Garrad's Eernal cut - what do you think?

[HopeDream]

Pure curiosity:

Due to the news of the royal engagement, I decided to see what the signature cut of the royal jeweler looked like.

On their information page I noticed a dark ring around the center of the diamond - is this a fisheye or obstruction?

Any thoughts?

Looks like obstruction to me.

Actually I think the Queen fired them.
