Mangalsutra is a traditional piece of jewelry worn by married Hindu women in India. It holds significant cultural and religious symbolism and is considered a sacred thread or necklace that represents the marital status of a woman. The word "mangalsutra" is derived from the Sanskrit words "mangal," which means auspicious or sacred, and "sutra," which means thread or cord.

The mangalsutra is typically made of black beads, gold, and sometimes diamonds. It consists of a chain with a pendant or a combination of small black and gold beads. The design of the mangalsutra may vary depending on regional customs and personal preferences.

The primary purpose of the mangalsutra is to signify the marital bond between a husband and wife. It is an essential part of Hindu wedding ceremonies and is usually tied around the bride's neck by the groom during the wedding rituals. The mangalsutra is believed to be a protective talisman that safeguards the well-being and longevity of the husband. It is also seen as a symbol of the wife's commitment, love, and respect towards her husband.

The black beads in the mangalsutra are believed to have protective and auspicious properties in Hindu culture. They are thought to ward off evil spirits and negative energies. The gold in the mangalsutra symbolizes prosperity, wealth, and good fortune.

In addition to its symbolic meaning, the mangalsutra also holds social and cultural significance.
