Abstract Thursday - Fools' Rock?

I hope this is abstract enough to qualify for Abstract Thursday: for once I've decided to upload a minimally-adulterated photo for the challenge. All I've done on the computer is a focus stack in Photoshop and a tweak of "clarity" enhancement in Lightroom.

This is a piece of rock containing pieces of Fools' Gold; I love the mix of colours and highlights. It's actually one of the rocks I've been photographing for our niece's collection (see here).

Thank you once more to youoregon1 for looking after the Abstract Thursday challenge.
