reverse charge for jewellers - Goods and Services Tax - GST

When an un registered person goes to a jewellery shop for selling the jewellery, the shop owner needs to pay GST under reverse charge on the amount paid to the un registered person. If my understanding is right, once the shop owner pay GST under reverse charge, is he eligible to avail input tax credit of the same? And if YES under which provisions? And if NO under which provisions?
