Mangalsutras, also known as Thaalis, are unique pieces of gold jewellery in India that symbolize the bond between a man and a woman. Traditionally, it is given to the bride by her groom on their wedding day as a sign of his eternal love and commitment. The Mangalsutra is usually made from gold, diamonds, or other precious stones that adorn it. It is considered a sign of respect for the woman's family and is worn by her throughout her marriage as a reminder of her husband's promises.
