Answer:
(Fatwa: 1972/435/D=1432)
It is unlawful for your aunty to demand the gold. When the aunty purchased necklace for your mother and handed it to her, then your mother became the owner of it and its price became due on her. Your mother will have to pay its price. If they remember the price or have the receipt, your mother will pay the price accordingly. If they cannot remember exact price or could not get the receipt, then your mother should pay maximum possible price so that there is no doubt in her mind. Your aunty is not allowed to demand necklace or that much gold or its current price.
