Go through The Diamond Grading Report Ahead of Acquiring An Engagement Ring

Not all sellers provide diamond grading lab studies (aka diamond top quality studies) to their shoppers. So my common tips to you is to keep your cash in your pocket when dealing with these kinds of jewelers.

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

A lab report is an independent analysis of the 4Cs of a unfastened diamond and contains a plotted diagram of the stone’s clarity characteristics and a graphic representation of the stone’s proportions. Possessing such a report enables you to assess diamonds of distinct attributes and eventually assists you make a far more knowledgeable purchasing determination.

A retailer may cut corners and not provide a lab report or an unscrupulous seller could offer a fake a single since of the time, difficulties and cost he’ll bear to acquiring a stone graded.

Yeah – there is a cost for grading a diamond (however that price is sooner or later paid out by the customer), furthermore the shipping and insurance policies charges for sending the diamond to the lab. And permit us not neglect the possibility expense of a jeweler not getting the diamond in his shop for sale for a couple of weeks although the grading takes area.

Nonetheless, a diamond grading report could also not be accessible because the fees to obtaining a single may impact too seriously on the ultimate cost of the ring.

For example, a .3ct diamond ring costing $250 say, could cost close to $75 to be graded and have the report amount inscribed on the girdle on the diamond.

As you search for that best diamond engagement ring for your sweetheart, you are going to find that there is an alphabet soup of labs claiming to provide reliable diamond grading reviews. But I would only put my funds on…

The Leading Diamond Grading Lab Reports

Yes, all diamond quality reviews are not created equal. Within 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 Society Laboratories).

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

The GIA has the strongest worldwide track record for independence and regularity. Thanks to their continual shade and clarity strictness guidelines, the globe’s greatest and most costly diamonds have been sent there for grading a long time. In 2006, GIA-GTL included a two-dimensional lower grading technique for spherical amazing diamonds.

AGS employs the strictest reduce requirements in the sector. It utilizes a a few-dimensional light functionality metric that can quality many diamond designs. In simple fact, it is the only minimize grading program that is identified by the scientific community.

What is a lot more, its Diamond High quality Doc uses a distinctive and proprietary to ten grading technique to evaluate the four Cs – a program which is less difficult to understand than GIA’s grading system. In simple fact, AGS even goes the additional step by equating their -ten rating scale to other kinds of score.

For case in point, the conventional VS1 diamond clarity ranking is a three on the AGS Diamond Quality Document.

Diamond Reporting – The Downsides

1. Diamond grading is not standardized or controlled and hence you could appear throughout tier 2 labs that make use of looser recommendations to the tier 1 grading labs mentioned earlier mentioned.

If you buy a diamond that has been graded by a tier 2 lab, you may stop up paying far more for a lesser top quality diamond. So for illustration, a diamond rated a “F” in colour at a tier 2 lab may get a G, H, or lower coloration ranking at a far more reliable lab.

The industry also discount rates diamonds graded by lesser identified labs by about fifteen-thirty% or a lot more. So possibly you only purchase a diamond graded by a tier one lab or you take that you might be purchasing a lesser quality diamond than what is said on the report if that diamond is graded by a lesser recognized lab.

two. Many large chain retailers have massive contracts with lesser known labs with “softer” diamond grading recommendations. Some of these softer labs put “suggested replacement values” on the lab stories – values which are larger than what merchants intends promote the diamonds for.

So a salesperson in a chain store might say to you, “Appear at the excellent deal you are receiving here. We are marketing you this diamond engagement ring for $2500 but the report claims that the suggested replacement price is $4000.” Wow – what a deal – NOT! This is why it is much better that you trust only independent tier one labs.

Also bear in brain that reputable diamond grading stories are not appraisals and do not provide appraisal figures. Diamond appraisals are usually grossly inflated and are not something you’ll want to rely on.

3. Diamond reviews are riddled with disclaimers that specify that practically nothing is “accredited” or guaranteed and that the labs are not accountable for glitches. In fact, the GIA gives a disclaimer of kinds on their site relating to the use of the word “certify.” The internet site claims:

“It is incorrect to condition that learners, graduates, their businesses, or particular gemstones are “qualified” by GIA. The Gemological Institute of The us does not certify anyone or anything at all. Neither a pupil nor a graduate who has been awarded a certificate or diploma, nor a gem which has been graded or discovered by GIA has been qualified by GIA”.

So it is achievable that you the buyer is still left holding the bag should an inaccuracy in a report is later on discovered. Courts have frequently ruled that sellers, not labs, are liable for this kind of glitches. Why? Since the labs indicated beforehand that their reports couldn’t be held liable.

Fortunately, there are a pair techniques to give oneself far more buyer protection:

A. You could fly to India exactly where jewelers provide a life span buyback plan to their customers. As well pricey to fly?

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

C. Not as great a solution as purchasing a completely bonded diamond but you could acquire a diamond that will come with an genuine “certification” and not a report. “Certified diamonds do appear with guaranties” albeit for shorter durations.


Some sellers refer to a “diamond report” as a “qualified diamond” but technically this is not appropriate. From 鑽石 authorized standpoint, a diamond report is a simply an skilled impression even though in actuality, elements of a diamond grading report are not just thoughts.

For example, a diamond’s carat (excess weight) can be precisely determined as properly as its cut grade by measuring its optical effectiveness or by referring to a pc product. A certification on the other hand is a assertion of simple fact – a doc for which the issuer accepts authorized duty and will make restitution to the buyer for blunders.

Some top diamond grading labs offer each studies and certificates. AGS provides Diamond Quality Paperwork (non-qualified stories) and also Diamond Top quality Certificates. Diamond Top quality Certificates are geared up exclusively for AGS retail jewelers and provides guaranties from collaborating American Gem Modern society member merchants.

GCAL certifies it is diamond grading also. Its a hundred% income-back again ensure coverage is valid for a period of time of two years from the day on the relevant certification. This policy guarantees the accuracy of the cut, color and clarity grades and the carat excess weight.

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

Components Of A Diamond Grading Report

Diamond grading reports are usually evolving but specific aspect should continue to be the exact same. For instance, the:

The Report #. This variety is offered and recorded in a lab’s report and might or may not be inscribed on a diamond’s girdle. You can enter the report number on a grading lab’s site to check the authenticity of the diamond top quality report or to get a lot more information about the diamond.

Carat Excess weight: The fat of a diamond is calculated to the hundredth of a carat and some even provide this kind of evaluate to the thousandth of a carat (1.123ct.). Carat is the most goal and the least difficult to recognize of the 4Cs since all one particular has to do is weight the stone.

Color Grade: This tells you the level of color absence in the diamond. The significantly less coloration the larger the quality.

Diamonds are normally graded from D-Z the closer to “D” the whiter the diamond. You need to by no means see diamond shade selection these kinds of as (G-H, I-J-K, and so on) on a diamond report. You need to only see shade ranges on appraisals for stones that are mounted.

Clarity Grade: Nearly each diamond has internal imperfections named inclusions and exterior imperfections called blemishes. A diamond is graded according to the measurement, sort, area and amount of these flaws.

Clarity grades range from Flawless (FL) – Provided. Labs use a couple specialists to quality the clarity of a diamond in get to come up with a more accurate reading.
