SI1 inclusions - don''t seem to look that bad to me??

[newbie124]

This is the GIA plot of the inclusions for an SI1 stone I found. It doesn''t look to be that bad to me, though. Could there possibly be any issues w/ the fact that the feature is close to the edge? Or have I just happened to luckily stumble upon a relatively clean SI1? There are no additional comments on the report.

Also, this stone has a .08mm difference in the diameter measurements, which seems kind of large to me. However, it got an Excellent grading on symmetry, and the HCA result was also 1.6 (ex-ex-ex-vg). So is this something I shouldn''t stress over too much?

I haven''t seen any images for this stone, so have only been able to go by dimensions and the cert.

Thanks!

while shopping for my upgrade I found several SI1''s I would''ve bought easily. They were mostly eye clean completely to me, and this is in 3 carat weight where it seems like they *might* be easier to find{?}
I definitely buy an SI1.

Hi ringabling,

Yes, I'm also definitely OK with SI1 diamonds that are eyeclean. I was a little nervous about it at first, after seeing all the magnified images. But after seeing some stones in person I realized that you really can't see anything from a "real life" distance, so I'm more comfortable with that now. Not to mention that it saves us a few grand to boot!

For this particular stone, I'm just wondering why it was graded an SI1 as the inclusions don't seem that severe...Not sure if it's just b/c the feather is a little larger than what would qualify for VS2? Just want to make sure I'm not missing anything that would be a bigger cause for concern.

Great news! I also noticed some SI2''s in real life I could not see the inclusions w/out studying it for a long time. Yay for saving money and sharing!

SI2 here! I think it really depends on YOUR definition of eye clean, as this really tends to range. The only thing I would watch for with SIs, or any grade for that matter, are feathers close to the edge. This COULD pose a problem with setting from a durability standpoint, so have it appraised before you buy or within your return window.

I''m very familiar with the feeling of "this is too good to be an SI, what am I missing"? Sometimes you get lucky though. https://www.pricescope.com/community/threads/does-this-look-to-good-to-be-an-si2.73154/

OK, I found a magnified image of the stone on another site. Is it just me or does the GIA cert seem off? The map doesn''t show any inclusion near the table, but from the image photo you can definitely see some inclusions at about the 6:00 position. I also see a feather just off the table around 12:00 and possibly another mark at 3:00.

Now I''m not so sure about this one anymore....How come the image is so off from the inclusion map? I know there''s some subjectivity in the certification process, but if I could spot these w/ my amateur eyes, how come the experts didn''t note it?

Oops, wrong image! Here''s the photo...

And here''s a close up of the inclusion at 6:00

it could be a reflection of the inclusion that you see and not the actual inclusion. when i was looking at a particular diamond, i was able to see some carbon deposits in areas not mapped in the cert but the jeweler said it was just a reflection of another carbon deposit which was plotted on the map.

is this possible?

 

[newbie124]

Hmm...that might be possible. If so, that sounds worse to me b/c even though the inclusion is in one location, you''re seeing it twice!

I''ve asked the vendor to talk to their gemologists to see if the stone is eye clean and if they think the feather might impact the integrity of the stone. Guess I might just have to wait and see what they say. Although I''m always inclined to take their comments w/ a grain of salt since they''re talking about an item that they''re trying to sell, so...

 

[newbie124]

Also, can anyone speak to the .08mm difference in diameter length vs. width? Is that bordering on too much or still OK?

Usually feathers that are positioned in the upper part of the Diamond like the crown or table will be graded automatically SI.
Some exception on extremely small feathers positioned just about vertically to the edge of the crown might get away with a VS2 if there are no other internal inclusions!

As per the plot in this thread..., looks to me as a straight SI unless the feather is not as shown.

In regards to you 0.08 mm. range..., what is the diameter of the Diamond?

 

[ringabling]

it depends on the size of the stone I guess{?}
my specs are 9.92 x 9.85 equalling .07. . . there's zero visible difference this small:

Thanks for chiming in DiaGem! The diameter is 6.93-7.01x4.32

You're right, it looks really clean on paper. Possibly too clean. I would check to see if there are any unshown features, such as feathers or clouds, that could be large enough to give the diamond an SI1 rating. Perhaps also look at the diamond in person. I have read some things on here from the pros about unshown features (usually noted at the bottom of the report).

ETA: Oops I overlooked where you said there were no additional notes on the report. Okay - I got nuthin.
