Honestly - I'd pass. It scores a 3.9 on the HCA (worth buying if the price is right), and the images back that up. It is leaking under the table and the H&A pattern is not so good.

Hi,
Although I can not comment on any specific diamond, I can make general comments:
It's often said here that 60/60 is a different flavor than Ideal cut- that's a good way to describe the differences.
If you can look in person, it's going to be the only way one can truly appreciate the differences.
Totally broad brush strokes: the classic 60/60 has longer LGF's- producing thinner arrow shafts and more chances for the light to bounce around before it exits the diamond- causing sparkle and scintillation. But you loose a bit of contrast- the hearts and arrows are not visible.

SO- when trying to use ASET/IS to assess this type of diamond, it's sometimes counter-intuitive.
I have seen stones with ASET which showed some leakage in the table, yet looking at the diamond in real life, outside the ASET, there was no deficiency.
Along with super ideal, a well cut 60/60 is a very nice flavor in my opinion.
I hope you can see one in person to decide for yourself.

I like a good 60/60. That's not one. The crown is too low and the pavillion angle is not a favorable one. Pass on that stone.
