Dear GIA Laboratory Client,

The revised GIA laboratory services for D-to-Z laboratory-grown diamonds will launch on October 1. Current GIA laboratory services for D-to-Z laboratory-grown diamonds will be available until September 30. This update to our services was announced in a GIA press release on June 2.

These changes to our service reflect changes in the production of laboratory-grown diamonds. Most diamonds entering the market fall into a very narrow range of color and clarity. Therefore, it is no longer appropriate for GIA to use the terms developed to describe the broad range of color and clarity found in natural diamonds to describe the quality of a manufactured product.

The GIA Laboratory-Grown Diamond Quality Assessment will use descriptive terms rather than the GIA-developed nomenclature for natural diamonds. The laboratory-grown diamonds will be described as ‘Premium’ or ‘Standard’ based on an overall assessment of their clarity, color and cut.

Laboratory-grown diamonds that meet all the following criteria will be classified as ‘Premium.’

Clarity – Very, Very Slightly included and higher
Color – D
Polish, symmetry - Excellent
Cut grade – Excellent (round brilliant cut diamonds only)
Laboratory-grown diamonds that meet any combination of the ‘Premium’ criteria and the following criteria will be classified as ‘Standard.’

Clarity – Very Slightly included
Color – E-to-J
Polish – Very Good
Symmetry – Very Good (or Good for fancy shapes only)
Cut grade – Very Good (round brilliant cut diamonds only)
Any diamond that does not meet all the minimum criteria for ‘Standard’ will not receive a GIA assessment.

The fee for GIA Laboratory-Grown Diamond Quality Assessment is US$15 per carat, with a minimum of fee of US$15. Submissions that do not meet the minimum criteria for assessment will be charged a US$5 evaluation fee. The minimum size for submission is 0.15 carats. Each submitted stone’s girdle will be laser inscribed with the term “Laboratory-Grown” and the GIA quality assessment number.  A printed document with the assessment results will be returned with each laboratory-grown diamond.
 
Thanks for sharing Gary. Out of curiosity how do the GIA LGD report fees compare with IGIs? I tried to find the pricing info my on the IGI website to no avail. It appears that you can't get a fee schedule without filling out a submission form.

Good question. I can't remember what the GIA was charging, but I am sure it was about 3 times that much.
Given that $15 per carat is around 18% to 30% of the wholesale cost pre carat - the GIA will still not get much business.
The IGI has allowed larger manufacturers to do their own in house grading with the IGI apparently auditing and providing reports. That is not as bad as it may sound since they sell B2B. Most large natural businesses grading is more accurate and provide more information than the GIA does anyway.
 
Good job running the ball into your opponent's endzone to give them the game winning points, GIA!

You're assuming that IGI and GIA have the same "gravitas" ... personally i think GIA should have just gone the HRD route and decided not to bother grading synthetics...

A fair call FB! DJW that would be like not taking the penalty kick?
 
Further proof GIA is set on making itself irrelevant.
Instead of giving consumers what they want, they are set on forcing on them what GIA wants.

Actually Karl - on one platform 40% of LGD rounds are D Flawless to VVS2.
So the GIA may actually have an excellent strategy!

I agree...and what I meant by my earlier reply is GIA needs to be very worried that IGI's approach of B2B in-house grading may (and probably will) start to take hold of the natural diamond segment.
I think even GCAL saw that two years ago with their merger into SARINE.

In House ?...no Conflict of interest there.... :) But seriously for an under $1k purchase LGD it doesn't really matter what the color and clarity grades are.. you can see with your eyes - but for $$$ Natural it's critical to have an independent 3rd party grading since so much of the price is driving by those values.... it's also critical to have 3rd party confirming that the diamond is natural origin and whether or not it has been color/clarity enhanced.... It's funny.... If i see a colorless high clarity Natural with an IGI certificate i assume something's wrong / they are hidden something ~ otherwise would have gone with GIA.....
 
In House ?...
Its a fact that many of the diamonds that long time PSers have and love were purchased by the vendor based on in house grading/imaging. Then sent to AGSL for the consumers benefit by the vendor.
Whats changed is that most everything is sold b2b with the grading report already these days because of the rise of the drop shippers.

I totally agree and don't like in-house grading (even if it's 3rd party lab oversight) because the risks of cheating/gaming the system more than cutters already do to cut and proportion a diamond for max carat weight while knowing how much slop they can get away with to still pop a GIA 3X...but money talks, especially post-pandemic with global inflation raising prices significantly for everything along the chain from surveying, sampling, permitting, digging/mining equipment and labor, storage and transport of rough, cutting and polishing, grading, supplier inventory, distribution/shipping, and all the way to retail aspects of inventory, insurance, advertising, wages/commission, and any other overhead expenses. There are profits getting sought out in every one of those steps to grow and perpetuate business at all levels from raw materials to manufacturing/crafting to the retail level while also combating rising prices to keep enough paying consumers coming in the door.
 
Sample of the upcoming GIA grading report for human grown diamonds?

There's a disclaimer on every GIA report, regardless of the origin of the diamond that was graded...nothing new at all.

i was referring to the disclaimer that stone was a synthetic... Did GIA really need to add the FTC definition reference ? Seems GIA is going above and beyond to differentiate LGD's from Diamonds...... Count the words..

Man Made Diamond - Laboratory Grown (#1) - Synthetic - Maker Created - Laboratory Grown (#2) ... Laboratory Grown (#3)

So when the to be wearer gets their LGD e ring and is looking at the GIA report how's that going to play ??? ooh a Premium Synthetic Diamond !!!
I just don't see anyone wanting to sell a LGD with that report

Well then I guess retailers won't be selling diamonds with the upcoming GIA LGD reports if it's going to impact LGD buyers to the degree that you're alluding to, huh?
IGI and GCAL must be dancing in the streets to that news!

It is illegal to call a diamond anything other than Synthetic in some nations. So the GIA is butt covering.
