Do you see anything that says “cushion modified brilliant” on that certificate?  That is typically similar to the crushed ice look.

 Btw, beautiful ring!  I have a cushion cut as well and I’m still obsessed and stare at it all of the time!

Fancy cut diamonds are not given a cut grade.

Pretty ring! I also have a cushion cut, though it’s a true brilliant cut. Since getting it I have become a cushion nerd 😂

PP is right, there are no cut grades for cushion cuts or ideal proportions, it’s very much up to personal taste. Based on your photo and diamond plot, you have a cushion modified cut which is known as giving off a “crushed ice” look. Modified cuts are extremely common (making up about 97% of cushions on the market) compared to cushion brilliant cuts (which reflect light similar to round brilliants and face up slightly larger due to cut).

You can figure out if your cushion faces up average in size by plugging in your measurements on diamdb and it should say “this diamond looks it’s weight”. You can also figure out your Length Width ratio by dividing the longer side measurement by the shorter side measurement.

 You do not grade cushions based on measurementts. The cut is evaluated by its light performance, and there are tools to do this like an ASET,  which uses different colors to mark areas of light return.

AGS grades cushion cuts.  I have a antique cut cushion from Victor Canera that is AGS 0 which is ideal.  Of course a lot of diamonds are not graded with AGS and you have to look at light performance/light leakage to see if you have a well cut diamond.
