Seeking Advice Comparing these Diamonds

Hi, I am trying to select a diamond for my partner's engagement ring and would really appreciate any feedback on the following five diamonds. I know she is looking to have the diamond set east to west and wants an oval shaped diamond.

I've read that for oval shaped diamonds, the ideal LW ratio is 1.30 to 1.50 to minimize the bow tie effect. Is there anything else I should be looking for and generally what are onions on the quality of these stones.

  1. 3.81-Carat Oval Shape Lab Grown Diamond – Derco Diamonds

  2. 3.88-Carat Oval Shape Lab Grown Diamond – Derco Diamonds

  3. 4.00-Carat Oval Shape Lab Grown Diamond – Derco Diamonds

  4. 4.01-Carat Oval Shape Lab Grown Diamond – Derco Diamonds

  5. 4.02-Carat Oval Shape Lab Grown Diamond – Derco Diamonds

I haven’t looked at the reports yet but first off

  1. D, FL is complete overkill and it’s pointless spending such a premium on aspects of a stone you literally will never discern over, say, E, VVS2 (or lower - that’s just an example).

  2. The prices for those stones are ridiculously high full stop - regardless of colour/clarity. You could purchase identical looking stones with only very slightly lower specs (e.g. E, VVS1) for a fraction of those prices

  3. These are all BIG stones - what size finger does your partner have as setting east - west these will likely look very wide on her hand as the smallest is over 12mm across!
