Cushion Brilliant or Modified Brilliant

[TahitianMoon]

Hello everyone,

I've learned so much from this forum. You are all amazing in sharing your knowledge of diamonds.

I have an engagement ring that my husband had appraised a few years ago when we got engaged. Unfortunately, I don't think the diamond has a GIA certificate otherwise I think the appraiser would have given me the GIA number on the diamond. I know the 4 C's of the diamond, but the appraiser didn't indicate whether it was a cushion brilliant or cushion modified brilliant - he just wrote "Cushion Diamond". The appraiser is unfortunately out of business so I can't contact him to ask for clarification. He did draw out the plot.

Based on my research online, it isn't really an 8-point main because even though it has 8 points, the placement of the points are different. Is there only one standard plot for an 8-Point Main cushion diamond?

Is this one just a generic cushion brilliant? There is no culet. I looked at all the loose diamonds sold online and their GIA certificates and I have yet to see one with a plot like mine - at least the ones that are currently for sale.

I have included the plot and also a photo of the diamond, but I had to zoom in and sharpen it since it's so difficult taking a photo of it with just my phone so I apologize if this photo isn't helpful at all.

Any information about my diamond would be much appreciated. Thank you.

Do you have any other up-close pictures of your stone? Maybe not as up close as the one you already posted.

BtW...the stone you posted looks like it has 4 mains. I'm wondering if the person who did the appraisal just drew out a
generic cushion. It doesn't look like it matches your stone. Unfortunately, it is hard to tell anything from that picture.
If you've got any others, please post.

Thank you for your response. Well, that is interesting!

Mystery deepens on this stone. I think I may have to take it in for another appraisal. I just didn't pay much attention to the appraisal at the time except for the 4 C's. I've attached a clearer photo of the diamond. I look forward to your feedback.

What is the purpose of your enquiry?
There are at least a dozen facet patterns and almost all of them can work well or really poorly.
Knowing what yours is will require the pavilion side really good clear photos but unless you don't want the diamond any more this would not be a cheap exercise to remove and rest.

Yes, if I had to say I would guess yours is some kind of 4 main. Does not match the generic picture of the cushion he
gave you but as Garry H said above there are tons of different cushion cut patterns.

Thank you for your response. I don't want to sell the diamond, I was just merely curious about the diamond, especially since it appears that the plot drawn on the appraisal report and actual diamond may not match, but it makes sense that without removing the diamond from the setting, it may be a futile exercise.

And GIA and all labs don't often get them right
