Read The Diamond Grading Report Prior to Acquiring An Engagement Ring

Not all sellers give diamond grading lab reports (aka diamond high quality studies) to their shoppers. So my common suggestions to you is to maintain your cash in your pocket when dealing with this kind of jewelers.

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

A lab report is an unbiased evaluation of the 4Cs of a loose diamond and includes a plotted diagram of the stone’s clarity traits and a graphic representation of the stone’s proportions. Having such a report allows you to assess diamonds of different qualities and in the long run helps you make a much more knowledgeable acquiring decision 鑽石戒指推薦.

A retailer may cut corners and not supply a lab report or an unscrupulous vendor might give a fake one due to the fact of the time, trouble and price he’ll bear to acquiring a stone graded.

Yeah – there is a cost for grading a diamond (though that cost is at some point paid out by the customer), additionally the transport and insurance policies fees for sending the diamond to the lab. And permit us not fail to remember the prospect price of a jeweler not having the diamond in his store for sale for a number of weeks although the grading takes area.

However, a diamond grading report may also not be available simply because the fees to receiving one particular could impact too seriously on the last price of the ring.

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

As you research for that best diamond engagement ring for your sweetheart, you’ll uncover that there is an alphabet soup of labs claiming to provide respected diamond grading reviews. But I would only set my cash on…

The Leading Diamond Grading Lab Reviews

Sure, all diamond top quality stories 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 offers highly regarded reports or “diamond certificates” as they are referred to by GCAL.

The GIA has the strongest global popularity for independence and consistency. Thanks to their constant coloration and clarity strictness recommendations, the globe’s largest and most expensive diamonds have been sent there for grading decades. In 2006, GIA-GTL additional a two-dimensional reduce grading program for round brilliant diamonds.

AGS employs the strictest lower standards in the industry. It employs a a few-dimensional mild overall performance metric that can quality a number of diamond shapes. In truth, it is the only cut grading method that is recognized by the scientific group.

What is far more, its Diamond Good quality Document makes use of a exclusive and proprietary to ten grading system to assess the 4 Cs – a method which is simpler to understand than GIA’s grading system. In simple fact, AGS even goes the further step by equating their -ten rating scale to other types of ranking.

For illustration, the typical VS1 diamond clarity ranking is a three on the AGS Diamond Top quality Doc.

Diamond Reporting – The Negatives

one. Diamond grading is not standardized or controlled and that’s why you may possibly come across tier two labs that employ looser guidelines to the tier one grading labs talked about earlier mentioned.

If you get a diamond that has been graded by a tier 2 lab, you may possibly finish up spending far more for a lesser quality diamond. So for example, a diamond rated a “F” in color at a tier two lab might get a G, H, or lower shade ranking at a much more reliable lab.

The business also discounts diamonds graded by lesser acknowledged labs by about 15-30% or more . So possibly you only get a diamond graded by a tier one lab or you acknowledge that you may be acquiring a lesser top quality diamond than what is mentioned on the report if that diamond is graded by a lesser known lab.

two. Numerous huge chain stores have huge contracts with lesser known labs with “softer” diamond grading recommendations. Some of these softer labs place “recommended replacement values” on the lab stories – values which are higher than what merchants intends sell the diamonds for.

So a salesperson in a chain shop may possibly say to you, “Appear at the fantastic deal you are getting right here. We are marketing you this diamond engagement ring for $2500 but the report claims that the proposed replacement value is $4000.” Wow – what a deal – NOT! This is why it is much better that you have faith in only unbiased tier one labs.

Also bear in thoughts that reliable diamond grading studies are not appraisals and do not supply appraisal figures. Diamond appraisals are usually grossly inflated and are not something you will want to depend on.

3. Diamond reports are riddled with disclaimers that specify that nothing is “certified” or assured and that the labs are not accountable for problems. In reality, the GIA provides a disclaimer of sorts on their web site with regards to the use of the word “certify.” The website claims:

“It is incorrect to state that students, graduates, their companies, or distinct gemstones are “accredited” by GIA. The Gemological Institute of The us does not certify anybody or anything at all. Neither a scholar nor a graduate who has been awarded a certificate or diploma, nor a gem which has been graded or determined by GIA has been qualified by GIA”.

So it is feasible that you the buyer is left keeping the bag must an inaccuracy in a report is later found. Courts have often dominated that sellers, not labs, are accountable for such errors. Why? Due to the fact the labs indicated beforehand that their reports couldn’t be held liable.

Luckily, there are a pair ways to give yourself a lot more customer defense:

A. You could fly to India exactly where jewelers offer you a life span buyback coverage to their buyers. As well costly to fly?

B. You could locate 1 of the 20% of US jewelers who market entirely bonded diamonds. These are diamonds that are marketed with life span breakage, lifetime trade-in and life span buyback guidelines.

C. Not as good a remedy as acquiring a totally bonded diamond but you could acquire a diamond that comes with an true “certification” 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 lawful standpoint, a diamond report is a just an skilled viewpoint however in actuality, aspects of a diamond grading report are not just opinions.

For illustration, a diamond’s carat (excess weight) can be precisely identified as well as its lower quality by measuring its optical efficiency or by referring to a personal computer product. A certification on the other hand is a statement of simple fact – a document for which the issuer accepts legal responsibility and will make restitution to the customer for errors.

Some top diamond grading labs offer equally reviews and certificates. AGS delivers Diamond High quality Files (non-licensed studies) and also Diamond Quality Certificates. Diamond Good quality Certificates are ready completely for AGS retail jewelers and provides guaranties from collaborating American Gem Society member shops.

GCAL certifies it really is diamond grading also. Its a hundred% cash-again ensure policy is valid for a interval of two several years from the date on the relevant certificate. This policy makes certain the precision of the cut, shade and clarity grades and the carat bodyweight.

A report or certification ought to will have a amount on it that might or may not be inscribed on a diamond. You will be capable to enter that quantity on the site of the certifying lab to check out a report’s validity.
