I have been comparing these two pears that I just received. One is a 10x7 (2ct) and the other is a 10x8 (2.5ct). The 2ct is longer and slimmer, more of a traditional pear shape. The 2.5ct is quite chubby, more like a pudgy tear drop shape. They are both extremely sparkly, but the 2.5 sparkles a bit more and has less of a visible bowtie than the smaller one does. I am trying to decide which one to have set in the beautiful platinum setting that I bought here on the forum. They are both beautiful though. Should I go fat or skinny ???? I really like the 2ct because of the shape, but the 2.5ct seems better cut to me. Sigh...what a dilemma, huh?? 2ct on the left, 2.5ct on the right.
