"Mangalsutra" carries immense importance in a Hindu Wedding as well in lives of Hindu married women. Though basically it is a black and gold beaded necklace with a gold or diamond pendent(shape and size varies from region to region) but it carries much more importance than a mere jewellary item as it reflects the union of the husband and the wife and is a symbol of promise by a husband to his wife that they will always stay together.
With the changing mindset of women and fast development Mangalsutra today comes in handsome range of designs to choose from, but its importance remains unchanged.
