Kosa Silk is obtained from an Indian silkworm Antheraea mylitta and is a variety of Tussar Silk. It is known for its sturdiness and is preferred to pure silk in the state of Chhattisgarh. Kosa Silk is drawn out of cocoons which are specially grown on specific trees known as Arjun, Saja, and Sal. The two very beautiful places in Chattisgarh namely, Korba and Champa are known for producing high-quality Kosa Silk. The Devangan Community are the original proponents of products made from Kosa Silk. They hail from Bilaspur, Raigarh, Korba, and Champa towns of Chhattisgarh and are largely dedicated to the fabrication of Kosa Silk. The Kosa Silk produced in "Champa" is treated as the best silk all over the world. Kosa Silk Saree is considered ideal and auspicious to be worn to weddings, religious ceremonies, and other ceremonies. The heritage of Chhatisgarh is cherished by women across the nation by draping in the Kosa Silk Sarees.
