The inclusion of diamonds and precious stones in the nisab

Question:
This issue may be obscure to many, O Shaykh. Yes. May Allah bless you. Also, this woman says: I have sets of diamonds and gold set with precious stones. Do I include the diamonds and precious stones in the calculation of the nisab, or what should I do in this situation?

Answer:
Diamonds and precious stones are not included in the nisab because there is no zakah on them; rather, the zakah is on the gold. If the gold reaches twenty mithqals, which is currently equivalent to eighty-two grams, then that is the nisab, and zakah becomes obligatory on it. However, if it is less than that, there is no zakah on it, and the diamonds are not added to it, unless it is prepared for sale. If it is prepared for sale, then it has a different ruling at that time. Yes.
