When you see the number 916 stamped on a piece of gold jewellery, it carries a precise meaning: the gold is 91.6% pure — what we commonly call 22 karat. The remaining 8.4% is typically a mix of silver, copper, or zinc, added to give the metal strength and durability.
The BIS (Bureau of Indian Standards) hallmark is your guarantee of this purity. It includes four components: the BIS logo, the purity grade (916), the jeweller's identification mark, and the year of marking. Together, they form an unforgeable certificate of authenticity.
Why 22K and not 24K? Pure 24K gold is too soft for intricate jewellery — it bends and loses shape. By alloying it to 22K, we retain the rich golden colour and high value while gaining the strength needed for detailed craftsmanship.
At Sofiulla Jewellers, every single piece of gold we sell carries the BIS 916 hallmark. It is not just a stamp — it is our promise. When you buy from us, you buy with the confidence that your gold is exactly what we say it is.
