Not all sellers provide gemstone grading lab studies (aka diamond high quality reports) to their own consumers. So my general advice to you is to be able to keep money in your pocket any time dealing with such jewelers.

Only buy a diamond engagement band whether it comes using the original gemstone quality report.

The lab report is definitely an independent evaluation from the 4Cs of a loose diamond and features a plotted plan with the stone’s clearness characteristics and the graphic representation associated with the stone’s dimensions. Having such a report allows you to compare diamond jewelry of different characteristics and ultimately assists you make an extra informed buying selection.

A retailer may well cut corners in addition to not provide the lab report or even an unscrupulous retailer may provide a new fake one because of the time, trouble and cost he’ll bear to getting a rock graded.

Yeah — there is a price for grading a diamond (though that cost is ultimately paid from the consumer), plus the shipping and delivery and insurance costs for sending typically the diamond to the particular lab. And allow us not forget typically the opportunity cost regarding a jeweler certainly not having the precious stone in his retail store for sale for a few several weeks while the grading occurs.

However, a diamond grading statement might also not become available because the fees to getting you can impact too intensely on the final price in the ring.

For example, a new 0. 3ct band costing $250 state, may cost around $75 to end up being graded and include the report number inscribed on the particular girdle on the diamond.

When you lookup for that excellent diamond engagement band for the sweetheart, likely to find that it has an alphabet soup of labs claiming to deliver reputable diamond grading reports. Aquamarin But I would only put the money on…

The particular Premier Diamond Grading Lab Reports

Of course, all diamond good quality reports are not necessarily of the same quality. Within the industry, this is a general opinion that the a couple of premier labs will be GIA-GTL (Gemological Start of America’s Jewel Trade Lab) and the AGS (American Treasure Society Laboratories).

The GCAL (Gem Documentation and Assurance Lab) also offers extremely regarded reports or even “diamond certificates” while they are referred to by GCAL.

The GIA features the strongest international reputation for self-reliance and consistency. Because of the constant color and even clarity strictness guidelines, the globe’s biggest and most pricey diamonds have recently been sent there for grading decades. In 2006, GIA-GTL extra a two-dimensional trim grading system intended for round brilliant expensive diamonds.

AGS uses the strictest cut specifications in the sector. It uses some sort of three-dimensional light functionality metric that may grade several precious stone shapes. In reality, it is the only cut grading system that is usually recognized by the scientific community.

What is more, its Diamond Quality Document uses a special and proprietary zero to 10 grading system to assess the 4 Cs – a program which is much easier to comprehend than GIA’s grading system. In fact , AGS even moves the extra stage by equating their very own 0-10 rating level some other forms involving rating.

For instance , the conventional VS1 gemstone clarity rating is really a 3 on the particular AGS Diamond Good quality Document.

Diamond Credit reporting – The Drawbacks

1 . Diamond grading is not standardized or perhaps regulated and consequently you may encounter tier 2 labratories that employ sagging guidelines to the tier 1 grading labs mentioned above.

If you get a diamond that has been scored by a tier 2 lab, you may end up paying out more for any lesser quality diamond. And so for example, the diamond rated some sort of “F” in colour at a rate 2 lab may get a Grams, H, or reduce color rating at a more trustworthy lab.

The sector also discounts gemstones graded by smaller known labs simply by about 15-30% or even more. So either you only buy a precious stone graded by the tier 1 research laboratory or you recognize that you may well be buying a smaller quality diamond than what is stated within the statement if that precious stone is graded simply by a lesser acknowledged lab.

2. A lot of large chain shops have huge long term contracts with lesser identified labs with “softer” diamond grading suggestions. Some of these softer labs set “suggested replacement values” for the lab reviews – values which often are higher than exactly what stores intends market the diamonds with regard to.

So a salesperson in a chain retail store may say in order to you, “Look with the great deal you are getting right here. We are advertising you this diamonds engagement ring for $2500 but the report states the suggested substitute value is $4000. ” Wow instructions exactly what a deal instructions NOT! This is usually why it is definitely better that you simply trust only independent rate 1 labs.

Also bear in head that reputable gemstone grading reports are not appraisals and no longer offer appraisal figures. Diamond appraisals are often grossly inflated and are not necessarily something you’ll need to depend on.

a few. Diamond reports are really riddled with disclaimers that specify of which nothing is “certified” or guaranteed and that the amenities are not responsible for errors. Inside fact, the GIA offers a please note of sorts in their website about the use of typically the word “certify. inches The website says:

“It is incorrect to state of which students, graduates, their businesses, or particular gemstones are “certified” by GIA. Typically the Gemological Institute regarding America does not really certify anyone or anything. Neither some sort of student nor the graduate who provides been awarded a new certificate or diploma, nor a jewel which has been graded or even identified by GIA has become certified by GIA”.

So this is possible that will you the consumer is left holding the bag should a good inaccuracy in a report is afterwards discovered. Courts include frequently ruled that sellers, not amenities, are responsible regarding such errors. Why? Since the labs suggested beforehand that their reports couldn’t be held liable.

Thankfully, a large couple techniques to give oneself more buyer protection:

A. You can travel to India exactly where jewelers provide a life span buyback policy to their customers. Pricy to fly?

W. You could discover one of the particular 20% of US ALL jewelers who sell off fully bonded diamond jewelry. These are diamond jewelry that are offered with lifetime the break point, lifetime trade-in in addition to lifetime buyback guidelines.

C. Much less good a remedy just as buying a totally bonded diamond but you could acquire a diamond that is included with an actual “certificate” rather than a report. “Certified diamonds do come with guaranties” albeit for smaller durations.


Some sellers refer to a “diamond report” as being a “certified diamond” but technically this is not right. From a lawful standpoint, a gemstone report is a new simply an expert opinion though in actuality, factors of a diamonds grading report are generally not just opinions.

For instance , a diamond’s carat (weight) can be accurately determined seeing that well as it is cut grade by measuring its optical efficiency or simply by referring to some sort of computer model. The certificate on the other hand is a new statement of reality – a file for which the particular issuer accepts legal responsibility and will help make restitution to typically the consumer for faults.

Some top diamonds grading labs present both reports and certificates. AGS presents Diamond Quality Files (non-certified reports) and also Diamond Top quality Certificates. Diamond Top quality Certificates are prepared exclusively for AGS retail jewelers and offers guaranties coming from participating American Gemstone Society member retailers.

GCAL certifies it’s diamond grading likewise. Its 100% refund guarantee policy is valid for some sort of period of two years from the particular date on typically the applicable certificate. This kind of policy ensures typically the accuracy with the lower, color and clarity grades along with the carat weight.

A report or certificate ought to may have a number on it that may or may not necessarily be inscribed in a diamond. You will be able to enter of which number on the website associated with the certifying research laboratory to check a report’s validity.

Elements Of A Diamond Grading Report

Gemstone grading reports are always evolving although certain element should remain the identical. For instance, the:

The Report #. This particular number is particular and recorded throughout a lab’s file and may or may not become inscribed on a new diamond’s girdle.
