The council aims to train, skill and enhance 4.07 million people by 2022.
The council will tie-up with the existing training institutes including Gemological Institute of America (GIA) and Indian Gemological Institute (IGI), alongwith setting up of new institutes in major diamond cutting and processing centres, Gems & Jewellery Export Promotion Council (GJEPC) said in a statement here.
An international training institutes such as GIA are now offering internationally recognised Graduate Diamonds (GD) Diploma programme in Mumbai, a major consumer market for gems and jewellery and home to many well-known jewellery brands.
"Changing customer requirements are increasingly creating a need for a more highly skilled workforce," All India Gems & Jewellery Trade Federation Chairman Haresh Soni said.
However, there is a growing gap in skill availability as the skill development process in the fragmented parts of the industry is primarily achieved through an apprenticeship model and on-the-job training.
This leads to longer training time and gaps in the availability of modern jewellery manufacturing and diamond cutting and polishing skills, he said.
