for 0.46 super ideal, D.. VVS2 - $3300 exclude settings
0.54 solasfera , G, VS1 $4500 exclude settings
will prefer a 0.46 solasfera but they do not have. but super ideal still look very sparky and blink too.
Undecided man.
In my opinion it is really a matter of preference which look you like better, a 57 facets or a 91 facets stone? If I remember correctly, for solasfera you can up 1 colour grade, ie your G colour solasfera will be like a F colour for a round brilliant. And then which is more important to you, the size of the diamond or the clarity? Are you able to tell a 0.008 difference in size visually? Unless you really want to be both mind clean and eye clean, then go for VVS2 otherwise a VS1 stone is the way to go.
My 2cents worth.
