Gold is an element that occurs in nature. Through mining process, gold deposits are obtained and then by refining process, pure gold is extracted.
Man made gold has been attempted by using bombardment techniques against others metals like copper to restructure the atoms arrangement and convert it to gold. This method is very expensive to make gold.
In alchemy, there are instance and notes mentioning how gold can be made by using herbs and metals like silver, iron etc. This is a esoteric subject without any valid proof but might still be a valid one.
Straw is a natural material, typically made from dried grasses such as wheat, rice, or barley. It is a renewable resource that has been used for centuries in various applications, including as a building material, for animal bedding, and as a component in making hats and baskets.
Elastic is a natural material made from rubber, which is harvested from the sap of rubber trees. The process of turning rubber into elastic involves mixing it with other materials to create stretchy properties. So while the manufacturing process involves human intervention, the base material of elastic itself is natural.
Aluminium is an element, it is not synthetic.

Polar fleece is a synthetic fabric made from polyester. It is not a natural material like wool or cotton.
Yes Polyester is a synthetic man made material.
Concrete is a man-made material that is produced by mixing cement with aggregates and water. It is not a natural resource, but rather a construction material that is widely used for building structures.
Fiberglass is man-made material composed of fibers of glass. It is not a natural material, as it is produced through the combination of silica sand, limestone, and other materials heated to high temperatures.
A bridge can be man made or natural. Anatural bridge can be a tree, made of stone, or any natural material and isn't man made.
