Maang tikka is a type of jewelry that is traditionally worn by women in India and neighboring countries. It is a long, decorative piece that is worn on the center part of the hairline and dangles down over the forehead. Maang tikka typically consists of a central pendant that is attached to a chain, which is then secured to the hair with bobby pins or similar fasteners. The central pendant can be simple or elaborate, and may feature gems, beads, or other decorative elements. Some common styles of maang tikka include:

1. Traditional style: a simple chain with a pendant that dangles down over the forehead.
2. Jhoomer style: a larger, more elaborate pendant that is suspended from a chain, featuring multiple strands and multiple pendants.
3. Matha Patti style: a maang tikka that consists of a long chain that runs across the forehead and down the hairline, with one or more pendants hanging from the chain.

Maang tikka is typically worn with traditional Indian outfits, such as saris or salwar kameez, and is often considered a symbol of married status in Indian culture. It can be worn for special occasions, such as weddings or religious festivals, or for everyday wear. The design and style of the maang tikka can vary widely, with some styles being more elaborate and ornate, while others are simple and understated.
