Read The Diamond Grading Report Prior to Purchasing An Engagement Ring

Not all sellers give diamond grading lab reports (aka diamond top quality studies) to their consumers. So my standard tips to you is to hold your cash in your pocket when working with such jewelers.

Only purchase a diamond engagement ring if it comes with the authentic diamond top quality report.

A lab report is an impartial analysis of the 4Cs of a unfastened diamond and involves a plotted diagram of the stone’s clarity qualities and a graphic illustration of the stone’s proportions. Obtaining these kinds of a report enables you to compare diamonds of distinct attributes and in the end assists you make a more informed getting choice.

A retailer may possibly cut corners and not give a lab report or an unscrupulous seller could supply a phony 1 due to the fact of the time, trouble and cost he’ll bear to acquiring a stone graded.

Yeah – there is a price for grading a diamond (although that price is sooner or later compensated by the client), furthermore the shipping and delivery and insurance coverage fees for sending the diamond to the lab. And allow us not neglect the chance expense of a jeweler not obtaining the diamond in his keep for sale for a number of weeks whilst the grading requires location 鑽石 4c.

Nonetheless, a diamond grading report could also not be accessible simply because the costs to getting one particular might effect also seriously on the ultimate price of the ring.

For case in point, a .3ct diamond ring costing $250 say, might price close to $seventy five to be graded and have the report amount inscribed on the girdle on the diamond.

As you search for that perfect diamond engagement ring for your sweetheart, you are going to uncover that there is an alphabet soup of labs professing to supply respected diamond grading reviews. But I would only put my income on…

The Leading Diamond Grading Lab Reports

Yes, all diamond quality reviews are not designed equal. Inside of the market, 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 extremely regarded stories or “diamond certificates” as they are referred to by GCAL.

The GIA has the strongest global track record for independence and consistency. Because of to their continual coloration and clarity strictness guidelines, the globe’s premier and most expensive diamonds have been despatched there for grading a long time. In 2006, GIA-GTL additional a two-dimensional reduce grading program for round excellent diamonds.

AGS makes use of the strictest reduce expectations in the business. It makes use of a three-dimensional light overall performance metric that can quality several diamond styles. In truth, it is the only lower grading technique that is acknowledged by the scientific community.

What is a lot more, its Diamond High quality Document uses a exclusive and proprietary to 10 grading technique to evaluate the four Cs – a method which is easier to comprehend than GIA’s grading program. In reality, AGS even goes the additional action by equating their -ten rating scale to other types of ranking.

For case in point, the traditional VS1 diamond clarity rating is a three on the AGS Diamond High quality Doc.

Diamond Reporting – The Disadvantages

1. Diamond grading is not standardized or controlled and hence you may come throughout tier 2 labs that make use of looser tips to the tier 1 grading labs described over.

If you buy a diamond that has been graded by a tier 2 lab, you could conclude up having to pay a lot more for a lesser high quality diamond. So for case in point, a diamond rated a “F” in coloration at a tier 2 lab might get a G, H, or reduce shade rating at a far more trustworthy lab.

The business also reductions diamonds graded by lesser recognized labs by about fifteen-30% or more. So both you only purchase a diamond graded by a tier 1 lab or you accept that you might be buying a lesser good quality diamond than what is stated on the report if that diamond is graded by a lesser identified lab.

. two. A lot of massive chain merchants have enormous contracts with lesser known labs with “softer” diamond grading recommendations. Some of these softer labs place “recommended substitution values” on the lab stories – values which are larger than what shops intends market the diamonds for.

So a salesperson in a chain retailer might say to you, “Look at the excellent offer you are acquiring here. We are selling you this diamond engagement ring for $2500 but the report suggests that the advised replacement value is $4000.” Wow – what a offer – NOT! This is why it is much better that you trust only independent tier one labs.

Also bear in mind that trustworthy diamond grading stories are not appraisals and never provide appraisal figures. Diamond appraisals are often grossly inflated and are not anything you may want to rely on.

3. Diamond stories are riddled with disclaimers that specify that practically nothing is “certified” or assured and that the labs are not accountable for glitches. In reality, the GIA delivers a disclaimer of sorts on their site relating to the use of the term “certify.” The internet site states:

“It is incorrect to state that college students, graduates, their companies, or particular gemstones are “licensed” by GIA. The Gemological Institute of The usa does not certify any person or something. Neither a student nor a graduate who has been awarded a certification or diploma, nor a gem which has been graded or recognized by GIA has been certified by GIA”.

So it is achievable that you the client is left keeping the bag must an inaccuracy in a report is afterwards found. Courts have usually dominated that sellers, not labs, are responsible for this kind of errors. Why? Simply because the labs indicated beforehand that their reports could not be held liable.

Thankfully, there are a pair ways to give yourself more consumer protection:

A. You could fly to India the place jewelers provide a life time buyback plan to their buyers. Also costly to fly?

B. You could uncover one particular of the twenty% of US jewelers who sell fully bonded diamonds. These are diamonds that are sold with life time breakage, lifetime trade-in and life span buyback procedures.

C. Not as excellent a solution as getting a completely bonded diamond but you could get a diamond that will come with an actual “certificate” and not a report. “Accredited 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 appropriate. From a authorized standpoint, a diamond report is a simply an expert impression although in actuality, factors of a diamond grading report are not just viewpoints.

For illustration, a diamond’s carat (weight) can be accurately determined as nicely as its cut grade by measuring its optical performance or by referring to a personal computer product. A certificate on the other hand is a assertion of fact – a doc for which the issuer accepts legal obligation and will make restitution to the consumer for blunders.

Some top diamond grading labs provide each reports and certificates. AGS gives Diamond Good quality Files (non-qualified reviews) and also Diamond Top quality Certificates. Diamond Top quality Certificates are well prepared completely for AGS retail jewelers and offers guaranties from taking part American Gem Modern society member stores.

GCAL certifies it is diamond grading also. Its 100% income-back assure coverage is legitimate for a time period of two several years from the date on the relevant certification. This policy assures the precision of the lower, coloration and clarity grades and the carat excess weight.

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