Not all sellers provide diamond grading lab studies (aka diamond good quality reports) to their particular consumers. So my general advice to be able to you is in order to maintain your money in your pocket any time dealing with many of these jewelers.

Only purchase a diamond engagement diamond ring whether it comes with the original diamonds quality report.

A new lab report is definitely an independent evaluation of the 4Cs of a loose diamond plus features a plotted picture of the stone’s clarity characteristics and the graphic representation of the stone’s amounts. Having such some sort of report allows you to compare gemstones of different characteristics and ultimately assists you create an extra informed buying decision.

A retailer might cut corners and even not provide the lab report or perhaps an unscrupulous retailer may provide some sort of fake one since of the period, trouble and expense he’ll bear to be able to getting a stone graded.

Yeah — there is some sort of price for grading a diamond (though that value is sooner or later paid with the consumer), plus the delivery and insurance costs for sending the particular diamond to the lab. And permit us remember the opportunity cost involving a jeweler not having the diamonds in his retail outlet for sale regarding a few several weeks while the grading happens.

However, a diamond grading record could also not end up being available as the expenses to getting one could impact too greatly on the final price in the ring.

For example, some sort of 0. 3ct engagement ring costing $250 say, may cost close to $75 to end up being graded and possess the report number inscribed on typically the girdle on the diamond.

When you search for that ideal diamond engagement diamond ring to your sweetheart, likely to find that it comes with an alphabet soup of labs claiming to provide reputable diamond grading reports. But We would only put our money on…

The Premier Diamond Grading Lab Reports

Sure, all diamond quality reports are not really created equal. Within the industry, this can be a consensus that the 2 premier labs happen to be GIA-GTL (Gemological Initiate of America’s Gem Trade Lab) along with the AGS (American Treasure Society Laboratories).

The GCAL (Gem Qualification and Assurance Lab) also offers very regarded reports or perhaps “diamond certificates” while they are referenced to by GCAL.

The GIA features the strongest global reputation for independence and consistency. Due to their constant color and clarity strictness guidelines, the globe’s most significant and most costly diamonds have already been sent there intended for grading decades. Throughout 2006, GIA-GTL added a two-dimensional cut grading system regarding round brilliant diamonds.

AGS uses typically the strictest cut criteria in the business. It uses some sort of three-dimensional light efficiency metric that may grade several precious stone shapes. In fact, it is the particular only cut grading system that is usually recognized by typically the scientific community.

What is more, its Diamond Top quality Document uses an unique and proprietary 0 to 10 grading system to examine the 4 Cs – a method which is simpler to comprehend than GIA’s grading system. In fact , AGS even should go the extra phase by equating their very own 0-10 rating level to forms associated with rating.

For instance , typically the conventional VS1 gemstone clarity rating is a 3 on the particular AGS Diamond Quality Document.

Diamond Reporting – The Downsides

1 ) Diamond grading is not really standardized or perhaps regulated and therefore you may encounter tier 2 amenities that employ looser guidelines to typically the tier 1 grading labs mentioned above.

If you get a diamond that has been rated by a tier 2 lab, an individual may finish up paying out more for any lower quality diamond. Thus for example, a diamond rated some sort of “F” in color at a tier 2 lab may well get a Gary the gadget guy, H, or reduce color rating at a more reputable lab.

The sector also discounts expensive diamonds graded by reduced known labs by simply about 15-30% or even more. Aquamarin So either you simply buy a diamonds graded by the tier 1 lab or you accept that you may be buying a smaller quality diamond than is stated around the record if that diamonds is graded by simply a lesser acknowledged lab.

2. Numerous large chain stores have huge long term contracts with lesser acknowledged labs with “softer” diamond grading recommendations. Some of these types of softer labs set “suggested replacement values” for the lab studies – values which in turn are greater than exactly what stores intends market the diamonds intended for.

So a salesman found in a chain retail store may say to be able to you, “Look in the good deal you are getting below. We are selling you this gemstone gemstone for $2500 nevertheless the report claims the suggested substitute value is $4000. ” Wow – exactly what an university deal instructions NOT! This is definitely why it will be better which you have confidence in only independent rate 1 labs.

Likewise bear in mind that reputable diamonds grading reports are generally not appraisals and avoid offer appraisal statistics. Diamond appraisals happen to be often grossly filled with air and are not necessarily something you’ll would like to rely on.

three or more. Diamond reports are generally riddled with disclaimers that specify that nothing is “certified” or guaranteed in addition to that the amenities are not liable for errors. In fact, the GIA offers a please note of sorts in their website regarding the use of typically the word “certify. ” The website states:

“It is inappropriate to state that students, graduates, their very own businesses, or particular gemstones are “certified” by GIA. Typically the Gemological Institute involving America does not really certify anyone or perhaps anything. Neither the student nor a new graduate who provides been awarded the certificate or degree, nor a gem that can be graded or identified by GIA have been certified by GIA”.

So it is possible of which the consumer will be left holding the bag should the inaccuracy in a new report is after discovered. Courts have got frequently ruled that sellers, not labratories, are responsible for such errors. Exactly why? As the labs indicated beforehand that their own reports couldn’t become held liable.

Thankfully, a few couple ways to give oneself more buyer safety:

A. You could travel to India exactly where jewelers provide a life time buyback policy in order to their customers. Too costly to fly?

N. You could locate one of typically the 20% of ALL OF US jewelers who offer fully bonded diamonds. These are diamond jewelry that are marketed with lifetime damage, lifetime trade-in in addition to lifetime buyback plans.

C. Less great a remedy simply because buying a fully bonded diamond yet you could buy a diamond that is included with an actual “certificate” and not a report. “Certified diamonds do come with guaranties” albeit for smaller durations.


Several sellers refer to be able to a “diamond report” as a “certified diamond” but technically this particular is not right. From a lawful standpoint, a gemstone report is the simply a professional thoughts and opinions though in fact, aspects of a diamonds grading report are generally not just opinions.

For instance , a diamond’s karat (weight) can be accurately determined as well as the cut grade by simply measuring its optic efficiency or simply by referring to some sort of computer model. Some sort of certificate however is a new statement of fact – a doc for which the particular issuer accepts legal responsibility and will make restitution to typically the consumer for mistakes.

Some top gemstone grading labs offer both reports in addition to certificates. AGS gives Diamond Quality Paperwork (non-certified reports) and even also Diamond Good quality Certificates. Diamond Quality Certificates are well prepared exclusively for AGS retail jewelers and offers guaranties from participating American Jewel Society member retailers.

GCAL certifies it’s diamond grading in addition. Its 100% refund guarantee policy is valid for a new period of two years from typically the date on typically the applicable certificate. This policy ensures the accuracy of the cut, color and quality grades along with the carat weight.

A review or certificate should may have an amount on it which could or may not really be inscribed on a diamond. It will be easy to enter that number on the site associated with the certifying laboratory to check a report’s validity.

Components Of A Diamond Grading Review

Diamond grading reports will be always evolving yet certain element should remain the identical. As an example, the:

Typically the Report #. This number is specific and recorded inside a lab’s record and may or perhaps may not be inscribed on a diamond’s girdle.

Colour Grade: This lets you know the level involving color absence inside the diamond. Typically the less color the better the grading.

Diamonds are commonly graded from D-Z; the closer in order to “D” the white the diamond. A person should never find diamond color range for example (G-H, I-J-K, and thus on) in a diamond review. You should only see color varies on appraisals intended for stones that are really mounted.

Clarity Quality: Just about any diamond has internal imperfections referred to as inclusions and outside imperfections called spots. A diamond will be graded according to the size, variety, location and quantity of these flaws.
