"Natural Diamond: TYPE IaAB" - What the heck does this mean?

[CushionRock2012]

Another question! suprise suprise...

EGL CERT says: "Natural Diamond: TYPE IaAB"
I researched high and low on the internet and could not get conclusive information....

Why does EGL list this? I know it has to do with nitrogen pairings inside the actual diamond that determine the TYPE IaAB information... But why is there such little information around the internet regarding this and why does GIA/AGS not list this on their certs?

It leads me to believe that this diamond could have been potentially pressure and heat treated to increase the color grade?

Please experts/gemologists shed some more light on this and let this be a final answer to what seems like not-conclusive info around the net

Re: "Natural Diamond: TYPE IaAB" - What the heck does this m

I hope a pro actually does chime in. I thought it had something to do with the florescent quality that the presence of those atoms (nitrogen and boron?) in the stone and less about whether it was treated or not.

I don't think it's on a GIA or AGS cert because it's not a common trait and they would be able to test to be sure if it's treated or not and if it is would outright say it was treated in their reports.

Ya... but GIA also doesnt have crown height/pavillion depth/graining/or cutlet information either....

And from what I read, I read that "most" gemstones are type IaAB.... but don't know what the heck that really means...

Why is there so little information when there seems to be tons of information regarding every other little stone detail?

Please someone help that knows FOR SURE! I am having a "type IaAB" stone graded at AGS right now and want to make sure it is nothing to be concerned of in case their report comes back with no comments regarding this...

Thanks!

On a dossier they might not have the angles, etc. but on a full report they usually do.

"Type IaAB, in these diamonds nitrogen is present in the A and B aggregate forms as well as in the N3 centers. The N3 centers cause a notable absoroption in the visible region of the spectrum causing pale to intense yellow colors in diamonds. They may have faint to medium florescence."

I found that someone had asked the same question you had, the poster didn't credit who he quoted so I don't know who to credit either. Here is the link...

Another question! suprise suprise...

EGL CERT says: "Natural Diamond: TYPE IaAB"
I researched high and low on the internet and could not get conclusive information....

Why does EGL list this? I know it has to do with nitrogen pairings inside the actual diamond that determine the TYPE IaAB information... But why is there such little information around the internet regarding this and why does GIA/AGS not list this on their certs?

It leads me to believe that this diamond could have been potentially pressure and heat treated to increase the color grade?

Please experts/gemologists shed some more light on this and let this be a final answer to what seems like not-conclusive info around the net

or this from wikipedia....

If you want gemologists to respond- you should maybe contact one or stop in a shop with one employed... There are a handful of appraisers on here to respond but at times it is infrequently.

Re: "Natural Diamond: TYPE IaAB" - What the heck does this m

I don't know why EGL lists it, for the sake of it since they know it maybe
I do know gia/ags would label it irradiated or hpht treated if it was treated anyway

the different types are the different quantities of nitrogen that causes the tinge of color in the diamond,
different types react differently to different hpht techniques(to boost the color in different ways)

so it does not mean that your diamond was treated. if i'm not wrong, type iaab is to be treated to become more yellow(fancy) instead of being more colorless.

Actually, if you would have read my first post :

"I researched high and low on the internet and could not get conclusive information...."

I did research... and I did find exactly what the other poster said they found which is ALSO in my first post:

"Why does EGL list this? I know it has to do with nitrogen pairings inside the actual diamond that determine the TYPE IaAB information... But why is there such little information around the internet regarding this and why does GIA/AGS not list this on their certs?"

Looks like you guys didn't read the first post...

Just was looking for confirmation or MORE details on what I found... Did NOT mean to offend anyone... I just was amazed that after being on a forum for a time period as long as it takes to get 5200 posts, that nobody had ever really gone over this question in detail...

Perhaps in the future, you can think of a more tactful way to express your "amazement". Everyone here, including the experts, tries to help others to the best of their ability. Just because they can't answer your question to your satisfaction doesn't give you the right to rudely dismiss their efforts to help.

Re: "Natural Diamond: TYPE IaAB" - What the heck does this m

If you had bothered to post what you DID find, that would have been helpful. It would have shown that you did try and it would have saved others time finding that link. I'd looked up the info recently but it didn't mean anything to me and I figured that if I could find it, you could, too, and I didn't feel like spending my time looking it up again and posting it for you.

I don't know why you think someone's post count has anything to do with what they do or do not know. If it's something that's obscure and isn't of interest to them, they could have ten kazillion posts and they still won't know. They'll know lots about common things and things that are their passion, but not about everything there is to know.

I consider myself pretty abrupt, abrasive, argumentative, and combative at times, but you've got me beat many times over. I'm surprised anyone is still taking time to reply to you after reading your other thread. People have bent over backwards to try to help you and your responses have been nothing but nasty.

