David,

I've been admiring this (unfortunately, sold) ring and was curious, what type of cushion is the center stone? (Item #R1870)

Thanks!

Goodness that is a gorgeous ring & stone!! 

R3265 has some of the same qualities - brilliant sparkly crushed ice. 

Thanks so much David (and everyone else as well)!! And I second ah2bqat's request!

Great Question guys!
I never actually took note of the specific differences, with regards to how GIA classifies them till recently- I still use visual inspection as the first and last word when selecting.
Both  Cushion Modified Brilliant and Cushion Brilliant can be gorgeous stones. Many Fancy Colors are the modified variety.
The differences have to do with facet pattern.
Unfortunately we don't have the GIA report for the stone Ruby pointed out- the cutter is so large, they actually throw away the I1 reports in some cases.
We will order a duplicate- but checking on the GIA site shows that one is a Cushion Modified Brilliant. Here's a GIA plot for a Cushion Modified Brilliant.

The top is the same- but the bottom main facets are different between the Cushion Modified and Cushion Brilliant

Here's R2894- a Cushion Brilliant



The GIA report



Notice that the bottom is divided into four main groups

In the chart on the post above this,  the one on the left is an 8 Main Cushion

You're welcome clgwli!
Truth is, the way we buy diamonds, it's generally not necessary for me to distinguish things according to those parameters.
IOW- you look at it and can easily see if you love it or not.

For comparison here's an 8 Main Cushion Brilliant

I'm a huge fan of the Daussi cushions, I love the slightly unusual, antique-ish feel to the cut. 8 main appeals to me a lot.

Have to say though, the brilliant cushions are just beautiful too. I think they look very different and I'd be hard pushed to choose between them. I see them as different cuts and I'd like one of each (naturally). 

IOW=In Other Words

I look for diamonds much like you do David.  If my eye likes, I want.  I'm really  not so hung up on namings of cuts.

Well Daussi cuts are a whole other ball game, but it's more of a style to me (like saying antique cushion cut) than it is a label since I know they vary so much.

I can't decide what I like most of these.  I really like an antique look with the open culet.  But I also am starting to appreciate the modern cushions as well.  My eyes are looking for a pendant so right now I think I am looking for more spakles 

Wow. So many great options in a cushion cut & so many reasons to love each!! Thanks for the education David!!

I think David had something like that in the office recently, but it was a bracelet (of course sans pendant, but the marquise could always be organised as the "centrepiece")

The best I can do is a very lame little pencil sketch, photographed and posted (ideally under someone else's name haha) .

I'll see if I can do that tomorrow, if you like.
