Si2 Diamond, Feather inclusion, no plot

[Byron03]

Hi all, firstly thank you for all of the information on this site, it has been a huge help in trying to find a good diamond.

I have found one that I think is ticking the boxes, except for one thing - its is Si2 and has feather inclusions. I have viewed this diamond in person and while it is eye clean, I am concerned after reading on this forum, the issues that you can have with feather inclusions not being durable. There is also no plot on the GIA certificate to show where the inclusions are. Ihave attached the GIA certificate - If you could please let me know if you see any issues with this, including the feather inclusions, that would be great. Appreciate your help.

Any feed back would be appreciated. Thank you!

That diamond's angles need an idealscope. If you are working with a vendor with an idealscope, then they will be able to provide you with magnified pics. The lab report is not helpful in deciding if an SI diamond is going to be eyeclean. You need pictures.

If you are not working with a vendor that can provide you with idealscopes and images then you should not be looking at SI diamonds.

Get idealscopes of the below. And ask if all are eyeclean.

If your budget is close to 4,500 then these are the options I would consider:

http://www.jamesallen.com/loose-diamonds/round-cut/0.90-carat-f-color-si2-clarity-sku-329435 Ask if eyeclean. If this one is, then ask if the feathers pose a durability concern.

If you have up to 5k then these might be good options to explore:

f this one is eyeclean (they would be able to tell you if you call and ask) this is a nice stone for your budget and stats: http://www.b2cjewels.com/dd-5130296-0.90-carat-Round-diamond-G-color-VS2-Clarity.aspx?sku=5130296&utm_source=pricescope.com&utm_medium=referral&utm_campaign=pricescope.com

Thanks for the feedback so far! I have seen the diamond in person and cannot see any inclusions, even under the loupe it was hard to detect. Would I be using the ideal scope to test the brilliance etc? Or is there something else I should be looking for when I ask to look through this?

I spoke to the vendor today who has confirmed that the inclusion is on the edge of the stone, but doesn't break the surface and wouldn't affect durability. Do you believe this to be so, or is there a high risk if that is where it is located.

Thank you also for sending through other options, much appreciated, however at this point my partner has not come around to buying online and would prefer to buy something that can be seen in person.

Do the measurements of this diamond look ok otherwise or do you see any issues with it that should be noted? If you do, could you please explain to me so that I can learn and get a better understanding of what I need to look for.

Thanks again!!

Where are you located maybe can see what's located near you.
My usual post to newbies, this should answer most your questions:

The entire purpose of faceting a diamond is to reflect light.
How well or how poorly a diamond does this determines how beautiful it is.
How well a diamond performs is determined by the angles and cutting. This is why we say cut is king.
No other factor: not color, not clarity has as much of an impact on the appearance of a diamond as its cut. An ideal H will out white a poorly cut F. And GIA Ex is not enough.
So how to we ensure that we have the right angles and cutting to get the light performance we want?
https://www.pricescope.com/wiki/diamonds/diamond-cut
Well one method is to start with a GIA Ex, and then apply the HCA to it. YOU DO NOT USE HCA for AGS0 stones.
https://www.pricescope.com/wiki/diamonds/holloway-cut-advisor
The HCA is a rejection tool. Not a selection tool. It uses 4 data points to make a rudimentary call on how the diamond may perform.
If the diamond passes then you know that you are in the right zone in terms of angles for light performance. Under 2 is a pass. Under 2.5-2.1 is a maybe. 2.6 and over is a no. No score 2 and under is better than any other.
Is that enough? Not really.
So what you need is a way to check actual light performance of your actual stone.
That's what an idealscope image does. https://www.pricescope.com/wiki/diamonds/firescope-idealscope
It shows you how and wear your diamond is reflecting light, how well it is going at it, and where you are losing light return. That is why you won't see us recommending Blue Nile, as they do not provide idealscope images for their diamonds. BGD, James Allen, GOG, HPD, ERD and WF do.

I doubt your vendor will have an idealscope. But there might be an appraiser near you that does.

Give us your metro area.

Hi gypsy, thank you for helping me make sense of this process.

I used the HCA tool, and received a score under 2, with a rating of excellent for 3/4 factors and VG for scintillation.

That is unfortunate that the jeweller would be unlikely to have one. Would this be something that the valuation should show?

Do you think that the GIA certificate looks good as a starting base and something to peruse further? Or is there something on there that raises alarms?

I am located in Melbourne, Australia, not the US...

Also. Is a feather inclusion on a SI2 clarity a risky option? If so, what inclusions should I be looking for ideally?
