The Ancient Egyptians imported cobalt, mined in central Africa, to provide that deep, lustrous blue to ceramics, and it has been in great demand ever since - there will be a lithium-ion battery in your mobile phone or electric car that also includes cobalt.
But this image - generated by digital microscope - is a new, different and stunningly beautiful image: cobalt in colour, but agate in mineral terms.
It's rich, banded pattern certainly makes for a gorgeous image - and amazing that agate can reproduce the colour of cobalt, yet is a completely different mineral.
