Since you guys are strangers...
1.43 carat @ 7.3mm diameter (comparable top-down size of 1.5~ carats).
Si1, eye clean (amazingly minimal blemishes on the GIA chart, I don't know how this only got Si1).
I color
Excellent cut
Excellent polish
Excellent symmetry
$8800~. Setting (the band) is 14k white gold with halo at $700~
Total is $9500. No tax collected. After Discover card cashback, I paid about $8900. Not bad at all.
I color is more noticeable than I thought. The stone has a slight champagne tint if you look closely.
So my budget focused on maximum brilliance (cut) & carat (what girls like), while sacrificing color and clarity. Clarity is ZERO prob as it's eye-clean and it's graded very well for Si1.
It's true that if you spend for higher than Si1 (vs2, vs1, vvs2, vvs1, fl, & if), you're wasting money. But if I had more budget, I would've gotten G or H color. D (highest), E, F are waste of money too, as most jewelers can't even tell.
