Something odd with that black triangle. It looks photoshopped in.

Compare it to other black sections of the image. It is too perfectly pitch black, with no visible shading or highlights that should be there. Also the sides of the triangle are perfectly straight and don't follow the natural curve of the ring

Here is a different photo of the same ring, but this time both sections are the same pitch black with zero tonal change.

There are image analysis tools that could help. If I was at home would check it myself.

Something is off with the black.
