Can anyone guide me about GST for Jewellers (retailers)

Gst rate on jewellery is 3%
and making of gold jewellery out of gold/scrap supplied by the customer. At present, there was no tax impact on the making of jewellery. Labour or making charges of jewellery were exempt from service tax (similar exemption was also under excise rules ). Under GST no such exemptions exist and making charges will be subject to 18 per cent GST.
