The correct answer is option 3- Hallmark.
The standardized mark on jewelry is Hallmark.
Hallmark: This is a certification mark stamped on precious metal jewelry (such as gold, silver, and platinum) to indicate its purity and authenticity. In many countries, including India, hallmarks are regulated by standards to ensure that the jewelry meets specific quality criteria. In India, the Bureau of Indian Standards (BIS) is responsible for the hallmarking of precious metals.
