Black Star Artificial Marble is a type of engineered stone that is specifically designed for indoor use. It consists of a mixture of crushed natural stone and resin, which provides durability and resistance to moisture and stains. However, it is not recommended for exterior applications in very sunny climates.

Continuous exposure to intense sunlight can cause artificial marble to fade and lose its original color over time. Additionally, the resin used in these materials may not withstand prolonged exposure to UV rays, leading to the discoloration and degradation of the surface finish.

If you are looking for a suitable material for exterior applications in very sunny climates, it is advisable to choose natural stones such as granite or quartzite, which have proven durability and resistance to outdoor conditions. These natural stones can better withstand the effects of UV rays and maintain their color and structural integrity in such climates.
