Thoughts On Purchasing An Egl Certified Diamond Versus Gia

Recommended Posts

Hi...

 

If a person is purchasing a diamond and has no intentions of ever trading up etc...this is the diamond I will be buried with. Does EGL versus GIA really matter?

 

Seems to me that you can get a nice stone (better color, excellent cut, exc symmetry, exc polish etc...for ALOT less money.

 

What is the real scoop on EGL if you intend on keeping the diamond forever? Is it worth it to pay the premium for GIA?

 

Thanks!

Yes it does matter. The issue is not whether you can get a beautiful EGL-graded diamond; there are plenty of those. The issue is that you are not paying any premium for anything; the idea that GIA-graded diamonds trade at a premium is a complete myth. Why?

 

1. GIA or EGL do not mine, cut or trade diamonds. They grade them. There is no such thing as a "GIA diamond" any more than there is a "Progressive" or "esure" car because of who you choose to insure it; it remains a brand new Rolls Royce or a battered Ford. Similarly the diamond remains - by objective criteria - that colour and that clarity regardless of whether you call it F or I, SI2 or VS1.

 

2. The difference in cost and timing between GIA and EGL, that many unscrupulous vendors mention, is - when it exists - risible. GIA prices and turnaround times are published on the net here http://www.gia.edu/lab-reports-services/fees_payment/lab_fees/index.html and here http://www.gia.edu/lab-reports-services/turnaround-time/index.html At the time of writing, fees for a 1.00-1.49 ct diamond are about $100, and turnaround time is 6-8 days; shipping time and costs are the same independent of which lab is chosen. EGL may be cheaper but it is not free, and they take 2-4 days for grading. So where's the premium? $20 and a week? On a stone that may be in stock for a few months if not a couple of years and costs several thousands? Pull the other one, Mr Vendor.

 

3. Any diamond can be sent to either or both labs for grading. The seller will then choose to market the stone with the report and credentials they think will get the higher price in the market. Would you rather have an I/SI2 when someone can sell you the same stone as an F/VS2? For a modest $300 premium?

 

4. The issue is not just that (normally) EGL is more lenient with its grading, although some times there can be as many as 6 (yes, six) grades of difference in colour or clarity. The real problem is that it is far less consistent than GIA, and thus the same colour that GIA will reliably grade G or H will go from say E to J with EGL, but the buyer has no way other than his/her eyes to decide which is which. It is not just a case of "downgrading" EGL grades by 1 or 2 notches and look at comparables.

 

5. All of this is compounded by the fact that prices in the diamond market are influenced hugely by tiny variations that are often only visible in strictly controlled and far-from-everyday-use conditions. A D-IF will cost you more than double an F-VVS2, but the two will look the same once set, and even an expert will have real problems telling them apart with a loupe, never mind with the unaided eye.

 

At the end of the day, the diamond's characteristics are what they are independent of the piece of paper that comes with the diamond; if you find a diamond that you like at a price that you like, ignore the paper: that's not what you will be looking at day in day out. But if you want to compare it to another diamond, then who issued the paper does matter.

This has really become of interest to me...as I had stated in a previous thread, I was having some additional stones brought in between 1.39 and 1.49.

The list consists of some GIA and some EGL this time.

 

For instance:

 

EGL: Round Brilliant 1.48 EX G SI2 is priced at 6961.55. (I do not have the polish, symmetry or other specs yet)

It has better cut (per EGL and this can be iffy as I understand), the color is two hues better(per EGL), but is smaller, with the same clarity (have no idea the table or other specs yet), and this stone is only about 500 bucks cheaper?

 

Comparably: I have been looking at a GIA : at 7500.00

 

Round Brilliant

Measurements: 7.40-7.47x4.53mm

Carat weight: 1.54 carat

Color Grade: I

Clarity grade: SI2

Cut grade: Very Good

 

Depth: 60.9%

Table: 59.0%

Crown Angle: 35.0

Crown Height: 14.5%

Pavilion Angle: 41.0

Pavilion Depth: 43.0%

Star Length: 55%

Lower Half: 80%

Girdle: Medium to slightly thick, faceted

Culet: None

 

Polish: Good

Symmetry: Very Good

Flourescence: Strong Blue (I know that some are totally against fluorescence of any type)

You are falling into the trap. The two stones are only comparable IF you are sufficiently expert to grade colour and clarity and trust your conclusions - the EGL "G" could easily be a GIA "K". And SI2 could be I1. Both make a big difference to the price, and do does the cut grade.

 

Also, unfortunately, it is one of the quirks of the diamond market that the price per carat will jump at certain key weight points, 1.50 being one of them, and the GIA-graded diamond is over that point while the EGL-graded stone is below.

 

Does this mean the EGL-graded diamond is a bad stone? Not necessarily, but you will need to rely on your knowledge and judgement (or the vendor's honesty) to compare it to others.

 

Here is a photo of a stone that EGL graded "I/SI1". Brought to GIA for regrading, it came out as Q-R, Very Light Brown / SI2.

Does it matter? In terms of the beauty of the diamond, not a jot. In terms of comparability, particularly of price, it matters a lot.

A very wise friend of mine once explained it this way: EGL is a selling tool and GIA is a buying tool. You get what you pay for, but one lab calls it SI2 while the other calls it VS2. We've gone through this repeatedly and have posted a clear explanation of the differences in our education section: http://www.diamondideals.com/education/find/certifications.cfm

The question is this: if you are buying a donkey and farmer A call it a donkey, but farmer B is calling it a horse, are you really buying something for better value by buying from farmer B? In my mind I would be weary of farmer B because if he is calling a donkey a horse, what else is he distorting?

 

Hope this helps.

The real scoop is that the color and clarity probably are not on par with GIA. If you don't mind really knowing what you got, then go ahead and get an EGL stone. But I've seen them off anywhere from 3- 13 grades. So is your price really better or do you have a bogus report?

 

Do we really know the answer to this question, yes we do.

GIA is the standard for color/clarity grading. Because EGL color/clarity grading standards are lax you are paying more money for less diamond. If you're comfortable with this, fine, but you should be aware of this up front.
