Are you going to file wealth tax return of 2012 now?
Anyways one need to file wealth tax return if the net wealth of assessee exceeds ₹30 lakh and he needs to pay tax @1% on such wealth. Net wealth means total assets less any loan if taken.
So you need to get the valuation of your land and then if it's value exceeds 30 lakh then you need to file wealth tax return and as far as jewellery goes you received it as your grandfather died so he transferred you as a will as you are a legal heir so if anyone ask for a proof you just can give a notarized statement that this jewellery is your ancestral jewellery and you are not required to show it now as you are filing return under section 44AD.
Hope you find the information helpful if you do please rate it 5 and provide your valuable feedback for my improvement.
Thank you
