Any advice on Emerald cut options appreciated

[db73]

Hi everyone!

Looking for emerald cut between 1.65-1.8 carats. These are some options I've found so far, and I would really appreciate any help, advice, and honest opinions on what you think is the best option (and maybe what to avoid). I've hyperlinked them below.

These are some options I've found on Whiteflash:

• 1.70 carat, E, VS1 (this one is more affordable which I'd prefer, but is not Precision brand)
• 1.73 carat, D, VS1 (not Precision brand)
• 1.62 carat, E, VS1 (Precision brand)
• 1.74 carat, D, VVS2 (Precision brand)
• 1.65 carat, E, VVS2 (Precision brand)

Is there a benefit to buying a standard lab diamond from Whiteflash's website if it is not one of their branded selection (aka Precision brand)?

These are some options sent to me by a consultant, I'm a bit iffy on some of them:

• 1.4 carat, D, VS1, LW ratio 1.47
• 1.6 carat, E, VS1, LW ratio 1.49
• 1.76 carat, E, VS 1, LW ratio 1.45
• 1.74 carat, E, VVS2, LW ratio 1.45

Any advice or help is greatly appreciated! Thank you!
