Can a 36.5 CA with 41.0 PA work? GIA RB.

[Yang Kin]

Ok, so there is one particular person who purchased a GIA graded RB with this combo. Anyone has experience looking at this combo compared to a super-ideal RB with tighter proportions? How does it fare in real life, not with scopes? Are the differences - none? subtle? obvious?

Oh, and it has a 63.3% depth. So, yeap, HCA is only 4.7.

I can agree that stones that have proportions that are as strict as any super-ideal vendors can perform pretty similar, despite having near Hearts & Arrows pattern, but I am really curious how the above GIA RB will perform in real life.

My original engagement ring diamond is close...35.5 CA, 41 PA, 63% depth, 60% table. I don't recall the exact HCA (and am unable to look it up now since the they've limited it), but I'm pretty sure it is in the 4-5 range. Mostly white light return and very little fire, but somehow not a disgusting amount of obstruction. No discernible arrows and very little contrast. Definitively a lot more "shine" to it when it is clean, but needs to be cleaned A LOT to look its best (even the tiniest bit of dirt or oil seems to dull it). Of course, under jewelry store lighting it looks pretty impressive LOL I'd say the differences IRL are very obvious when compared to my upgraded diamond (36 CA, 40.6 PA, 61.9% depth, 57% table, HCA of 1.7 if I recall correctly)...it just isn't as lively and doesn't have the same "spark". But by itself and to the average person not educated on diamonds, I'd say it just looks like a run of the mill diamond. Not particularly eye catching and nothing to "oohh and aahh" over, but not complete trash either.

Depending on table size similar to one of these. a 60% table will look worse than a 55 table.

My wife’s first wedding anniversary ring was a GIA XXX T56/D62.8/CA35.5/PA41.2 (HCA 4.2).

Not quite the same realm as the stone you mentioned @Yang Kin

In daylight conditions, there is less fire than her original ER (which is ungraded) and compared with her push present solitaire ring (a BGD Blue), much less fire than that one. A fair amount of white light return (but still nothing like her BGD Blue).

In reduced diffused lighting conditions, it is very dark compared with the BGD Blue which picks up whatever light is around and produces some fire.

It’s only in highly directed spot lighting that the HCA4.2 stone starts looking like her BGD Blue in daylight conditions.
