Sanghvi jewellery mall, the first one here to be certified by the International Gemological Institute, will be opened in Vizag by cine star Sneha, informed Mr Suresh Jain, a partner of the firm. He further said the IGIs mobile lab had certified the jewellery and the customer could be sure of getting his, or her, moneys worth. He said Rs 7 crore had been invested on the mall. The mall would provide the customers "quality products, unique designs and excellent service," he added. Ms Marissa Martis, Head of the IGIs mobile lab, said the IGI lab had been set up in Mumbai and to meet the requirements of jewellers all over the country the mobile lab with the technicians was being used. "We charge Rs 400 per carat and jewellery will have to be judged on 14 parameters. Diamond jewellery will have to be certified on the basis of cut, carat, clarity and colour," she explained.
