Hmm, I like this one a lot.
A beautiful scan to begin with, too.
Lots of texture and patterns.

I did an extra very little something with the border.
In the corners where the red dots are I messed with an actual photo of a red gem to use instead of sticking with the part on the scan.
Think it makes a difference?

And here's the original scan:
