Could you determine if Photons are truly 'mass-less' by colliding two of them inside of a diamond and determining the difference in the mass of the diamond before and after?

No. The diamond would absorb the energy of the photon and the mass of the diamond would increase due to the mass-energy of the photon. I.e. that energy increases the mass of the diamond.
