Study The Diamond Grading Report Prior to Buying An Engagement Ring

Not all sellers offer diamond grading lab reviews (aka diamond quality reviews) to their buyers. So my general guidance to you is to hold your income in your pocket when dealing with these kinds of jewelers.

Only purchase a diamond engagement ring if it arrives with the first diamond high quality report.

A lab report is an unbiased analysis 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. Obtaining these kinds of a report makes it possible for you to examine diamonds of various characteristics and in the long run will help you make a far more informed buying selection 鑽石樓上鋪.

A retailer could lower corners and not offer a lab report or an unscrupulous vendor might supply a bogus one particular simply because of the time, problems and cost he’ll bear to getting a stone graded.

Yeah – there is a cost for grading a diamond (though that cost is ultimately paid out by the consumer), additionally the shipping and delivery and insurance policy charges for sending the diamond to the lab. And enable us not fail to remember the prospect value of a jeweler not getting the diamond in his store for sale for a few weeks even though the grading will take location.

However, a diamond grading report may also not be accessible due to the fact the fees to obtaining one could influence also heavily on the final price tag of the ring.

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

As you research for that best diamond engagement ring for your sweetheart, you will uncover that there is an alphabet soup of labs declaring to supply trustworthy diamond grading reviews. But I would only put my funds on…

The Premier Diamond Grading Lab Reports

Of course, all diamond high quality studies are not produced equal. Within 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 provides very regarded reports or “diamond certificates” as they are referred to by GCAL.

The GIA has the strongest worldwide reputation for independence and consistency. Thanks to their consistent color and clarity strictness suggestions, the globe’s largest and most expensive diamonds have been sent there for grading many years. In 2006, GIA-GTL additional a two-dimensional reduce grading technique for round amazing diamonds.

AGS uses the strictest minimize expectations in the market. It employs a 3-dimensional light-weight overall performance metric that can quality many diamond styles. In simple fact, it is the only lower grading method that is regarded by the scientific neighborhood.

What is more, its Diamond High quality Doc uses a exclusive and proprietary to 10 grading method to evaluate the four Cs – a method which is less complicated to understand than GIA’s grading method. In fact, AGS even goes the further phase by equating their -ten rating scale to other kinds of score.

For illustration, the traditional VS1 diamond clarity rating is a 3 on the AGS Diamond Top quality Document.

Diamond Reporting – The Disadvantages

1. Diamond grading is not standardized or regulated and that’s why you might come across tier 2 labs that make use of looser guidelines to the tier one grading labs mentioned previously mentioned.

If you buy a diamond that has been graded by a tier 2 lab, you might stop up having to pay far more for a lesser top quality diamond. So for example, a diamond rated a “F” in colour at a tier two lab may get a G, H, or decrease colour ranking at a a lot more respected lab.

The market also reductions diamonds graded by lesser known labs by about fifteen-thirty% or far more. So either you only get a diamond graded by a tier 1 lab or you settle for that you might be getting a lesser top quality diamond than what is stated on the report if that diamond is graded by a lesser recognized lab.

two. Many massive chain stores have massive contracts with lesser recognized labs with “softer” diamond grading tips. Some of these softer labs place “advised replacement values” on the lab reviews – values which are increased than what merchants intends market the diamonds for.

So a salesperson in a chain keep could say to you, “Seem at the excellent deal you are acquiring listed here. We are selling you this diamond engagement ring for $2500 but the report states that the recommended substitution value is $4000.” Wow – what a deal – NOT! This is why it is much better that you have faith in only unbiased tier 1 labs.

Also bear in brain that reliable diamond grading studies are not appraisals and never provide appraisal figures. Diamond appraisals are typically grossly inflated and are not some thing you’ll want to count on.

three. Diamond reviews are riddled with disclaimers that specify that absolutely nothing is “certified” or guaranteed and that the labs are not accountable for problems. In reality, the GIA delivers a disclaimer of kinds on their web site concerning the use of the word “certify.” The site states:

“It is incorrect to condition that learners, graduates, their businesses, or distinct gemstones are “accredited” by GIA. The Gemological Institute of The usa does not certify anybody or something. Neither a college student nor a graduate who has been awarded a certificate or diploma, nor a gem which has been graded or identified by GIA has been accredited by GIA”.

So it is achievable that you the buyer is still left holding the bag should an inaccuracy in a report is later uncovered. Courts have often dominated that sellers, not labs, are liable for such problems. Why? Simply because the labs indicated beforehand that their stories couldn’t be held liable.

Fortunately, there are a few approaches to give yourself much more consumer protection:

A. You could fly to India in which jewelers offer you a life span buyback coverage to their buyers. Also expensive to fly?

B. You could discover a single of the twenty% of US jewelers who market completely bonded diamonds. These are diamonds that are marketed with lifetime breakage, lifetime trade-in and life span buyback guidelines.

C. Not as very good a cure as purchasing a entirely bonded diamond but you could purchase a diamond that arrives with an actual “certification” and not a report. “Qualified diamonds do come with guaranties” albeit for shorter durations.


Some sellers refer to a “diamond report” as a “licensed diamond” but technically this is not correct. From a legal standpoint, a diamond report is a just an professional viewpoint however in actuality, factors of a diamond grading report are not just viewpoints.

For example, a diamond’s carat (bodyweight) can be properly identified as well as its cut grade by measuring its optical performance or by referring to a laptop product. A certificate on the other hand is a assertion of reality – a doc for which the issuer accepts authorized accountability and will make restitution to the client for errors .

Some prime diamond grading labs supply equally stories and certificates. AGS offers Diamond High quality Files (non-licensed reviews) and also Diamond High quality Certificates. Diamond Quality Certificates are prepared completely for AGS retail jewelers and delivers guaranties from taking part American Gem Modern society member shops.

GCAL certifies it is diamond grading also. Its one hundred% cash-back again ensure coverage is legitimate for a time period of two years from the day on the relevant certification. This policy assures the accuracy of the reduce, coloration and clarity grades and the carat weight.

A report or certificate should will have a number on it that could or could not be inscribed on a diamond. You will be in a position to enter that quantity on the website of the certifying lab to examine a report’s validity.
