Read The Diamond Grading Report Before Acquiring An Engagement Ring

Not all sellers give diamond grading lab reviews (aka diamond good quality reviews) to their customers. So my general suggestions to you is to maintain your money in your pocket when working with this sort of jewelers.

Only acquire a diamond engagement ring if it arrives with the authentic diamond good quality report.

A lab report is an unbiased evaluation of the 4Cs of a free diamond and includes a plotted diagram of the stone’s clarity attributes and a graphic illustration of the stone’s proportions. Having these kinds of a report allows you to compare diamonds of different characteristics and in the end will help you make a more informed buying determination.

A retailer may reduce corners and not offer a lab report or an unscrupulous vendor may provide a faux one since of the time, problems and expense he’ll bear to acquiring a stone graded.

Yeah – there is a cost for grading a diamond (although that price is at some point compensated by the customer), in addition the shipping and delivery and insurance coverage costs for sending the diamond to the lab. And permit us not neglect the opportunity expense of a jeweler not having the diamond in his keep for sale for a handful of months even though the grading will take location.

Nevertheless, a diamond grading report may possibly also not be offered simply because the charges to acquiring one may possibly influence way too greatly on the closing price of the ring.

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

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

The Premier Diamond Grading Lab Studies

Sure, all diamond quality stories are not created equivalent. Inside of the market, 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 Society Laboratories).

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

The GIA has the strongest global track record for independence and regularity. Because of to their consistent shade and clarity strictness guidelines, the globe’s greatest and most costly diamonds have been despatched there for grading many years. In 2006, GIA-GTL additional a two-dimensional minimize grading technique for spherical outstanding diamonds.

AGS utilizes the strictest reduce specifications in the industry. It employs a 3-dimensional gentle functionality metric that can grade a number of diamond styles. In simple fact, it is the only reduce grading technique that is regarded by the scientific neighborhood.

What is a lot more, its Diamond Quality Doc uses a distinctive and proprietary to 10 grading technique to appraise the 4 Cs – a system which is less complicated to understand than GIA’s grading technique. In simple fact, AGS even goes the added action by equating their -10 ranking scale to other types of ranking.

For case in point, the standard VS1 diamond clarity ranking is a three on the AGS Diamond Top quality Document.

Diamond Reporting – The Drawbacks

1. Diamond grading is not standardized or controlled and that’s why you may occur throughout tier two labs that use looser guidelines to the tier 1 grading labs described over.

If you get a diamond that has been graded by a tier 2 lab, you may end up paying out far more for a lesser good quality diamond. So for example, a diamond rated a “F” in colour at a tier two lab could get a G, H, or reduced shade score at a much more reputable lab.

The sector also reductions diamonds graded by lesser known labs by about 15-thirty% or much more. So possibly you only get a diamond graded by a tier 1 lab or you take that you may possibly be purchasing a lesser quality diamond than what is mentioned on the report if that diamond is graded by a lesser identified lab.

2. Numerous huge chain retailers have enormous contracts with lesser acknowledged labs with “softer” diamond grading suggestions. Some of these softer labs put “proposed alternative values” on the lab reports – values which are higher than what shops intends promote the diamonds for.

So a salesperson in a chain keep could say to you, “Appear at the great offer you are acquiring below. We are selling you this diamond engagement ring for $2500 but the report says that the suggested substitution price is $4000.” Wow – what a deal – NOT! This is why it is greater that you trust only independent tier 1 labs.

Also bear in head that trustworthy diamond grading studies are not appraisals and do not supply appraisal figures. Diamond appraisals are often grossly inflated and are not some thing you will want to rely on.

three. Diamond reviews are riddled with disclaimers that specify that practically nothing is “accredited” or guaranteed and that the labs are not accountable for errors. In simple fact, the GIA offers a disclaimer of types on their website regarding the use of the term “certify.” The website claims:

“It is incorrect to condition that learners, graduates, their companies, or particular gemstones are “licensed” by GIA. The Gemological Institute of The us does not certify anybody or anything at all. Neither a student nor a graduate who has been awarded a certificate or diploma, nor a gem which has been graded or determined by GIA has been certified by GIA”.

So it is attainable that you the client is remaining holding the bag must an inaccuracy in a report is later on found. Courts have frequently ruled that sellers, not labs, are liable for this sort of glitches. Why? Because the labs indicated beforehand that their reports could not be held liable.

Thankfully, there are a few techniques to give oneself much more purchaser security:

A. You could fly to India exactly where jewelers offer a life span buyback coverage to their customers. Way too expensive to fly?

B. You could locate one particular of the 20% of US jewelers who promote totally bonded diamonds. These are diamonds that are sold with life span breakage, life time trade-in and life span buyback guidelines.

C. Not as good a treatment as getting a completely bonded diamond but you could buy a diamond that arrives with an genuine “certificate” and not a report. “Licensed diamonds do occur with guaranties” albeit for shorter durations.


Some sellers refer to a “diamond report” as a “qualified diamond” but technically this is not correct. From a authorized standpoint, a diamond report is a just an expert view however in actuality, elements of a diamond grading report are not just viewpoints.

For instance, a diamond’s carat (bodyweight) can be precisely established as well as its reduce grade by measuring its optical performance or by referring to a pc design. A certificate on the other hand is a statement of fact – a document for which the issuer accepts authorized responsibility and will make restitution to the buyer for blunders.

Some top diamond grading labs supply equally stories and certificates. AGS provides Diamond High quality Paperwork (non-certified studies) and also Diamond Good quality Certificates. Diamond High quality Certificates are well prepared exclusively for AGS retail jewelers and offers guaranties from taking part American Gem Modern society member retailers.

GCAL certifies it’s diamond grading also. Its 100% cash-back again guarantee coverage is legitimate for a interval of two several years from the date on the relevant certificate. This coverage guarantees the precision of the lower, color and clarity grades and the carat excess weight.

A report or certificate need to will have a number on it that may possibly or may not be inscribed on a diamond. You will be capable to enter that quantity on the web site of the certifying lab to check out a report’s validity.
