Buying gold jewelry on the condition that it be shown to the family

Question:
Is it permissible for me to buy something from gold jewelry on the condition that it is shown to the family, or on the condition that if it suits them, I keep it, and if not, I return it to the seller and take back the price?

Answer:
This is not permissible, because this is exchanging gold for gold or for currency, which is considered currency exchange (sarf). Therefore, the exchange of possession must take place in the meeting. However, you may take it on the understanding that you have not bought it; you take it to show it to your family. If they are pleased, you buy it; if they are not pleased, you return it to him. There is no harm in that. But if you buy it and say, "I have the option to show it to my family," this is not permissible. This is not permissible because the sale has been completed, and it is not permissible to separate without the exchange of possession.
