  Etched button 2.
This is an ultra high purity vacuum e-beam melted zirconium button that has had its surface etched with acid to reveal the crystal structure. At least, I think it's zirconium: Philip Kapchenko of Kaistar R&D, who sent me the zirconium button described above, only remembers having sent one button in that package, but there were two when I opened it. They look and feel very similar, so I'm assuming this one is also zirconium, but it's possible it's actually something like niobium instead. Or, maybe it's the other way around and this one is zirconium and the one above is niobium.