"Natural Diamond: TYPE IaAB" - What the heck does this mean?

I actually did read your initial post and i surmised that you didn't really try all that hard. It took another poster 5 minutes to find what she posted and i posted based in what little that was covered in gemology classes thru GIA.

You seriously need a lesson in tact. If you really want help, maybe someone else who isn't bothered by your combative and obnoxious tone and sanctimonious attitude will care enough to help, but don't count on it. I'm done.

My favorite part of this is, the guy is a total hypocrite. He has the balls to criticize us because we didn't answer his every question perfectly whereas in his other thread 30 posters told him you can't judge cushions by the numbers or his crappy pics and he was still asking-- after 30 posts answered him-- for people to tell him what they thought of the stone based on the numbers and his crappy pics.

HEY BUDDY, in case you missed it in your other thread:

THE CUSHION YOU ARE CONSIDERING IS NOT ONE WE RECOMMEND YOU BUY. It has a visible inclusion and it faces up too small for the carat weight. And you are being overcharged for it. Those two facts ALONE (visible inclusion and spread) trump any so called "excellent" on that certificate of yours that we've told you, repeatedly, is NOT ONE YOU SHOULD RELY ON and should discount the price significantly. Also the fact that your vendor is trying to overcharge you for a crappy stone is a CLUE that you shouldn't continue working with him.

And since you asked, that is the EDUCATED opinion of someone who was for TWENTY THOUSAND freaking posts on this forum.

Move on, find another stone. And please understand, it won't be with OUR help in the future. You've succeeded in alienating an entire FORUM of people with your entitled attitude. Congrats.

geese you guys are harsh... i am def not a troll... you guys get offended easily tho!

I will learn in the future to be more weary of my online tone... I was just frustrated that there wasn't definitive information on IaAB, other than what I originally posted I found.... Sorry...

Anyway- I appreciate all the comments in my other thread... the reason I kept asking was because I felt people were just looking at the fact it was EGL international and not just answering my questions about the numbers until I repeated them...

yes, there are stones that face up bigger... but not many for the same price range... and I am talking cushions here, not round... not much out there in 2 carats...

and yes, I know its not the best stone in the world but I dont want to go any smaller and have yet to find anything similar... the ones people posted werent quite comparable...

but when my AGS comes back on Monday I'll be able to compare apples to apples... and if then I realize I can do way better, than I will move on and consider the $250 wasted but well worth it to know for sure...

thank you for all your help- i say thank you after every post... check my other thread... not "entitled" at all... humble, actually....you guys sure get riled up over nothing...

1. It's WARY not weary.

2. You need a new definition for humble. We are NOT easy offended, you are just very offensive. Yes, I am sure. It's not us. IT'S YOU. If it makes you feel better to think otherwise, okay. But you are in denial buddy.

3. A good independent appraisal would have been more valuable than an AGS anything. And would have run you about 180 bucks at most. And this was suggested to you. Again, repeatedly. Why? Because it would have given you a value to work with and bargain with and your AGS report won't.

4. What is the point in having a 2 carat stone that looks like a 1.7? Is it just for bragging rights that it's a two carat stone? Cause that's just ignorant. Educate your lady about how dimensions and carat weight correlate and have her make an educated choice about which she prefers: size or carat weight, instead of just assuming.

5. Your budget is too small for a 2 carat stone without sacrificing something significant. You would be better off with a stone that weighs less, has a GIA certificate, and faces up similarly, has ASET images and clear pics of the faceting. This, also was suggested to you repeatedly.

6. Why should we keep wasting our time with you? I see no reason.

Gypsy covered that pretty well, I didn't get much "humble" from your posts. We really don't want you to waste time and money on inferior stones and we really are trying to help bit you have to be realistic, and listen when we say that the budget you have is not going to get the specs or lab report that you want in the size you want and obviously stop being so argumentative and tactless because the ones that would be the most helpful to you have been turned off by the language you're using whether a tone is being inferred or not.

Exactly. Just because you say "thank you" a few times doesn't make you humble. Or sincere. It's quite obvious you DID NOT appreciate the help you were given because A) you ignored it and B) kept asking the same question over and over again even AFTER you were given the answer multiple times because you were SURE you knew better. That's arrogant and entitled and obnoxious. And then in this thread you took it even further and attacked Ame who was just trying to help you. If you can't recognize that, you have more problems than we can help you with. You tone and your actions tell the truth more than your false thank you's. We we see that. We're not stupid.

And you still haven't apologized sincerely. Instead you turn it around and make it sound like WE are the ones with the problem. Yeah, that's humble. NOT.
