I had to face issues at the bangalore international airport, not for the newly purchased gold but for the old ones which i was wearing.

The customs held me and wanted me to pay a duty of 16K for the 6 gold bangles which I was wearing, I was informed that one should declare the gold being worn or carried at the time of leaving India, if this is not followed, be it whatever new or old we will be held to pay the customs.
Thankfully I could convince the asst commisoner of customs that these were my wedding bangles and i had not bought them from qatar.[ Showed him the pic]. The explained me the rules and left me.
Please be careful while carrying or wearing gold.
