There are instances when GSC tested a client’s jewellery, the purity was lower than what was indicated on hallmark it bears. For example, the hallmark on the jewellery indicates 916, this means the piece of jewellery is supposed to contain at least 91.6% of pure gold. But the authentication result might come out as 88
