There is no one definitive style of Indian mangalsutra design. Traditional designs tend to be very simple, with a black bead on a thread or chain. However, modern designs can be much more elaborate, with colorful beads and pendants.
One of the most important things to consider when choosing an Indian mangalsutra design is the meaning behind the symbol. Mangalsutras are traditionally worn by married women as a sign of their marital status. The black bead is said to represent Shiva, the god of destruction, and the gold or silver chain is said to represent Shakti, the goddess of power.
Mangalsutras can be made from a variety of materials, including gold, silver, platinum, diamonds, and even glass. Traditional designs tend to be very simple, with a black bead on a thread or chain. However, modern designs can be much more elaborate, with colorful beads and pendants.
