Not all sellers offer diamond grading lab studies (aka diamond high quality stories) to their consumers. So my basic tips to you is to preserve your money in your pocket when working with this sort of jewelers.

Only obtain a diamond engagement ring if it will come with the original diamond quality report.

A lab report is an independent evaluation of the 4Cs of a loose diamond and includes a plotted diagram of the stone’s clarity qualities and a graphic illustration of the stone’s proportions. Getting this sort of a report allows you to evaluate diamonds of different traits and in the end aids you make a a lot more educated getting determination 結婚戒指.

A retailer may possibly reduce corners and not supply a lab report or an unscrupulous vendor may possibly supply a fake a single since of the time, difficulty and cost he’ll bear to obtaining a stone graded.

Yeah – there is a cost for grading a diamond (however that value is ultimately compensated by the customer), furthermore the shipping and insurance fees for sending the diamond to the lab. And permit us not fail to remember the possibility expense of a jeweler not getting the diamond in his keep for sale for a couple of months even though the grading will take place.

Even so, a diamond grading report could also not be accessible due to the fact the fees to getting one particular could affect too heavily on the ultimate price of the ring.

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

As you look for for that ideal diamond engagement ring for your sweetheart, you’ll locate that there is an alphabet soup of labs declaring to supply reputable diamond grading stories. But I would only put my cash on…

The Leading Diamond Grading Lab Reviews

Of course, all diamond quality reviews are not produced equal. In 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 Culture Laboratories).

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

The GIA has the strongest international reputation for independence and regularity. Because of to their constant colour and clarity strictness suggestions, the globe’s premier and most pricey diamonds have been despatched there for grading decades. In 2006, GIA-GTL extra a two-dimensional reduce grading program for round excellent diamonds.

AGS makes use of the strictest minimize expectations in the business. It makes use of a 3-dimensional light performance metric that can grade numerous diamond styles. In truth, it is the only lower grading system that is acknowledged by the scientific group.

What is much more, its Diamond Good quality Document makes use of a exclusive and proprietary to 10 grading program to consider the 4 Cs – a method which is less complicated to understand than GIA’s grading technique. In simple fact, AGS even goes the additional action by equating their -ten rating scale to other types of ranking.

For example, the traditional VS1 diamond clarity ranking is a 3 on the AGS Diamond High quality Document.

Diamond Reporting – The Downsides

1. Diamond grading is not standardized or controlled and hence you might occur throughout tier two labs that employ looser recommendations to the tier one grading labs pointed out earlier mentioned.

If you purchase a diamond that has been graded by a tier two lab, you may possibly end up paying out more for a lesser top quality diamond. So for instance, a diamond rated a “F” in color at a tier two lab could get a G, H, or lower colour rating at a a lot more respected lab.

The business also discount rates diamonds graded by lesser recognized labs by about fifteen-thirty% or more. So both you only buy a diamond graded by a tier 1 lab or you take that you may possibly be purchasing a lesser quality diamond than what is said on the report if that diamond is graded by a lesser acknowledged lab.

two. Several huge chain retailers have huge contracts with lesser identified labs with “softer” diamond grading guidelines. Some of these softer labs set “suggested alternative values” on the lab reports – values which are larger than what stores intends promote the diamonds for.

So a salesperson in a chain retailer may say to you, “Seem at the excellent deal you are getting right here. We are selling you this diamond engagement ring for $2500 but the report states that the proposed replacement price is $4000.” Wow – what a deal – NOT! This is why it is much better that you trust only impartial tier 1 labs.

Also bear in head that reliable diamond grading studies are not appraisals and will not provide appraisal figures. Diamond appraisals are typically grossly inflated and are not some thing you are going to want to rely on.

three. Diamond studies are riddled with disclaimers that specify that nothing is “licensed” or certain and that the labs are not accountable for problems. In fact, the GIA offers a disclaimer of types on their internet site regarding the use of the phrase “certify.” The internet site claims:

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

So it is achievable that you the customer is remaining keeping the bag should an inaccuracy in a report is afterwards identified. Courts have often ruled that sellers, not labs, are accountable for such problems. Why? Due to the fact the labs indicated beforehand that their stories couldn’t be held liable .

The good news is, there are a pair techniques to give by yourself a lot more purchaser safety:

A. You could fly to India where jewelers offer a lifetime buyback plan to their customers. Way too costly to fly?

B. You could locate one of the 20% of US jewelers who sell entirely bonded diamonds. These are diamonds that are sold with life span breakage, lifetime trade-in and lifetime buyback insurance policies.

C. Not as good a remedy as buying a completely bonded diamond but you could get 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 appropriate. From a authorized standpoint, a diamond report is a simply an skilled impression though in actuality, facets of a diamond grading report are not just viewpoints.

For illustration, a diamond’s carat (bodyweight) can be accurately determined as properly as its cut grade by measuring its optical efficiency or by referring to a personal computer product. A certification on the other hand is a assertion of reality – a doc for which the issuer accepts lawful duty and will make restitution to the consumer for blunders.

Some prime diamond grading labs supply both reports and certificates. AGS offers Diamond Quality Files (non-licensed stories) and also Diamond High quality Certificates. Diamond High quality Certificates are prepared completely for AGS retail jewelers and provides guaranties from taking part American Gem Culture member merchants.

GCAL certifies it is diamond grading also. Its 100% money-back assure policy is legitimate for a period of two many years from the day on the applicable certification. This coverage guarantees the precision of the minimize, coloration and clarity grades and the carat weight.

A report or certificate ought to will have a amount on it that could or may possibly not be inscribed on a diamond. You will be capable to enter that variety on the internet site of the certifying lab to examine a report’s validity.

Elements Of A Diamond Grading Report

Diamond grading reviews are often evolving but certain aspect must remain the exact same. For instance, the:

Coloration Quality: This tells you the degree of shade absence in the diamond. The significantly less colour the higher the quality.
