What makes a Diamond look like this?

[musicloveranthony]

Can anybody tell me what makes a Diamond look this way? I have seen it often in emerald cuts. I don’t see it as often in round cut but this is a great example. Is the stone leaking nearly all the light that enters, or does it have a heavy gray tint?

Wow, did you request the cert? I'd guess that it has an overly steep crown with all the leakage going on there. Probably other issues too. It doesn't seem to be returning any light...but it gets an Excellent cut.

No I haven’t seen. That’s a good thought for why

The paddling at the arrowheads indicates a shallower crown. The size of the table reflection - given table diameter - indicates a steeper pavilion. The lower halves are longer which brings mains and lower halves into more angular parity than shorter LGF would yield, and stars aren’t super short… Which is why you see the over-obstruction “stick” through slight tilt.

No leakage. Doesn’t look overly tinted. This stone would sizzle from across a table.

That’s so interesting!! Thank you. I’d love to see it in person next to another stone

Thanks for the explanation @yssie! I'm afraid I don't understand all of it, but paddling at the arrowheads = shallower crown I will remember.
