What is 916 hallmark gold?

916 hallmark on gold means what?

916 hallmark gold refers to gold that is 91.6% pure. 91.6% purity is in 22 carat gold. The ‘916’ hallmark is an official stamp, primarily regulated by the Bureau of Indian Standards (BIS) in India. The bureau guarantees both the purity and authenticity of the gold.
The 916 level of purity strikes a crucial balance: it is soft enough to exhibit the premium qualities of gold and hard enough to withstand daily wear, thanks to alloying with other metals like copper or silver.
The 916 hallmark itself serves as a promise to buyers that what they are getting is exactly what is claimed, reducing the risk of fraud or adulteration in jewelry purchases.
