E 16萬，F 17萬。2隻都係si 的，但肉眼看不出。
I c. In that case, if have to choose one of them, I will pick 1. 3EX is important to have "fire". Beside, SI is no need to match with N. (ps. cutting VG, normally cuz if cut this stone to EX, it will be less then 2Carats. )

3 EX绝对值得重視過螢光反應,MB除了在長波紫外線下有反應外,对鑽石的影響其實不大,反而cut只有VG,对鑽石的亮度(Brilliance)和火彩(fire)一定有所折扣
