Hello everyone. I bought a diamond online. When I got it, I found there are a black inclusion in the diamond that can only been seen not very easily by tools. But the more concerned is that there are feathers in the girdle. I looked many articles online that it is a potential problem against the durability. I am so worried about it. Would someone give me advice that should I return the diamond cuz the feather or durability? Thank you very much.

I think it would help if you posted the report or the details of the report.
 
You bought an SI1 so inclusions are to be expected but if you can't see them without a loupe and the diamond is sparkly etc. to your eyes, I wouldn't worry. Small feather near the girdle shouldn't pose an issue but your vendor can advise you, or whoever sets your stone in a ring.

A one feather on the girdle can be a concern. But you got 4~5 small feathers with only one on the girdle. And we are talking SI1, which should not have durability issues.
 
Its fine.
I dont worry much about feathers unless they extend from a cavity or are near the corner of princess. Any place else a hard enough hit at the right angle is going to do damage, feather or no feather.
In some cases the area around a feather can be stronger because the strain has been released.

Before I bought it, I requested the vendor to help me check the diamond if any black inclusions. And they tell me it hadn’t. I just feel I was cheat by the vendor.

Thank you. I see it has two feathers which are extend from the surface. And the article online just made me feel scared.

I saw some articles that it should not be washed in the ultrasound machine cuz the feathers extend to the surface. Is it correct?
 
Besides, will it be a concern if I want to change the diamond to another ring? Thank you very much.

As long as they do not extend from cavities large enough to be noted on the plot they are fine in the ultrasonic or anywhere else.
Both ER diamonds I got my wifey have feathers and both have been in ultrasonics many times.

I see. Cuz I read some articles online that it said don’t put it to the ultrasonic machine if it had feather reached the surface.
 
Looks fine, anything on the surface is plotted in green, not red. No cavities.

Sorry. I don’t understand very well. Do you mean even though the same inclusion it still has different color?

And I am worried about the feathers (three of them) around the crown and pavilion would cause durability issues.
 
If there is anything on the surface like a cavity or a natural which is a formation on the rough skin of diamond crystal it is plotted in a different color. The feather would then be plotted in red as it is internal even if it comes from the cavity. You have no green so nothing breaks the surface in any significant way and you may use an ultrasonic without any more harm than other diamonds. Which is to say without any harm.

If I understand correctly, do you mean the feather on my diamond doesn’t reach / extend to the surface / facet from the inside? I am al little bit confused since the feathers on the diagram reached/extended to the surface from inside.

If I get it right, then the feathers cause nothing to the durability?

Then I am interesting that how long of a feather will cuase harm to the durability. Cuz articles online are so terrible. :eek-2:

If inside the diamond it's on the plot in red. If it's on the surface it will be marked in green on the plot.
 
No need to worry...this is a typical SI1 stone. A lot of PSers purchase eye-clean SI1 stones for the cost savings. I have 3 SI1s.
They have been through the sonic cleaner more times than I can remember. I think the usual comment on Si1 feathers
is if it made it through the cutting wheel process (where a lot of pressure is applied on feathers and other inclusions) then
it is a "stable" (for lack of a better word) inclusion. In other words, you have no reason to worry.

Yes, some articles blow things way out of proportion. I hope you feel better and can enjoy your Si1 stone! Also, a lot of times
when a vendor says there are no dark inclusions it means looking at it without a loupe because thats not how we see our stones
99.999... percent of the time. If you want a loupe-clean (sometimes referred to as a mind-clean stone) you will need to go up in
clarity to like a VS1.

But again, there should be no issues with the durability of your stone! Enjoy your new stone!

How about the inclusions (feathers) place inside but across/break the surface? Or it won’t happen?

Thank you very much. You assured me a lot. Can I understand that the only difference between SI1 and SI2 is the number of inclusions in the diamonds? Thank you very much.

Might be easier to understand when there's a visual. If it's on the surface it will be a cavity or see inclusions in green as per picture below.

Maybe I can’t explain well enough before.

I would like to say that a feather which inside the diamond but it reaches (break through) the outside of the diamond, maybe it’s too long. If in this situation, the feather is on both the inside and outside. Then what is the color of this feather?
 
I might be wrong, but it sounds like you’re not happy with this diamond. Other PSers replied that it won’t be a problem and you seems like still finding any flaw (not wrong at all, totally understandable). This means you’re OK if its not this one and you can find a better one. I’ll say keep looking =)2

No, it doesnt work that way. There could be less inclusions (maybe only 1) in an SI2 but it is so big that it qualifies as an SI2 and not
an SI1. Some stones have no obvious inclusions but are "foggy" looking and are SI2s.

For example

I bought it and have already mounted on a ring by 3rd party. So if the diamond has risk, I have yo return it and lost the prices of the ring. That’s why I opened the thread and seek help here.

But I am afraid my english is not enough to said what I want to say. And I am afraid I misunderstood the answer. Thus maybe I asked again. Sorry for bothering all of you.

For example

I saw a 1ct, d color, 3ex, none, no comments, SI2 diamond which only had a middle cloud on the table but couldn’t see by naked eye. And it’s brilliant than mine but I just had a glance. And it had 59% table.
 
I am not sure what you want us to say?
Are you unhappy with the stone? Do you want to return it but not risk losing money on the setting?

Also there are different inclusions some are white and some are black. The cut would help, at a 59% table there might be more white light return and they may have some white inclusions? Are you not happy with your diamond and that's why you are comparing with another?

I would consider returning your current diamond in that ring and lose the money because it clearly seems like you are not happy with the stone :)

Got it! Oh, you’re not bothering at all!!! This is what this forum is for!
I think everyone said that your diamond looks good and the feather is OK.

If you were told that the stone was an eye-clean SI1 but you can see the black carbon inclusion without a loupe then you have grounds to ask them for an exchange or refund. The report has expired so I can't see where the inclusions may have been but if it's on the table then it may be annoying to you. To me, going by the plot, I thought the stone was pretty good for SI1. Do you actually have photos of the stone in the setting?

I have a very 'flawed' (I1) 2ct oval that I'm wearing today and I love her! She sparkles so much and I don't notice any inclusions. If you like the stone in real life, don't worry so much about the inclusions. Everyone has assured you that the feathers shouldn't cause any issues.
 
I see. Cuz I read some articles online that it said don’t put it to the ultrasonic machine if it had feather reached the surface.
I put my wifey's er diamonds in a US and both have feathers that reach the surface.
If the diamond was mine I would not hesitate for a second to clean it in an ultrasonic.
There is a lot of garbage on the net by people that claim to be experts.

Thank you all of you. You are so patient to help me.

Unfortunately I have another problem today.
Today I brought my gf with the rings to shop in Cartier and other vendors to shop wedding rings.

I found my diamond had little fire than others. Although it had lot of brightness. Then i also viewed the diamond under the sun. I only can see the brightness but no fire.

Is it possible that a diamond has very high brightness but with low fire?
And the H&A is not very clear. Does it affect the fire also? I feel a little bit sad. Or it is just my wrong Imagination? Thank you very much.
