What is happening now
At present, as per the Bureau of Indian Standard’s (BIS) website, gold hallmarking is allowed for 6 purity categories, namely, 14KT, 18KT, 20KT, 22KT, 23KT and 24KT. Thus, the jeweller does not have to mandatorily hallmark gold jewellery of other purity (say of 21KT or 19KT) before selling it.
