Peronal gold jewellery transfer in firm's stock

Hi All,

I want to know that if there a jeweller and he wishes to include his wife's and his personel gold into his firm's stock, what is the legal way to include this gold in his firm's stock. As per Indian Law a man can possess upto 300 gm unaccounted jewellery(correct me if I am wrong) and similarly a woman can possess 600 gm. So can this personel jewellery be included into his firm's stock if YES then what is the legal procedure to do so.
