Study The Diamond Grading Report Ahead of Acquiring An Engagement Ring


Not all sellers provide diamond grading lab reports (aka diamond good quality reports) to their buyers. So my standard advice to you is to maintain your income in your pocket when dealing with this sort of jewelers.

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

A lab report is an unbiased analysis of the 4Cs of a free diamond and contains a plotted diagram of the stone’s clarity attributes and a graphic illustration of the stone’s proportions. Obtaining these kinds of a report makes it possible for you to evaluate diamonds of distinct attributes and in the long run assists you make a a lot more informed purchasing choice 鑽戒.

A retailer may possibly cut corners and not supply a lab report or an unscrupulous seller may supply a phony 1 since of the time, difficulties and expenditure he’ll bear to obtaining a stone graded.

Yeah – there is a cost for grading a diamond (however that price is sooner or later compensated by the client), in addition the shipping and delivery and insurance charges for sending the diamond to the lab. And let us not overlook the opportunity cost of a jeweler not possessing the diamond in his retailer for sale for a number of months even though the grading will take place.

Nevertheless, a diamond grading report might also not be offered simply because the costs to receiving a single may possibly effect too seriously on the last value of the ring.

For example, a . 3ct diamond ring costing $250 say, might price about $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 may discover that there is an alphabet soup of labs declaring to provide reputable diamond grading reviews. But I would only place my money on…

The Premier Diamond Grading Lab Reviews

Indeed, all diamond top quality studies are not produced equivalent. Within the business, 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 very regarded stories or “diamond certificates” as they are referred to by GCAL.

The GIA has the strongest international status for independence and regularity. Due to their constant coloration and clarity strictness guidelines, the globe’s largest and most costly diamonds have been despatched there for grading many years. In 2006, GIA-GTL extra a two-dimensional cut grading method for spherical excellent diamonds.

AGS makes use of the strictest cut standards in the sector. It employs a a few-dimensional mild functionality metric that can grade a number of diamond shapes. In truth, it is the only reduce grading program that is identified by the scientific neighborhood.

What is far more, its Diamond Top quality Doc makes use of a distinctive and proprietary to ten grading program to evaluate the 4 Cs – a technique which is simpler to understand than GIA’s grading program. In fact, AGS even goes the further stage by equating their -ten ranking scale to other types of rating.

For instance, the traditional VS1 diamond clarity score is a 3 on the AGS Diamond High quality Doc.

Diamond Reporting – The Drawbacks

1. Diamond grading is not standardized or regulated and hence you could appear throughout tier two labs that make use of looser recommendations to the tier one grading labs mentioned above.

If you get a diamond that has been graded by a tier two lab, you may possibly finish up paying a lot more for a lesser high quality diamond. So for instance, a diamond rated a “F” in coloration at a tier 2 lab could get a G, H, or reduced color score at a a lot more reliable lab.

The market also discounts diamonds graded by lesser known labs by about 15-thirty% or more. So both you only acquire a diamond graded by a tier 1 lab or you settle for that you may possibly be getting a lesser top quality diamond than what is said on the report if that diamond is graded by a lesser recognized lab.

two. Several massive chain stores have enormous contracts with lesser identified labs with “softer” diamond grading tips. Some of these softer labs set “advised substitution values” on the lab studies – values which are greater than what shops intends sell the diamonds for.

So a salesperson in a chain store could say to you, “Look at the great offer you are getting listed here. We are promoting you this diamond engagement ring for $2500 but the report suggests that the advised replacement worth is $4000.” Wow – what a deal – NOT! This is why it is much better that you have confidence in only unbiased tier one labs.

