Jewellery Hallmarking is necessary to boost the economic growth of the country. In India, gold jewellery plays an important role for gifting purposes in various auspicious occasions like weddings. Hence, the jewellery industry makes a huge revenue because of the substantial amount of buyers. Due to a large consumption, jewellery wholesalers, retailers and even small artisans tend to cheat on their customers. Also, there is a heavy competition, low-profit rates and higher gold rates, which drive these jewellery industry operators to perform adulterations by selling low karat/ low-quality jewelry in high karats to the public.
