How to read a GIA Diamond Grading Report

Published by:


A diamond certificate is a blueprint of a diamond’s exact quality characteristics and is vital in assuring its quality and proof of your diamond’s identity.

Every Diamonds 27 diamond is accompanied by an original diamond grading certificate from the GIA (Gemological Institute of America) – the world’s foremost authority on diamonds. The GIA Grading Report contains information on the diamond’s shape, cut, colour and carat weight. It may also include a plotting diagram that clearly shows a diamond’s inclusions, proportions and finish.

When buying diamonds online, make sure that you purchase from a trusted source and ensure that the diamond is certified by an international diamond grading laboratory.

What is Diamond Clarity and how it affects the value of a diamond.

Published by:


When we speak of a diamond’s clarity, we are referring to the presence of identifying characteristics on (blemishes) and within (inclusions) the stone. If you think about the incredible amount of pressure it takes to create a diamond and the fact that natural diamonds are not grown in a sterile laboratory, it’s no surprise that most diamonds have flaws.

The formation of a diamond is not a gentle process. Most diamonds are born in extreme circumstances from primeval carbon deep in the earth’s mantle at about 500,000 to 2 million feet below the surface. They are then shot up to the surface at supersonic speeds by eruptions inside the earth. These volcanoes normally are very small, but the magma originates much deeper, which is what enables the diamonds to be extracted and carried up through the earth. The extreme heat and pressure that diamonds undergo during their ascent can cause unique “birthmarks” that affect their clarity. These are referred to as inclusions when they are internal or blemishes when they appear on the diamond’s surface.

The independent grading report that comes with every diamond we sell shows a diagram indicating the characteristics of your diamond, including any inclusions or blemishes your diamond may have and where they appear. The most important thing to remember when it comes to clarity is that a diamond’s inclusions and blemishes should not be noticeable to the naked eye, nor should they be so excessive that they affect the diamond’s durability.

Diamonds are graded for clarity under 10x loupe magnification. We grade a diamond’s clarity according to International Grading System. The international clarity scale has a range of 11 grades that run from flawless (FL) to obvious inclusions (I3). A diamond that is higher up on the Clarity Scale will be more brilliant — and with all other characteristics being equal, more valuable — because it doesn’t have inclusions and/or blemishes that impede its ability to refract and reflect light. In other words, the lower the scale of the clarity the diamond is the less value would have.

James Allen Diamonds

Published by:

Diamond Clarity Chart

You might lately have heard quite a lot about James Allen Diamonds because they are one of the top selling diamond online vendors.

I have made several experiences with James Allen and felt like I want to share my experience with you!

James Allen 360 Degree Video Technology

One of the first things that comes to mind when thinking about James Allen is the fact that they have introduced the video display technology when it comes to buying diamonds.

They were the very first company ever to really go for it!

And in fact this has huge advantages when it comes to examing the diamond color and diamond clarity.

In fact it is a huge disadvantage to buy  a diamond blindly.

In its review of James Allen diamonds diamond expert Sebastian describes how many advantages it has to view the diamond before buying it.

In fact, many people would never buy diamonds on the internet because they think they have to view the diamond personally before buying it. While in fact, this is not necessary it is definitely necessary to view the diamond before buying it.

This can easily be done online.

I also think that it is pretty surprising that one can still find so many people shopping at places like Blue Nile where one is obviously shopping blindly.

With that  being said, I think one should simply have a look at what James Allen itself has to say regarding the entire issue:

Why is James Allen so good for choosing a great clarity grade?

What it really comes down to is the fact that you can simply see every diamond in great detail before buying it!

Thus, you can even choose SI1 or SI2 diamond clarity grades which is a huge advantage. If you don’t have the ability to see the diamond you will have to stick with those diamond clarity grades which are guaranteed to be eye clean.

As you surely know: These are particularly the clarity grades between up to VS2.

Any diamond that has either been graded by GIA or AGS can basically be considered eye clean. It  hardly ever happens that a diamond graded by one of these two labs that is a VS2 clarity grade or better ever has a visible inclusion.

So, this is something that is really good!

But, to make a good bargain on a diamond you should basically buy a SI1 or SI2 diamond. te reason why  these diamonds can get you such a great deal is the fact that they are much cheaper than say VS1 or VS2 diamonds. And of course much cheaper than VVS1 or VVS2 diamonds anyway.

SI1 and SI2 diamonds however are not always necessarily eye clean. But and this is the big BUT: Sometimes they are and sometimes they are not.

So how do you know which ones are eye clean and which ones are not?

Quite easily: You have to look closely at them before buying and this is exactly where James Allen’s diamond display technolgy is coming into play again!

Diamond Clarity Chart

By being able to weed out the SI1 and SI2 diamonds that are not eye clean you can actually find SI1 and SI2 diamonds that ARE in fact eye clean!

What about James Allen’s customer service?

Regarding James Allen’s customer service there have already been some very positive reviews on Pricescope.

Out of my own experience with them I can only say the following: I think it is great that their customer service is 24/7 and that you can actually talk to real certified gemologists.

There are for instance people on the chat that are real GIA graduate gemologists. This is basically the highest title anybody can hope to attain in the diamond industry!

It requires a lot of hard work to obtain a GIA graduate gemologist. In fact, it even requires a time investment of around 6months of full time studies to become a proper GIA GG., as people like to call the title in full.

Thus, James Allen’s customer staff was always very well capable of answering all my questions I had.

This is pretty extraordinary as I dug really deep and asked some really difficult question about the diamond azimuth shift and stuff like that.

It is really great to be advised by someone who really knows what he is doing.

Final Verdict on James Allen

Giving my final verdict i really think that James Allen is a wonderful place to buy  a diamond.

To get more details on the ins and outs of James Allen go and check out Your Diamond Teacher which is a great resource on the diamond 4Cs.

One of the big possibilities I realized at James Allen is the fact that in rare cases you might even get an eye clean I1 diamond! Yes, you read correctly: Sometimes there are even eye clean I1 diamonds. Granted, they are really rare but they do exist!

In such a case you will have to keep on searching for quite a long time! But if you have the patience to do that, I am utterly confident that you will be able to make a really great deal.

I hope you liked my review and you will hear from me very soon!

GIA and AGS grading practices

Published by:

GIA Gemological Institute of America

GIA Gemological Institute of America

You will most likely have stumbled upon GIA – The Gemological Institute of America when looking at different gemstones such as sapphires or diamonds.

Of course, there are also other reputable grading institutes such as AGS which is the American Gemological Society. In general it can be said that GIA and AGS are on the same level. They are both very reliable and consistent in their grading practices.

Now, there are differences though between GIA and AGS as far as grading practices are concerned. This is just what I will get into more details in a moment!

What are the differences between GIA and AGS?

Basically both GIA and AGS use the same system to grade gemstones.

In terms of diamonds they grade the diamond cut, diamond color, diamond.

Thus, they operate on the exactly same basis. However, there are certain differences that no one really knows about.

I want to dive into these differences with you today!

So, there have been quite some discussons about GIA vs AGS.

I basically think that GIA is grading slightly stricter in terms of color and that AGS is grading stricter in terms of the diamond cut!

AGS tries to give the impression of being more sophisticated than GIA and in fact it is! But only in certain ways that are not that easy to explain!

The fact remains however that all big diamond vendors tend to send their diamonds to either GIA or AGS. It does not seem to make all too much difference!

So, in the end you should go with whatever diamond grading lab you like best!

This video for instance describes perfectly well the GIA grading practice for diamonds.

It gives you a good idea how GIA is actually grading its diamonds.

Cheers!
