I think you mean "Piano Black" which is just a name (think of paint colour swatches with ridiculous names made up by the paint companies).
Vantablack isnt a 'shade' of black. It is a patented man-made coating process created using nanotubes.
Vantablack is composed of a forest of vertical tubes "grown" on a substrate using a modified chemical vapor deposition process. When light strikes Vantablack, instead of bouncing off, it becomes trapped and is continually deflected amongst the tubes, eventually becoming absorbed and dissipating into heat.
And there is a new patented cabon nanotech coating which absorbs even more light than Vantablack.

On further inspection I dont think the ring was photoshopped. It could be high quality Black Onyx or even coated using Vantablack. McAfee could certainly afford to get a vantablack coated ring.
