the mineral change. This is the reason for the vivid colours of the agate, which are deposited in form of layers.
In the image above, the photography shows how the separation of the impurity aggregates change the tonality of the layer colour. This is more or less how an office printer works; using blue, yellow, magenta and black one can print every colour via microscopic dot-dot structures. Moreover, if the diameter of the nanoparticles was to be modified, not only the tonality yet the colour itself could be changed. However, nanoparticles here will remain chained to their place. As amber traps a fly, they have been stuck in an eternal winter.
