GIA Question - clouds

[Bella123]

Hi everyone,

Quick question about GIA reports:

Under the comments section it says "A cloud is not shown" where normally I see "additional clouds not shown." Why would they phrase it differently? Is it something I should run from? This is also an SI2 stone.

The only inclusions/symbols listed are:
Feather
Knot
Crystal
Needle
Natural

Thanks,
Bella

after following this thread, I would run far, far away from that diamond...

Hi Bella, I will try and explain this to you.

When it says " clouds not shown/ cloud is not shown" or " additional clouds not shown" in the comments section of a report, this means they are mentioned for completeness and are not an issue.

If it says for SI clarity grades " clarity grade is based on clouds which are not shown" or clouds are plotted on the clarity map for SI clarity grades and are listed such as cloud, feather, crystal etc, then these might be of consequence if they impact performance. If this is the case, always get an expert to check. The key is if SI grades are based on clouds.

Thank you both for replying so quickly. I will check the other thread, and appreciate the clarification. I have read multiple times that if clouds are the grade maker, to walk away, so I got nervous when the I saw it written differently in the comments section.

Thanks!

Thats the key and even with some SI that do have grade making clouds, they aren''t always an issue but it is something to be aware of.

This comment means exactly what it says, a cloud is not shown. There is only one cloud in the diamond. If there were more than one cloud it would read "clouds are not shown". If a cloud was plotted on the diagram and there were more clouds then the comment would read "additional clouds are not shown". Since the comment does not read "clarity grade is based on a cloud that is not shown" then the cloud is not the grade setter. Likely this diamond has a large diffuse cloud that if plotted would look very bad on the diagram (i.e. it may cover a good portion of the crown), but in reality it is not affecting the clarity at all and may be a VVS1 cloud and is certainly not lower than the clarity grade of SI2.

Good luck.

definitely doesn''t mean automatically walk away - means have a trusted vendor/appraiser check it out and make sure it isn''t a problem. Rather like sb/vsb fluor - most will be lovely, there are a rare few exceptions to watch out for, but still -most will be lovely

I would not necessarily be concerned if the report says "clouds not shown" or "additional clouds not shown" or "a cloud is not shown".
I would also not be concerned about VS or better clarity with any kind of cloud.
But I would probably recject a report that says "clarity grade based on clouds that are not shown" or "clarity grade based on a cloud that is not shown" or if clouds are mentioned first on the list in a SI1 or lower stone.

The above applies to GIA and AGS stones. Other labs I''d treat with even greater caution.

Hi Bella, I will try and explain this to you.

When it says '' clouds not shown/ cloud is not shown'' or '' additional clouds not shown'' in the comments section of a report, this means they are mentioned for completeness and are not an issue.

If it says for SI clarity grades '' clarity grade is based on clouds which are not shown'' or clouds are plotted on the clarity map for SI clarity grades and are listed such as cloud, feather, crystal etc, then these might be of consequence if they impact performance. If this is the case, always get an expert to check. The key is if SI grades are based on clouds.

Please read this carefully and make note of the distinction. The note you see on your cert is the former case.

Evening folks...so on the GIA report if the cloud is the actual SI grade maker how is it phrased? I jut read the replies but still unclear how you interpret that the inclusions plotted are the one the give your stone the SI grad? Sorry having trouble formulating the question.

 

[Dreamer_D]

Under the clarity plot there will be a list of grade making inclusions, they are listed in order of importance. Cloud may appear there and in an SI it should be examined by an expert to make sure it is not a problem.

Under notes/comments, it will sometimes say " clouds not shown/ cloud is not shown" or " additional clouds not shown". This is not a problem as it means they are not contributing to the clarity grade. It can also say " clarity grade is based on clouds which are not shown" . This is a red flag in an SI and means an expert should look at it to make sure it is not affecting the optics. This is the scenerio in the above link that Sparkly Blond provided.

1. check if clouds are the first inclusions listed - they list in order of seriousness, from most to least.
2. If under comments it says "additional cloud(s) not shown" it''s for completeness as PPs have said, and generally not an issue, though if you''re still worried an appraisal never hurts.
3. If under comments or by the plot it says "clarity grade based on cloud(s) not shown" you may have a problem and definitely want to consult an appraiser.

Ok, looking at my cert it shows in this order

crystal
cloud
feather
natural

In the comment section it does say additional clouds are not shown...

On the plot only shows two clarity characteristics.. based on the symbol key shows what I think are clouds one is a vertical line the other is a odd shaped circle with tiny tiny projection sticking out....what would you make out that?

 

[yssie]

can you post the cert?

 

[Tmissy]

Not able to file too large trying to re-size. Shot is very blurry as well low end digital camera at work. Never mind...

Ok so in this case the crystal is the primary grade maker, the cloud is secondary. I like to check if a cloud is the secondary grade maker but there normally isn''t an issue I have found.
