Yes tough. (I should be so lucky that is is my tough choice

)
I am either going back to store today or tomorrow (we got snow so may wait) SA gave me 3 more diamond options.
Tried on (pictured above): .18 ct FVS2
19 EVVS1 $2050
.29 IVS1 $2280
.25 FVS1 $2420
Looking at prices/size etc the .29 intrigues me with size / price compared to others. I assume between .18/.19 compared to .29 would be a little noticeable???
SA mentioned to get really high quality color/clarity not necessary with pendant as you cannot see that closely. I have diamond stud earrings that are I color, IF/VVS1 clarity and they sure sparkle.
