actually gold is not a great investment as a brick or jewelry contrary to popular belief and the belief of average Pakis only because of inflation. So in the long run u will probably be losing value. Unfortunately people don't understand that or refuse to believe it. The only good thing about it is that gold will always be valuable even if it's not as it was 10 yes ago. And stones are even a more worse investment than gold. All in all tell the MIL to buy jewelry to wear nor as an investment and in this economy if investments matter than tell her to buy gold stocks or coca cola stocks under the name of her DIL.
