1.44 SI1 with knot (w/ picture) Your thoughts?

[c87]

Hi all-

I wanted to get your thoughts on this diamond (eye clean):

http://www.gia.edu/cs/Satellite?reportno=1169688893&childpagename=GIA%2FPage%2FReportCheck&pagename=GIA%2FDispatcher&c=Page&cid=1355954554547

My concern is with the knot listed. Should I be worried about location or visibility? Does this have an affect on durability of the diamond. Also, I currently have a G and love the color. Do you think I will be disappointed (relatively) by stepping down to a H?


Also, is it just me or does one of the "arrows" in this picture look a bit off? Not sure if it's a picture issue or a diamond issue.

Thank you!!

I had to laugh, I think this may be the 3rd or 4th various stone you have posted with an inclusion that is of concern. If you research a knot inclusion will give you a very good idea. Any diamond that I would consider and after reviewing, I would contact the vendor and talk to the Gemologists to get their opinion on the size, location, durability, of any inclusions that are of concern, they would be in a much better position to answer that question.

Going from a G to an H will still be very white and really hard to tell any difference in a setting. Yes your picture image arrows are off, could be tilt in picture or not good cut/symmetry.

Thanks, c-k. Yeah, I figured as they are separate stones, a new thread is warranted. I guess I'm more looking for people who have had experience or have diamonds with them.

Alas, can you draw any sort of conclusion on my other question? The funky "arrow" in the picture. Not sure if' it's the angle of the photo or the cut.

EDIT: Just saw your response on the arrow. Perhaps the cutter working with said knot? Either way, I'd hope that that would get the GIA's attention to downgrade symmetry!

The knot is very small and in the pavilion , a knot is a diamond growing inside a diamond , its very small and won't affect nada.

Optical symmetry (hearts and arrows pattern ) is different than the symmetry grade for diamond cutting. GIA and AGS both don't do optical symmetry , google optical symmetry good old good for more info..

What is the HCA score?

 

[c87]

HCA score is 1.2, excellent in all categories.

Just curious, if that picture was all you had to go on (and a solid return policy), would the apparent mis-alignment give you cause for concern?

I do not have a way to get idealscope images, etc.

It looks fine, but it isn't very tight.

 

[c87]

Could this affect light return?

Also, I'm only going to be able to assess this diamond after I order it, so any further guesswork on the picture will help.

are you buying the diamond to view it with a hearts and arrows viewer ? If so you may want to reconsider the diamond if not then there is nothing to worry about .

it is true that diamonds with a H&A pattern are among the top performers, however there is no concrete evidence that the absence of a hearts and arrows pattern will make it have less light performance. It is also possible for a hearts and arrow diamond to show inferior performance

It's not just possible. It's very possible.

Hearts and arrows is patterning. ONLY.

It is not a guarantee of performance. IN ANY WAY SHAPE OR FORM.

Performance and light return are a matter of angles. Not pattern.

Hearts and arrows means precision faceting. That is separate and distinct from light return and performance.

You get ideal light return in MANY MANY stones that are not hearts and arrows. And you can get compromised light return in hearts and arrows stones.


Since you haven't been great about listening to advice to date I'm not convinced there is any point in saying this. BUT-- read this: [URL='https://www.pricescope.com/community/threads/likelihood-of-finding-a-signature-super-ideal-diamond.174235/']https://www.pricescope.com/community/threads/likelihood-of-finding-a-signature-super-ideal-diamond.174235/[/URL]


IF you read that thread, it will hopefully help you understand the issue more.

Im glad we agree on this one

The link that Gypsy posted is great information, really gives insight to Super Ideal vs Ideal diamonds, thanks.

Spoke with a gemologist at the vendor who has yet to see the stone but raised some concern over the knot and it being a pressure sensitive inclusion. Obviously haven't seen the diamond, but just judging the gia report, it doesn't seem like a great problem
