Is there any Zakah on Diamonds?
Question:
Is there any Zakah on Diamonds that are used for beautification and wearing?
Answer:
There is no Zakah on Diamonds that are for beautification and wearing.However, if the diamonds are for buisness(i.e., buying and selling), Az-Zakah must be paid on them.The same applies to pearls.In reference to gold and silver, Az-Zakah must be paid on them if they reach the minimum amount required,even if they are only for wearing according to the most correct opinion of the scholars.
