about fifteen-thirty% or far more. So possibly you only purchase a diamond graded by a tier 1 lab or you settle for that you may possibly be getting a lesser high quality diamond than what is said on the report if that diamond is graded by a lesser acknowledged lab.

2. A lot of massive chain merchants have huge contracts with lesser acknowledged labs with “softer” diamond grading suggestions. Some of these softer labs set “advised substitution values” on the lab studies – values which are increased than what merchants intends promote the diamonds for.

So a salesperson in a chain retailer might say to you, “Look at the wonderful deal you are obtaining here. We are promoting you this diamond engagement ring for $2500 but the report says that the suggested substitution benefit is $4000.” Wow – what a offer – NOT! This is why it is far better that you believe in only independent tier 1 labs.

Also bear in brain that trustworthy diamond grading reviews are not appraisals and will not supply appraisal figures. Diamond appraisals are often grossly inflated and are not anything you may want to count on.

three. Diamond studies are riddled with disclaimers that specify that nothing is “accredited” or guaranteed and that the labs are not accountable for glitches. In reality, the GIA provides a disclaimer of sorts on their website concerning the use of the term “certify.” The web site states:

“It is incorrect to point out that pupils, graduates, their firms, or specific gemstones are “qualified” by GIA. The Gemological Institute of The usa does not certify any individual or anything at all. Neither a pupil nor a graduate who has been awarded a certification 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 consumer is left holding the bag ought to an inaccuracy in a report is later on uncovered. Courts have regularly ruled that sellers, not labs, are liable for these kinds of mistakes. Why? Since the labs indicated beforehand that their stories could not be held liable.

Fortunately, there are a couple ways to give by yourself a lot more buyer safety:

A. You could fly to India in which jewelers supply a lifetime buyback coverage to their customers. Too costly to fly?

B. You could locate 1 of the twenty% of US jewelers who market completely bonded diamonds. 鑽石耳環推介 are diamonds that are marketed with life span breakage, lifetime trade-in and lifetime buyback guidelines.

C. Not as good a cure as getting a entirely bonded diamond but you could get a diamond that will come with an actual “certification” and not a report. “Accredited diamonds do appear 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 authorized standpoint, a diamond report is a simply an specialist opinion though in actuality, facets of a diamond grading report are not just thoughts.

For instance, a diamond’s carat (excess weight) can be properly determined as well as its lower grade by measuring its optical efficiency or by referring to a pc product. A certificate on the other hand is a statement of fact – a doc for which the issuer accepts authorized obligation and will make restitution to the customer for problems.

Some leading diamond grading labs provide both reports and certificates. AGS gives Diamond Quality Documents (non-certified stories) and also Diamond Good quality Certificates. Diamond High quality Certificates are geared up exclusively for AGS retail jewelers and provides guaranties from taking part American Gem Society member merchants.

GCAL certifies it really is diamond grading also. Its one hundred% funds-back again assure policy is valid for a interval of two years from the day on the applicable certificate. This policy guarantees the precision of the reduce, color and clarity grades and the carat bodyweight.

A report or certification ought to will have a number on it that might or may not be inscribed on a diamond. You will be ready to enter that variety on the internet site of the certifying lab to verify a report’s validity.

Components Of A Diamond Grading Report

Diamond grading studies are usually evolving but particular aspect should stay the exact same. For instance, the:

The Report #. This number is offered and recorded in a lab’s record and could or could not be inscribed on a diamond’s girdle. You can enter the report variety on a grading lab’s web site to check out the authenticity of the diamond good quality report or to get much more data about the diamond.

Color Grade: This tells you the degree of coloration absence in the diamond. The significantly less colour the higher the quality.
