Hi all. My boyfriend and I bought the following diamond today. We both examined it thoroughly (particularly since it''s graded a SI1) and it was difficult to see any inclusions with the loupe. Once I got home I reviewed the GIA certificate again and noticed the comments section that caused me to write this post. It was very beautiful in person, but I am wondering if the below comments are ok and writing for general peace of mind. Would appreciate any and all responses....considering we already bought the diamond. Thanks!!

Here are the specifics:
Round Brilliant

Measurements: 7.16 - 7.19 x 4.46 mm

Carat Weight: 1.40

Color Grade: G

Clarity Grade: SI1

Cut Grade: Excellent

Proportions:

Depth: 62.2 %

Table: 55 %

Crown Angle: 36°

Crown Height: 16.5 %

Pavilion Angle: 40.6°

Pavilion Depth: 43 %

Star length: 50 %

Lower Half: 80 %

Girdle: Thin to Slightly Thick, Faceted

Culet: None

Finish:

Polish: Very Good

Symmetry: Excellent

Fluorescence: None

Comments: Clarity grade is based on clouds that are not shown. Surface graining is not shown.
 
Your stone is fine. Those comments by GIA are practically standard on every report. It looks like a beautiful diamond on paper.....now where are the pics!!!
 
I wasn''t aware those comments were on most reports. I have heard of a SI rating that has been determined because of the clouds in the stone. Supposedly they can make the stone a little "sleepy". I''m no expert though, maybe others will chime in.
 
I see nothing to worry about!! Nighty night!! And post pics for us in the morning!!!!

I thought I read somewhere to look out for "clouds not shown" and since the clarity grade is based on them, I felt the need to raise the question. I really hope it''s ok since I love the stone. Also, would be happy to post pictures after the stone is set and then officially given to me:-)

Well an SI rating is determined by how visible any inclusions are, not just clouds.

Surface graining is expected and irrelevant to the clarity grade of the stone. Same thing with "additional clouds not shown"...basically it just means that they were detectable but not worth marking on the plot. GIA just wants to make sure they covered everything.

Clouds can be bad, especially in SI rated stones. But the clouds that you are wondering about are so minute that GIA didn''t feel the need to mark them on the plot. Now, if there are a whole bunch of clouds actually marked on the plot, I think that could be a problem. But you said that it''s difficult to see any inclusions with a loupe and that you love the stone. It sounds like a winner to me!
 
To clarify, my initial post came from the following comments contained on Pricescope''s clarity section:

"A worrying ''comment'' is "Clouds Not Shown"; a cloud drawn on plots can look so bad that no one would buy the diamond. Clouds are only a problem on SI1 and lower clarity''s if no other inclusion is marked on the plot, i.e. the cloud is the grade maker. Big clouds can dull the diamond. But it is rare for even I1 diamonds to be dulled by inclusions."

Since I examined the stone in person and can attest that it''s not dull whatsoever, I assume that it should be fine???

https://www.pricescope.com/community/threads/ags-cert-comment-additional-clouds-not-shown.65587/

Basically, the clouds are only a (maybe, possibly, could be, small chance) problem in an SI rated stone if the clouds are the grade maker. "Additional clouds not shown" are not the grade makers. It is just GIA noting that they noticed them. If it was a big honkin scary looking cloud (or even a medium or small sized cloud) they would have marked it on the plot.

If you''re having a hard time seeing inclusions with a loupe, I''d say that it sounds like your stone is perfectly fine.
 
Your GIA report says the clouds ARE the the grademaker. "Clarity grade is based on clouds that are not shown" it doesn't say "additional clouds not shown"

On the other hand, DPS, I'm not trying to rain on your parade

, if you love it and you say it's sparkly, then I'm sure it's fine. They just caution you to be careful.

AH HA HA. Aren't you perceptive!!!! lol!!! I totally missed that.
But yeah, I (obviously) agree that the diamond should be fine.

Yep...they are the clarity grade maker, but I examined the stone and it wasn''t dull and in fact very sparkley given its excellent cut grade. I assume that dullness is the only red flag to look out for..
 
Were you able to take the diamond out of store lighting? Does the place you bought it from have a return policy? (In the small chance you missed something?)
If you and your boyfriend both examined it and it was sparkly and beautiful, then it sounds like you made a good choice. I''m sure the cut helped as well.
 
Nope...didn''t take the stone out of the store. We did, however, examine it under a high-powered microscope and saw the clouds under it. But again, could not see anything under the loupe and the naked eye and it was extremely sparkly. Just wondering that if when they say to be careful, they mean to look out for overall dullness???

They do have a return policy, but we both really liked the stone and unless there''s a big red flag I missed, plan to keep it.
 
Is it a pricesope vendor?
 
it''s a local jeweler that my family has gone to for years...the jeweler itself has been around for decades. Very reputable.
 
Yeah, I don''t know for sure, but I''m assuming that if it affected the stone at all you would have been been able to see a difference in transparency in the area were the clouds are. (That''s just from doing a quick search of the archives though.)
But since you obviously weren''t looking for that when you originally saw the diamond, it might not have been obvious to you. I''d look at it again if I were you, or ask you boyfriend to look at it for you.

I hope it''s a good stone though! Have you thought about settings yet?
 
Here I am raining on your parade again. Most diamonds look sparkly, even poorly cut diamonds under the jewelry store lighting. Good thing to have the return policy. Once you take it out of the lighting, you can decide. Did you compare this daimond next to other excellent cuts?
 
Yes and this one was just as, if not more, brilliant than the others. I really don''t believe the clouds made an visible impact and the stone is therefore eye-clean.
 
sounds fine, just looking out for ya!!!

Appreciate all of the feedback. I am probably worrying for no reason considering we would have noticed if the clouds made a noticeable impact. SI1''s can be a really good deal.
 
I would say if you really like the stone and are happy with it appearance; you''ve got a great diamond. I can''t wait to see photos.
 
Thanks, Luckystar! Regarding settings, the reason I was a bit anxious after I got home last night was because the stone is going to be sent out from the jeweler this week to be set by Tacori.
 
Just wanted to thank everyone who replied to my post. We are all set and are moving forward with the stone and it''s currently with Tacori. I promise to send pics once it''s mine! :-)
 
It sounds like you''ve analyzed it pretty well, as has your trusted jeweler. For the record, grade setting SI clouds may or may not hinder performance. Clouds are clusters of pinpoints. As such they vary. If the pinpoints are especially dense in the grade-setting cloud(s) the grader will turn the diamond; those dense enough to impact light performance will often show a ''shimmer.'' An experienced pro who screens his/her inventory would reject such a stone. On the other hand if the cloud(s) are light and very spread out through the diamond they might still set the SI grade but have no impact on light performance. It''s a stone by stone call, to be made with the diamond in-hand.
 
Thanks, John! Sounds like we found one in which there was no impact on light performance. My jeweler could have easily shown me more stones, but I spoke to her again today and she stressed the fact that the clouds make no visible impact and that it''s a beautiful stone. I am really glad I kept an open mind to an SI1 (initially wouldn''t go lower than VS2).
