They have Proof of gold given to you too ? HOW CAN SHE SAY SOME GOLD IS WITH YOU THEN.
If they say its stridhan, then you do not know where she kept all that gold,
As you said she took some of her gold and some left with you, lets say 200grms, that cross some lakhs of rupees, then ask them Income tax receipt too.
If they say gold is given to you or her as dowry then you have to ask judge to read IPC 498a correctly.
GIVING DOWRY ALSO CRIME.
My Advice is to file RTI and ask for the Proofs of Evidence, IO has and submitted to court on her FIR
