Any comparative thoughts among these?

[novice_buyer]

I have narrowed my search down to 3 stones and was looking for some PS advice on which one to go for. they are all in the same neighborhood in cost, but there some differences i am trying to bear in mind.

1) HCA of 1.1

2) HCA of 1.4

im still confused on why #2 is more $ than #1 given #1 is larger. im also have difficulty guessing which will be a more brilliant stone and how to best compare WF to DCD descriptions.

thanks for any help.

ask dcd for ideal-scope images and compare them that way.
by the numbers all 3 look nice.
by the regular photo all look nice.
Get the IS images :}
