Nigella is an Andesite stone with a strong and durable structure that is extremely resistant to abrasion. It’s economically advantageous because it does not fade, lasts for many years and does not require maintenance costs. The stone is ideal for wall coverings, flooring, sidewalks, ramps, and stair steps. It’s also used in outdoor environments; parquet applications, window sills, urban furniture, fireplaces, Turkish baths, and monumental works.
