The mangal sutra is a traditional necklace worn by married Hindu women in India. It symbolizes marital status and is often made of black beads and gold. The term "mangal" means auspicious, while "sutra" means thread, representing the bond of marriage. During the wedding ceremony, the groom ties the mangal sutra around the bride's neck, signifying their union. This piece of jewelry is not only a cultural symbol but also holds spiritual significance, believed to protect the husband and wife from negative energies. It is often passed down through generations as a cherished heirloom.
