Help: I discovered inclusion not appeared in the plot

[Natalia]

Hi,

I just purchased 1.24 carat, round brilliant cut stone from online store in Australia. It's Ex Ex Ex, None culet and None Fluoro. F, VVS1, thin to medium girdle (faceted, 3.5%). There is cloud on the edge of the pavilion on the diamond plot at 5 o'clock direction.

When viewed under miscroscope at home (I work as researcher) I discovered what looks like an inclusion/blemish on the upper girdle facet. I looks like the top part of the girdle is chipped. This is located on teh top of the GIA logo.

This inclusion is not in the diamond plot.

This stone has been set and removed from the set of platinum two weeks ago since this jeweller did a bad setting job. So, I was wondering if this damage comes from this setting and removing teh stone from its mounting processes.

I have cleaned it so there is no way this is a residue/dirt on the surface of the stone.

The clarity is VVS1 so I am a bit skeptical of why this inclusion/blemish is not mentioned at all in the certificate.

Hope you guys can help me to understand the following:

- Is this normal for VVS1 to have such inclusion/blemish not mentioned anywhere in the certificate ?
- Is this look like a damage from the setting process?
- Will this incusion cause the stone acceptable to cracks/chips later on?



I tried to get refund and explanation from the jeweller but they have refused it since their job is only to supply the stone as per the certificate. I am losing sleep over this so hopefully you guys can give me your expert opinions.

Thanks heaps, everybody!

Okay so. Clarity is graded at 10x magnification. That's the standard.

Your work microscope is much stronger than 10x. So of course it's going to pick stuff up at greater magnification than is visible under 10x.

The solution to make the cloud go away? Don't look at it under magnification greater than 10x.



Your stone is graded accurately. It's not on the plot because it is not visible under 10x.

Awesome picture quality

Thank GOD I don't have a microscope. I would go nuts.

If that is all you are finding that must be a super clean diamond. Congratulations!

It's a cloud you found?

Great pictures, a lot of fun to look at

 

[Natalia]

I found the cloud. Here it is... Let me know if this is not the cloud shown on the plot...

However, I still don't understand what's the type of inclusion that looks like long chips above the GIA logo (see "Girdle 2" attachment)

 

[Natalia]

Thanks All but I still wanted to know the type of the inclusion I found (highlighted on the additional photos (inclusion 1, inclusion 2, inclusion 3).

They look like a long chips/glue mark (above the GIA logo) + some nicks on girdle and girdle edge. It's not a glue (trust me) as I cleaned the stone thoroughly!

My main concern is that they are visible under 10x according to the local gemologist who told me he had 10+ yrs experience as diamond specialist eventhough I can't find it myself under the loop
Not sure if he is telling me lies...(the gemo can find the GIA number using 10x loupe).

Also, I attach the diamond plot.

I am scared this is a damage caused by the jeweller who did a bad setting job and refunded my money after removing the stone from his platinum setting.

Thank you heaps for all your expert opinions!

Under what magnification were you viewing the diamond/taking these photos (which are amazing btw)?

So, the highlighted area on the pics is cloud? The nicks are visible on 10x according to the local gemo at local jeweller but perhaps he was just trying to sell his diamond/setting instead so his opinion is biased.

 

[Gypsy]

Where are you located?

 

[FancyIntense]

Here are some great pictures of inclusions. I think a few look like yours, but I don't know. Take a look.

Are you absolutely sure you have cleaned the diamond properly ? try and ultrasonic cleaner .

PS that is not the cloud on the photo its something on the surface

 

[treasurehunter]

It does appear to be some sort of abrasion or burn mark or something but as its on the girdle it could be still graded VVS , Ill have to check the GIA lab manual to make sure but how on earth did you take such a good photo……. unbelievable

Hi Part Gypsy,

Under 40x

I took it to the lab and they cleaned it using toluene solution but it's still there.

I used lab miscroscope which can provide magnification up to 130x.

Thanks in advance for checking! I hope this is not something that was caused by my jeweller who has set and remove the stone from the mounting due to bad setting job!

Looking forward to your findings from GIA manual.

Very minor blemishes that are confined within the girdle are not necessarily plotted or mentioned. The very small chips above the GIA logo in the very high mag photo might not have been visible at 10x and therefore would not figure in to the clarity grade or warrant mention on the report. HOWEVER, the lower mag photos seem to show what looks like a fairly obvious abrasion along the top of the girdle. If this feature is visible at 10x, and it appears to be, it would have been plotted and/or mentioned on the cert. So, if it was not there before setting and unsetting, I would say chances are it is the result of a tool mark or other issue created by the jeweler.

The gemologist you are taking it to should be able to determine whether it is an abrasion or some sort of substance that has been resistant to the cleaning you have done so far.

Those looks like marks from the setting process, based on the look and location. That said, it is also viewed under more than 10x magnification and so would make no difference to the GIA clarity grading which is only up to 10x magnification.

 

[Tourmaline]

Yes, it is possible that this happened during setting.

This is true. It would be good to see new pics with the scope dialed back to exactly 10x. But judging how prominent the abrasion (if that is indeed what it is) appears in relation to the size of the characters in the inscription, I would think this feature would be visible at 10x, but that would make all the difference in terms of the report.

Natalia,
Did you examine the diamond with a microscope prior to it being set? It could be this issue was pre-existing.

Natalia,

Texas Leaguer has properly gotten to the crux of the issue. If the inclusion (abrasions?) are not visible at 10X magnification and were not examined by you at 40X before the diamond was set, there is really no way to determine if they have been there all along or whether there was damaged created during the setting process.

As I read comment after comment in this thread it keeps coming back to the one, needed answer - are the inclusions along the girdle visible at 10X or not?

when I picked up the loose stone I can see the cloudy " circles" on the girdle edge and on the facet junction but not the long so called abrasion on the upper girdle facet above the GIA logo under 10x. Also using GIA inscription no viewer magnifier to view the girdle area. Are these circles are indented naturals? Surely GIA would not miss putting that one on the cert as they are really visible at 10x.

The jeweler did a very bad setting job and even supplied one chipped 0.06 ct side stone. What tools used during setting can cause such abrasion anyway?

I am in Australia and now trying to get a refund. I asked the vendor to contact their supplier in US to get GIA internal notes to see if this is iriginated from cutting process.

I am losing sleeps over this. ...

thank u texas lacquer and diamond hawk and everybody else who have commented

 

[chrono]

Natalia,
I am confused. Did you purchase the diamond new and unset or is it a secondhand stone that was previously set?

Purchased it as loose but had it set by the vendor jeweller.

The vendor marked the gia inscription no area on the stone with washable marker...so that its jeweller would not put platinum claws on top of it. The setting was bad so the vendor was happy to give me refund for the setting only.

It's loupeable at 10x but I can't find it..only the gemologist I knew told me he can.

 

[treasurehunter]

The GIA wouldnt have missed something like that I think .
If it was damaged during setting I think there should be some insurance claim that the jeweller should claim you could say that you are going to send it to the GIA and if its not the same grade as when you bought it you will pursue legal action.
Or you could get it re polished which I don't think will lose much weight, or just live with it as you will never see the difference.
Just some thoughts.
