Study The Diamond Grading Report Just before Purchasing An Engagement Ring

Not all sellers provide diamond grading lab studies (aka diamond high quality stories) to their shoppers. So my general suggestions to you is to preserve your cash in your pocket when working with these kinds of jewelers.

Only buy a diamond engagement ring if it arrives with the authentic diamond top quality report.

A lab report is an impartial evaluation of the 4Cs of a unfastened diamond and consists of a plotted diagram of the stone’s clarity characteristics and a graphic representation of the stone’s proportions. Having this kind of a report permits you to assess diamonds of various traits and ultimately assists you make a a lot more knowledgeable acquiring determination 求婚戒指.

A retailer could minimize corners and not provide a lab report or an unscrupulous vendor may possibly provide a faux 1 because of the time, difficulties and cost he’ll bear to getting a stone graded.

Yeah – there is a price tag for grading a diamond (though that value is sooner or later paid out by the buyer), in addition the shipping and delivery and insurance policy costs for sending the diamond to the lab. And let us not overlook the chance cost of a jeweler not getting the diamond in his shop for sale for a number of weeks whilst the grading takes area.

Nevertheless, a diamond grading report could also not be offered simply because the charges to obtaining 1 might effect too greatly on the ultimate price tag of the ring.

For instance, a .3ct diamond ring costing $250 say, may possibly value close to $75 to be graded and have the report quantity inscribed on the girdle on the diamond.

As you search for that ideal diamond engagement ring for your sweetheart, you are going to discover that there is an alphabet soup of labs declaring to give trustworthy diamond grading reviews. But I would only put my funds on…

The Leading Diamond Grading Lab Stories

Of course, all diamond top quality studies are not produced equivalent. Inside of the business, 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 Modern society Laboratories).

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

The GIA has the strongest international popularity for independence and regularity. Due to their continual shade and clarity strictness guidelines, the globe’s biggest and most costly diamonds have been sent there for grading many years. In 2006, GIA-GTL extra a two-dimensional reduce grading system for round amazing diamonds.

AGS employs the strictest lower specifications in the sector. It utilizes a three-dimensional light-weight overall performance metric that can grade several diamond designs. In fact, it is the only minimize grading program that is identified by the scientific group.

What is far more, its Diamond High quality Document uses a special and proprietary to ten grading system to consider the four Cs – a system which is less difficult to comprehend than GIA’s grading program. In truth, AGS even goes the added phase by equating their -10 score scale to other varieties of ranking.

For illustration, the standard VS1 diamond clarity score is a 3 on the AGS Diamond Top quality Doc.

Diamond Reporting – The Downsides

1. Diamond grading is not standardized or regulated and therefore you could occur throughout tier 2 labs that use looser recommendations to the tier one grading labs mentioned earlier mentioned.

If you acquire a diamond that has been graded by a tier 2 lab, you could end up paying out much more for a lesser good quality diamond. So for case in point, a diamond rated a “F” in color at a tier two lab may get a G, H, or decrease color rating at a far more reliable lab.

The business also reductions diamonds graded by lesser known labs by about 15-30% or far more . So both you only get a diamond graded by a tier one lab or you acknowledge that you may be purchasing a lesser top quality diamond than what is stated on the report if that diamond is graded by a lesser recognized lab.

2. Numerous massive chain retailers have massive contracts with lesser identified labs with “softer” diamond grading suggestions. Some of these softer labs place “recommended substitute values” on the lab stories – values which are higher than what stores intends market the diamonds for.

So a salesperson in a chain store could say to you, “Look at the fantastic offer you are receiving right here. We are marketing you this diamond engagement ring for $2500 but the report says that the proposed replacement value is $4000.” Wow – what a offer – NOT! This is why it is far better that you believe in only unbiased tier one labs.

Also bear in head that reliable diamond grading reports are not appraisals and will not offer appraisal figures. Diamond appraisals are usually grossly inflated and are not one thing you may want to count on.

three. Diamond reports are riddled with disclaimers that specify that nothing at all is “accredited” or guaranteed and that the labs are not accountable for errors. In fact, the GIA provides a disclaimer of sorts on their web site relating to the use of the word “certify.” The website says:

“It is incorrect to point out that students, graduates, their businesses, or specific gemstones are “accredited” by GIA. The Gemological Institute of The us does not certify anyone or everything. Neither a pupil nor a graduate who has been awarded a certificate or diploma, nor a gem which has been graded or discovered by GIA has been accredited by GIA”.

So it is achievable that you the client is still left keeping the bag need to an inaccuracy in a report is later discovered. Courts have frequently ruled that sellers, not labs, are dependable for this sort of problems. Why? Due to the fact the labs indicated beforehand that their studies could not be held liable.

Fortunately, there are a few methods to give your self a lot more consumer safety:

A. You could fly to India the place jewelers supply a life time buyback policy to their customers. As well pricey to fly?

B. You could uncover a single of the 20% of US jewelers who promote fully bonded diamonds. These are diamonds that are bought with lifetime breakage, life span trade-in and life time buyback insurance policies.

C. Not as excellent a remedy as purchasing a entirely bonded diamond but you could get a diamond that will come with an actual “certification” and not a report. “Certified diamonds do come with guaranties” albeit for shorter durations.


Some sellers refer to a “diamond report” as a “qualified diamond” but technically this is not proper. From a authorized standpoint, a diamond report is a basically an skilled impression though in actuality, factors of a diamond grading report are not just viewpoints.

For illustration, a diamond’s carat (excess weight) can be correctly established as properly as its reduce grade by measuring its optical efficiency or by referring to a pc product. A certification on the other hand is a statement of simple fact – a doc for which the issuer accepts authorized responsibility and will make restitution to the client for mistakes.

Some top diamond grading labs supply the two stories and certificates. AGS offers Diamond Top quality Paperwork (non-certified studies) and also Diamond Top quality Certificates. Diamond Top quality Certificates are prepared exclusively for AGS retail jewelers and gives guaranties from participating American Gem Modern society member retailers.

GCAL certifies it truly is diamond grading also. Its a hundred% cash-again ensure policy is legitimate for a interval of two a long time from the date on the relevant certificate. This coverage assures the accuracy of the lower, shade and clarity grades and the carat excess weight.

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

Factors Of A Diamond Grading Report
