Question about diamond resale

[Rockdiamond]

To correct my prior post
“Fire” as described here on PS as the rainbow - prismatic effect when facets align properly is a far more quantifiable aspect as opposed to “sparkle” or life.

This!
Somehow it got translated that "Ideal Cut" is objectively better. Period.
Except, judging the beauty of a diamond is subjective. And it always will be.

Even the words "shine" and "fire"...completely subjective.
Yet, the facts and figures, scientific assessment is much easier to latch onto.
From the very beginning of this discussion almost 20 years ago, I strongly object to the use of the word "Ideal".
Can anyone see the difference by eye between EX and VG symmetry? It's not possible for the human eye to distinguish.
But add 2mm? That's very easy to see.

The point is that your existing diamond can be gorgeous ( subjectively)- and still get knocked with "good" cut grade by GIA

I am so sorry for my late response. I was very encouraged by your response and it got me to appreciate even more what I already came to chose after looking at stones every week for a year. Thank you