Also bear in thoughts that respected diamond grading reviews are not appraisals and will not provide appraisal figures. Diamond appraisals are often grossly inflated and are not something you will 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 errors. In reality, the GIA gives a disclaimer of types on their internet site regarding the use of the term “certify.” The internet site suggests:

“It is incorrect to point out that college students, graduates, their companies, or certain gemstones are “qualified” by GIA. The Gemological Institute of America does not certify any person or anything at all. Neither a scholar nor a graduate who has been awarded a certification or diploma, nor a gem which has been graded or identified by GIA has been qualified by GIA”.

So it is attainable that you the buyer is remaining keeping the bag should an inaccuracy in a report is later on identified. Courts have regularly ruled that sellers, not labs, are liable for these kinds of glitches. Why? Due to the fact the labs indicated beforehand that their reports couldn’t be held liable.

Fortunately, there are a few methods to give yourself much more consumer safety:

A. You could fly to India exactly where jewelers provide a life span buyback policy to their buyers. Also pricey to fly?

B. You could uncover a single of the 20% of US jewelers who sell entirely bonded diamonds. These are diamonds that are offered with lifetime breakage, lifetime trade-in and lifetime buyback procedures.

C. Not as very good a treatment as purchasing a fully bonded diamond but you could purchase a diamond that comes with an true “certificate” and not a report. “Accredited diamonds do arrive with guaranties” albeit for shorter durations.


Some sellers refer to a “diamond report” as a “qualified diamond” but technically this is not right. From a lawful standpoint, a diamond report is a simply an skilled opinion though in actuality, factors of a diamond grading report are not just opinions.

For case in point, a diamond’s carat (weight) can be precisely decided as effectively as its cut quality by measuring its optical efficiency or by referring to a personal computer design. A certification 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 problems.

Some best diamond grading labs offer you both stories and certificates. AGS delivers Diamond Top quality Documents (non-accredited reviews) and also Diamond Good quality Certificates. Diamond High quality Certificates are ready exclusively for AGS retail jewelers and delivers guaranties from participating American Gem Society member shops.

GCAL certifies it is diamond grading also. Its a hundred% funds-back again assure coverage is legitimate for a time period of two several years from the day on the applicable certification. This policy guarantees the precision of the cut, shade and clarity grades and the carat weight.

A report or certification should will have a number on it that might or may not be inscribed on a diamond. You will be able to enter that amount on the web site of the certifying lab to verify a report’s validity.

Elements Of A Diamond Grading Report

Diamond grading stories are always evolving but specific component need to continue being the very same. For instance, the:

The Report #. This amount is provided and recorded in a lab’s file and may or may possibly not be inscribed on a diamond’s girdle. You can enter the report variety on a grading lab’s web site to examine the authenticity of the diamond high quality report or to get more data about the diamond.

There are 3 fundamental side designs – “excellent cut, action reduce and blended chopping type” and twelve fundamental designs which consist of notables these kinds of as spherical amazing and princess reduce” diamonds.

Measurements: This refers to dimension (not excess weight) of a diamond. Measurement contains dimensions these kinds of as size, width, bodyweight and diameter. A measurement is typically listed to the hundredth of a millimeter. Measurements engage in a massive position in how a diamond sparkles.

Carat Bodyweight: The weight of a diamond is measured to the hundredth of a carat and some even give these kinds of evaluate to the thousandth of a carat (1.123ct.). Carat is the most aim and the easiest to recognize of the 4Cs since all 1 has to do is fat the stone.

Coloration Grade: This tells you the stage of colour absence in the diamond. The less shade the larger the grade.

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

Clarity Quality: Almost every single diamond has inner imperfections called inclusions and exterior imperfections known as blemishes. A diamond is graded in accordance to the dimensions, variety, area and quantity of these flaws.

Clarity grades variety from Flawless (FL) – Provided. Labs use a few specialists to grade the clarity of a diamond in purchase to occur up with a much more precise studying.

Cut Grade: A lot more current diamond studies consist of a lower grade for normal round excellent diamonds. Minimize requires into consideration the brilliance, fire and scintillation of the diamond. Cut grade ranges from Excellent – Very poor.
