Super ideal cut
the GIA cert shows Excellence so i presume its SIC
I doubt my other half is okay with lab grown
Really a dilemma...
Bigger size vs bling bling...
You mistaken already.
Excellent is just excellent.
Super Ideal Cut is a terminology given out by JannPaul (and potentially other jewellery shop).
JannPaul's super ideal cut is stricter than just triple Excellent.
Meaning to say, JannPaul will "discard"/"disregard" certain GIA Triple Excellent diamonds as it doesn't fit their "Super Ideal Cut" criteria.
Of course, some other jewellery might consider "Triple Excellent" as a their own form of "Super Ideal Cut", but this cannot be compared with JannPaul's standard.
Analogy:
In O Levels, to get A1 is means 75 marks and above. Parent A may consider A1 as his "Super Smart Student" standard, while Parent B (JannPaul) will say only marks above 90 are considered "Super Smart Student".
So basically a student with 79 marks will be considered "Super Smart Student" by Parent A, but JannPaul will reject student A as he failed JannPaul's "Super Smart Student" criteria. What is true though, is that based on O level marking scheme, both are "A1" students.
GIA Triple Excellent cuts are freaking easy to find, it doesn't mean it's SIC. For example, if you search BlueNile's website, you can easily find 0.5c Triple Excellent, F color, VS1 clarity for S$1900.

But take a deeper look, it has a "Very Strong Blue" florescence, and the proportion (Depth% of 59.9% and Table % of 62.0%) isn't that great.
So this kind of diamond would be rejected by JannPaul.
Now we take a look at another BlueNile's diamond, same thing. 0.51c, Triple Excellent, F Color, VS1 Clarity, is going for S$3,284. It still has Faint Florescence. I don't have the ASET scope, no H&A scope, no HCA score, so it's hard to tell whether it's good or not. Depth of 62.4% and Table of 56.0%.

Again, that does not mean that the S$3,284 diamond will fit into JannPaul's SIC criteria. If JannPaul only considers Depth % of 61-62%, and Table % of 54%-57%, means this S$3,284 will immediately be disregarded because it crossed JannPaul's Depth criteria. But guess what, BlueNile ownself say that this diamond is their "Astor Ideal" diamonds.
BUT i have to stress ah, I can't remember what is JannPaul's SIC criteria for their proportions. It could jolly well be Table of 54-57% and Depth of 61-62.5%, which then means that the BlueNile diamond could POTENTIALLY be considered a "SIC" diamond by JannPaul IFFFFFFFF it passes other JannPaul's criteria testing as well. JannPaul does quite a fair bit of "QC" to filter out diamonds for their "Super Ideal Cut" diamonds, so it isn't just about the Triple Excellent, or just the diamond proportions.
Edited again:
Might just want to take a look at this video, showcasing that 3 diamonds with the same specs, have very different "bling" to it. You can't just look at Triple Excellent diamonds and think they're all Super Ideal Cuts.
I'm not an employee nor do i have any stake in JannPaul.
