Jet (Black) is a type of lignite, a precursor to coal, known for its deep black color and smooth texture. It is formed from decaying plant material that has undergone a process of compression over millions of years. Jet is often used in jewelry, particularly in Victorian mourning pieces, due to its striking appearance and lightweight nature. In addition to its aesthetic appeal, Jet (Black) has historical significance. It has been used since ancient times for various purposes, including amulets and decorative items. Today, it is still valued for its beauty and is often carved into intricate designs for necklaces, earrings, and other accessories.
