RBC SI2 2ct with Twinning Wisps and Feathers - Cloudy and Durability?

[LC123]

Hi

Currently looking at a round 2ct/F/SI2.

Am concerned there are too many Twinning Wisps that it looks cloudy and may affect light return? The GIA report does say there are additional wisps not shown. Have been told it is eyeclean and inclusions are white.


Are the proportions ok?

Am also concerned the feather is close to the girdle so it will weaken the structure and cause durability issues? How can I tell if the feather has broken through the girdle surface plane? Does the GIA report show that the same feather is seen from the top and bottom view?

The sales person has played down any of my concerns, so do you guys think the feather is a cause for concern or I'm overreacting?

Any advice would be appreciated.

Thanks in advance.

What is the first inclusion listed in the list of inclusions? Is it the feather? Or is it the twinning wisp?

We had a long discussion on PS once and I think it was decided that all feathers reach the surface.

I dont want to download your gia report. Too many issues with getting infected. Can you bring it up
and provide a link to it like this?

Hi! Thanks for your reply
First inclusion is the twinning wisp.

In general the chance of diminished transparency in an Si2 with twinning wisps as the grade setting characteristic is quite high. Additional wisps and graining as mentioned on the report but not plotted, adds to that probability.
If you view the stone be sure to compare it to a similar stone with high clarity. In that way you will be able to visually determine that the tradeoff you are making in clarity is one that you can live with. While certain types of inclusions are difficult to resolve and can therefore be eye-clean, they can cause a diamond to suffer in terms of light performance.

The inclusions will be fine(as long as you are aware of them and accept them). Twinning wisps are really transparent/invisible to the naked eye most of the time. I have one diamond with the same type of inclusions, SI2 again and it is eye-clean.
However, the angles on this diamond are not very complimentary. Most likely, it will still be a pretty diamond, but it is outside of the recommended proportions for optimal performance. It is also a tad deeper which will bother me perosonally as that means loosing some of the diameter. General suggestions for RB proportions:

Table: 53-58
Depth: 60-62.4
Crown angle: 34-35
Pavilion angle: 40.6-40.9

Do you want to give us your budget and we can find other alternatives?

Thank you for your response.... I was afraid of that answer, but it is probably something I can live with, as long as it isn't too milky looking.. do you think it looks milky from the photo? My main concern are the feathers. Have read through most of the threads on PS regarding this and it still makes me a bit uneasy as I don't want to spend all this money only to be unsure of its durability. Thanks for your help

Hi! Does your SI2 have the feathers near the girdle too? Did your prongs hide them? Thinking of getting a 6 prong.
Yes, I agree re the depth and loss of diameter. but think it may be a trade off.
I did the HCA and got Very Good for all and 2.5. Not sure if this counts for nothing - am very new to all this!

I am based in Australia, so my budget is probably no more than AUD23,000 for the diamond.

Thanks for your help

Twinning wisps can be fine but can also cause a snow globe effect called scatter where they scatter the light passing through the diamond.
It can only really be evaluated in person but as "dirty" looking as that diamond is there is a good chance it has it.

I'd far rather have an H VS2 over any color SI2 especially when the inclusions may have a negative effect on the diamond's beauty. Or I'd rather have a smaller F VS2 if F is the desired color.
