Yes, silicon can be found in nature. And in great abundance, too, as it is one of the most common elements on earth. It is often found in the form of oxides, and examples of silicon oxides are sand and silicate minerals.
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.
Silicon and oxygen combine to produce silicon dioxide, SiO2, which is found in nature as quartz or sand.
Elements found in nature are referred to natural elements, as opposed to synthetic, which are man made.
Silk is natural, not a man-made polymer. The silk is mainly obtained from the cocoons of the Mulberry Silkworm (Bombyx mori). When the caterpillar forms a pupae, it encases itself in a cocoon of fine silk thread. Before the adult moth emerges, the cocoon is steeped in hot water to kill the developing moth inside. The cocoon is then unravelled and is combined with several other silk threads to produce a strong silk thread that can be used to produce silk fabric.

Synthetic products are man made. Natural products can be found in nature.
Silicon's modern sources mean that where it is found in nature.
Rutherfordium is not found in nature. It is a radioactive synthetic element.
Meitnerium is a synthetic radioactive element. It is not found in nature.
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.
