No, white sand is generally not artificial.
White sand, particularly the kind found on many stunning beaches worldwide, gets its characteristic light color from the minerals and organic materials it's composed of. A common source for white sand is an abundance of quartz crystal.
According to the reference provided, this type of sand is a product of a natural geological process. This sand is created by erosion. Erosion is the process where natural forces like water currents, wind, and waves break down larger rocks and minerals over vast periods. As the reference states, water currents play a significant role, causing larger rocks to grind against each other and break down into billions of tiny pieces, which form the sand.
Therefore, white sand, like most sand found in natural environments, is a result of the earth's geological processes rather than artificial manufacturing.
