Gold Jewellery Hallmarking
Our gold jewellery hallmarking service covers all BIS-recognized gold purity standards including 14K (585), 18K (750), 20K (833), 22K (916), 23K (958), and 24K (999). Every article is tested using calibrated XRF spectrometry, and those meeting the declared purity standard are hallmarked with the official BIS mark and assigned a HUID through the BIS portal. We maintain strict adherence to BIS operational guidelines and calibration schedules to ensure every hallmark we apply is backed by accurate, reliable testing.
Standard turnaround is typically within the same working day for routine lots. Larger lots may require additional time.
