	Specifically life does not use metals on their own and even barely at all as building blocks. The main exception is Calcium in bones and teeth. But Natrium which is always free floating solvated and just serve electric signalling purposes is not counted here (Same with iron and other transition element metals). The preference of life for nonmetals can be seen by comparing the map of the nonmetals to the map of dietary elements. {{todo\|add illustration}}		Specifically life does not use metals on their own and even barely at all as building blocks.

	In the context of semi advanced to fairly advanced artificial atomically precise nanosystems metals can be used if they are ~~paird~~ with electronegative nonmetals in very very roughly 1:1 ratio. Many common gemstones fall in this category best known is sapphire the oxide of aluminum.		In the context of semi advanced to fairly advanced artificial atomically precise nanosystems metals can be used if they are paired with electronegative nonmetals in very very roughly 1:1 .. 1:2 ratio. Then the bonds become more covalent in character and immobile. Many common gemstones fall in this category best known is sapphire the oxide of aluminum. Most of the gemstones we find in mountains are not synthesized by any lifeforms.
			Advanced atomically precise manufacturing makes accessible not only a super-set of both bio-minerals and mountain-gemstones but also gemstones completely out of nonmetals but in structures that life is not able to generate. The most prominent and commonly known example of such a gemstone out of dietary elements but that life is unable to synthesize is diamond (but there are more).
			Life is probably unable to generate those special gemstones because they can only be mechanosynthesized in practically perfect vacuum and there pretty much certainly exists no continuous evolutionary path toward the necessary advanced atomically precise systems that provide this practically perfect vacuum. It needs us humans to take this step and overcome this complexity barrier.

	The periodic table of elements is probably out of good reason (minimal complexity?) not much bigger than it needs to be to allow the emergence of life in our universe. The minimalistic and general nature of our set of chemical elements allows us to use it like a construction toy in other more straight forward ways than life does.
