What cut grade is my cushion diamond?!?!

[RazorbackBelle42]

Finally picked out an engagement ring! When I got home, I realized that the GIA cut grade isn''t listened on the GIA report. (I now realize that''s normal!) But, it got me wondering - how can I tell what cut grade my diamond is? I found some diamond grade calculators online

... but they are all for round brilliant diamonds. Here are the stats on my diamond:

Cushion Brilliant
Measurements: 5.71 x 5.51 x 3.77
Weight: .87 carats
Depth: 68.4%
Table: 58%
Girdle: Medium to Slightly Thick, Faceted
Culet: Slightly Large
Polish: Very Good
Symmetry: Very Good
Clarity: VS1
Color: E
Flourescence: None
Accompanying GIA Report

I just want to make sure that we didn''t get ripped off. I thought all I needed to focus on was the 4 C''s and I thought we did good! But, then when I saw all the other specs on the GIA Report... I realized I know SO LITTLE!

Any help is greatly appreciated!

There isn''t a really reliable cut grade for cushions, you just have to use your eyes.

Ok! So, looking at the specs above, do you see anything I should be concerned with? I just don''t know enough about diamonds to feel secure. I must admit, I was a bit starstruck when looking at diamonds.

There is nothing to be concerned about because there isn't enough information to assess anything really with a cushion. They are all very different. Based on those numbers I can only tell you it could be anything from a dog to a gorgeous stone!

I'm not seeing any red flags with those specs. Many of the cushions that PSrs post from the resident vendors have tables in the mid 50s to low/mid 60s and depths from about 59 - up to high 60s. VG polish and symmetry is nice to have (almost as nice as "Excellent"). The faceted girdle is med to slightly thick which is also nice in that it's not too thin (which might make me worry about chipping risks), nor is it extremely thick (which reduces spread). Color and clarity seem yummy, too. If you look at it and it makes you happy, I say, kick back and just enjoy it!

Sad to say but the information tells absolutely zip about how bright and fiery or how dull and lifeless the stone may appear.

An expert with a knowledge in the variety of appearances of cushions could help were it in their hands. Most fancies are impossible to assess by numbers alone.

Hi Rhino

Totally agree, and we''ve seen lots of your faboo videos that illustrate the wide range of beauties to stinkers you can get with similar specs (not to mention those pesky unreliable facet plots!). But from the OP''s 1st post, it seemed as if she had seen this stone in person liked it (even if she was a bit star struck). Hopefully, she was allowed to view it for fire and brightness in different lighting environments. I guess it''s just a matter of seeing enough to know the difference between the ookie cushions and the pretties.

Hi Pixley,

Right on with your comments.

A good precautionary measure any consumer should take is, if its possible to *see* the different varieties out there and make an intelligent decision. Since numbers and facet patterns have pretty much proven to be unreliable I personally break break em down into categories of appearance. One I've been running into recently is a mix of both crushed ice and chunky with crushed ice under the table and chunky down the crown angles. Not a very consistent look but it is definitely more fiery than the totally crushed ice look which runs across the whole face of the diamond. Some of the more beautiful ones I've seen lately have been cushion modified too. I like those when chunky flashes are predominant.

The OP's stats are at least off to a good start with the table notably less than total depth at least but again, no hard fast rules. Good to hear from you pixley and good to see you've stuck around here.

Kind regards,
