Which diamond would you choose?

2. 1.40 ct E VVS2 $1310 (the image looks less symmetrical than #1. Will it impact sparkle and brilliance? )

3. 1.51 ct E VVS2 $1698 (does it worth the $600 price jump from #1?)

All 3 diamonds are from Whiteflash, and their pendant chain looks "dull/ not shiny". Does it look better to have a shinier or more understated chain for a diamond pendant?

Thank you so much for your time and thoughts!!
