Answer: The workshop must not mix one customer’s gold with that of another; it has to keep each batch separate if the carat differs. If, however, the carat is identical, there is no objection to combining them, for that causes no harm.

Q: Is the workmanship fee required to be paid when the gold is collected, or may it be left as an open account?

A: Immediate payment is not obligatory, for the fee is compensation for labor. If it is paid upon collection, well and good; if not, payment is permissible whenever it is made.

Question Nine: What is your opinion of a situation in which a customer asks for the current gold price, then, once informed, brings out used gold he possesses and sells it, and after receiving the cash proceeds to buy new merchandise?

Answer: There is nothing wrong with this so long as there was no prior agreement or collusion.
