The double-diamond graphic in the logos of Authenticity Enterprises represents the “diamond anvil.”  

As reported in Physical Review Focus, this photo shows a sample of the elemental metal osmium being squeezed under 600,000 atmospheres of pressure on an anvil (two diamonds separated by a thin metal gasket with 

a hole in the center) by Hyunchae Cynn and his colleagues at the Lawrence Livermore National Laboratory in California. The anvil’s hole is filled with osmium powder; argon was added to distribute the pressure evenly. X-ray diffraction patterns show the spacing between osmium atoms in the sample at different pressures. 

The result: Osmio's bulk modulus of 462 GPa means that osmium holds up

to pressure better than any other known substance. It is stiffer even than diamond, whose bulk modulus is a mere 443 GPa.

In addition to the analogy of ultimate resistance to pressure – pressure from the incursion of corruption and crime, in the case of the digital world – the element osmio is the inspiration for the name of Authenticity’s source of governance, The City of Osmio.
