Although all observables are "natural" by one definition of that term, there is a meaningful difference between phenomena that arise in the absence of technology, i.e. the intervention of intelligent life, and phenomena that arise because of technology.
Artificial aka synthetic things can be divided into two groups: things created by technology that also occur without the use of technology, and things that occur, as far as we know, only because technology exists.
In the first group, we have artificial light i.e. light that is generated by technology, even though the light itself is physically the same as natural light. Artificial diamonds, though distinguishable from diamonds that occur without the intervention of intelligent life, are still the same form of carbon. Synthetic DNA is the same molecule as DNA that was not made by any intelligent agent.
In the second group, we have nylon and similar materials, which are not harvested from tar pits. All of the sources of laser light are made by humans. Plastics occur only because humans occur.
Granted, the lines aren't as bright as I've made them sound here. Glass occurs naturally, but volcanic glass is distinguishable from lead crystal. And, for some reason, paleolithic stone axes are seldom characterized as "artificial." But a distinction doesn't cease to exist merely because it is fuzzy in certain cases.
