Inorganic fibers are synthetic because they are not composed of organic matter, ie, wool, hemp, cotton.
Natural rubber is made from latex which is taken from trees and is widely used in many products to this day. Synthetic rubber is preferable in most applications today due to the fact that it is more durable than natural rubber and the chances of allergic reactions are smaller.
Biomaterials can be classified into two main groups: synthetic and natural biomaterials. The latter exhibit several advantages over the former, such as biocompatibility, inherent biodegradability,
If you are not a jeweler than the best way is to ask for gemological report at GIA, EGL, IGI. Which will confirm the origin of diamond and it's characteristics. For more information on synthetic diamond follow my link below.
Synthetic is not a term used to describe imitation pearls. Synthetic, in the case of gemstones, is completely manmade, and it has to have the same structure, constituents, and chemistry as its natural counterpart. No cultured pearl is completely manmade. There is always human intervention, but the mollusk grows the cultured pearl. Of cultured pearls, only tissue-nucleated and keshis have the same structure, constituents, and chemistry as their natural counterparts, but they result from human intervention. So when the two criteria that determine a synthetic gem are applied, there is no cultured pearl or imitation that meets both. Therefore, no cultured pearl or imitation is a synthetic.

Inorganic fibers are synthetic because they are not composed of organic matter, ie, wool, hemp, cotton.
When polarized white light passes through a synthetic fiber, it typically results in the creation of two perpendicular rays. This phenomenon occurs due to the birefringent properties of the fiber, where the light splits into two components with different polarizations. These two rays travel at different velocities and can exhibit varying refractive indices, leading to distinct paths within the fiber.
The synthetic fiber that fits this description is Tencel, also known as lyocell. Tencel is made from cellulose, which is an organic compound with two -OH groups like alcohol, and acetic acid, which has two -COOH groups. These two components are chemically processed to create the Tencel fiber.
Regenerated and synthetic fibers. Regenerated are processed natural materials. Synthetic made entirely from chemicals.
Spandex is a synthetic fiber. There are different types of Spandex fabric. The two most common is Two-way Spandex and Four-way Spandex.

Rayon is a manufactured regenerated cellulose fiber. Because it is produced from naturally occurring polymers, it is neither a truly synthetic fiber nor a natural fiber; it is a semi-synthetic fiber. Rayon is known by the names viscose rayon and art silk in the textile industry. It usually has a high lustre quality giving it a bright sheen. Some major rayon fiber uses include apparel (e.g. blouses, dresses, jackets, linings, etc.), furnishings (e.g. bedsheets, blankets), industrial uses (e.g. medical surgery products, non-woven products, tire cord) Rayon may be produced with bamboo as a raw material, and the two may be used for similar fabrics (though natural bamboo is not as smooth), rayon is so far removed from bamboo by chemical processing that the two are entirely separate.
