Chlorine is not found in the nature in his elemental form.
Carbon can certainly be found in nature, but some of its radioactive isotopes are synthetic.
Synthetic fibers are not natural. They are purely man made and can not be found in nature. Many synthetic materials are made by a process of synthesis. Fibers which aren't synthetic can be found in nature.
I have no clue I was asking you.

Chlorine is commonly found in nature, seeing as it is a critical component of table salt, NaCl. It is also often found in our atmosphere in the form of CFC's. However, diatomic chlorine gas, Cl2 is not too abundant, because it is highly reactive.
Synthetic elements are not found in nature but are created in laboratories.
No, synthetic gems are not minerals. Part of the definition of a mineral is that it is found in nature, not created by man.
