Why is this diamond not sparkling as much? Unsure what to do

Re: Why is this diamond not sparkling as much? Unsure what t

SI 3 was explained to me ages ago on 47th st

When you can't see or it's hard to see any inclusions it's SI

If it's dirty in loupe, but still pretty much eye clean it is SI3

So that was 70's almost 40 years ago

Now a lab may have started using it in 90's but any dealer over 50 knows SI3 if they were on 47th or Sansom St

It is a nice stone eye clean pretty much to most people but usually off centered inclusions lots of them in a loupe

So some may say I1 or I2 but to some it is SI3

Granted AGSL may have fleshed out cut grading, kudos to them for that, but if you look at what dealers are pushing the numbers how GIA is the cert being pushed by most dealers and the public is asking for GIA

I got a dealer I know now giving me his GIA books he used to learn to grade, so now I can see exactly how GIA is defining what I've been asking that no one can answer.

If the stones I'm talking back were sent to AGSL they would be 7 or maybe 6.

My question is how is the GIA grading what would be SI3 or 7 clarity from AGSL

What is their bar to move a stone that has hard to find eye inclusions to I when the loupe shows lots of off centered imperfections

AGSL chart shows

SI2/I1 = 7

Now is that not how AGSL defines 7?

SI2 = 6

I1 = 8

So the AGSL chart shows 7 as SI2/I1

And to me that is SI3 and SI3 has been around for longer than I have looked at carbon which is now 40 or so years

SI3 is a legit 'trade' grade and was heavily used when I used to look at carbon

The best advice I can give you is spend more time reading and less time posting. Those GIA books that dealer friend of yours has offered is a good starting place.

Okay you're an ex CG guy, you are now major carbon guy.

So IN YOUR OPINION

A stone is pretty much eye clean, you look for 5 seconds at face or table and see no obvious flaws. So you think SI or better right.

Yet you loupe it and see instantly off table inclusions lots of them, yet they don't easily show to eye.

So is it SI1/SI2 or I1/I2

Once you loupe it of course the inclusions can be seen, but you have seen lots of stones and you didn't see it fast since it's OC near the girdle mostly.

How would YOU grade such a stone?

Once again, if you read the article I referenced for you earlier, many of your questions about clarity grading will be answered. Or at least will enable you to ask better questions.

As an example, diamonds are graded at 10X. They are also assessed with the naked eye to ensure that the grade is balanced, but whether or not a diamond is eye-clean is not the focus of a grader. Eye-clean depends on many factors including the diamonds's size, facet configuration, and the type of inclusions in the diamond. There is often information contained in a report (in addition to the clarity grade) that can give insight into to the nature of the diamond's overall clarity.

As I mentioned earlier in this thread, the 6 ct N-VVS2 was one of the most extraordinary diamonds I have ever seen. Its rich warm buttery color served as an astonishing backdrop to a light show of phenomenal beauty because of its flawless three dimensional precision cutting. It was sold primarily BECAUSE of the beauty of that color to the buyer.

I had my eye on that diamond and am rather heartbroken that it sold. Such a beautiful stone! Sigh. I still like to watch the video of it. I liked the part where you said it made your heart happy!

** I HAVE ANSWERS!** trip today was so, so worth it!

I know what's up! +1 me, -1 me

Do these threads locked down if there's too many replies? I can start a new thread .. I have a few more questions.



Tourmaline- the 6ct?? WOW!

I had a fantasy of trading in my 5ct L diamond and other jewelry toward that diamond, but I wasn't sure if I could handle the color (my L diamond looks white in some lighting, whereas I don't think and N would), and I have ideas about old cut stones, too, as opposed to modern ideal. And then there are times when I totally love my (early brilliant, late transitional) diamond. Now that the 6ct CBI sold, though, .

I have been reading your thread, hoping you'd return the diamond you don't love for the simple reason that you don't love it. To me, it looks like it's hazy because of the clarity. Makes it look dusty or something. And I totally understand wanting SIZE! I compromised on cut and color. I think if I had spent a lot of time on Pricescope before buying it, I might have chosen differently. Now, though, I don't like the idea of going down in size.

cinnamon, I'm sure I'm not the only one who wishes that that ruby, j.d.,had not hijacked your thread (as he has done with many others). Think it would be good to kick off a new post about today's trip -- and include a quick summary of the preceding background, i.e., why you made the trip.

Beauty is in the eyes of the beholder, not in a GIA report and once you start talking the lingo of GIA and graders, you are not looking at the beauty of a stone anymore, IMO.

Couldn't agree more...look at all these beauties...

AGSL is new and it's an offshoot of a project created by the founder of the GIA LAB.

Enough said on AGSL

If you think that AGS is a second tier grading lab then you should buy a bunch of GIA graded stones and send to AGSL for grading.when these stones return from AGSL you can then make a fortune since most AGS 000 cut stones will fetch a higher premium compared to XXX GIA stones of the same grade.

I am honored that I was given the time to bounce my thoughts and hear replies!! Thank you all for helping me make my dreams come true!!!! PS rocks (no pun!)!!!!

I am a 'tangent' girl. I talk in circles and go off on topics! I'm thrilled this conversation has sparked an interest in so many people! Hijack?? I feel I am lucky I was able to get so many opinions! I enjoyed reading all of the trails this thread took THANK YOU!!!!


In short?
H sparkled NO LESS than anything I saw today in my price range (didn't look at VVS2's obviously)
The "H" has a slight haze (SUPER SLIGHT)--or not as clear. Whatever term

Please see my longer description in the new thread if you wish for more details
