Are these 2ct+ diamonds eye clean and good value?



Q: Are these 2ct+ diamonds eye clean and good value?

 I think I have narrowed my search down to the below two:
2.06 H SI2

2.08 H SI1

Would both of those appear eye clean? How about the twinning wisps - is that something to worry about? They seem to be white and fairly small, even though they go through the table.
In terms of setting, would putting this in platinum cause any issue?
thanks!!

A:Yes, they're eye clean IMO.

Twinning wisps only become a major concern if they encompass more than a few % points of the diamond. As long as they aren't too close to the girdle it's usually fine.
Will look good in platinum.

Q: Thank you!! What do you mean "more than a few % points of the diamond" ? Do you mean specific locations (e.g. girdle) ?

A: Twinning wisps and feathers are breaks in the diamond. If they are too big they threaten the integrity of the stone. If they are near the girdle they risk getting larger if they are subjected to shock.

Could you please provide me with your opinion about this oval cut diamond?

Thank you so much in advance!



A: I like it.

 The inclusion on the table that is evident in the magnified image seems to be a clear crystal so it's not likely to be noticeable. Remember James Allen has a generous no questions asked return policy, but make sure to read the terms and conditions especially the last clause: https://www.jamesallen.com/guarantee/hassle-free-returns/. the cut quality seems to generate a decent amount of fire, which is real nice for an oval. I'd go for it.


Q: Thank you SO MUCH for your reply! It makes me feel a lot better about what I picked!
One last questions if you don't mind...I see that the depth is 66.90%. I think I read online on a guide that for an oval shaped diamond it's recommended a depth of 58-62% and a table of 53-63%. Would the depth of 66.90% make this less sparkly?

A: It depends on other variables such as its length to width ratio. This is one of the reasons grading labs don't want to give fancy cuts a grade of excellent or any other level because there are tiny variables that are very complex to calculate. Generally speaking a deeper cut or a shallower cut will return less light to the eye of the beholder. Since this diamond has no noticeable bowtie effect it appears to be returning light quite efficiently.
