Is zakah obligatory on jewelry worn, and what is the amount of the nisab?

Question : The questioner, Umm Ibrahim, says in her question that she recalls she is a woman who has gold jewelry, not a large amount. It consists of four earrings, three necklaces, and three rings. She says she wears some of it constantly, and some of it on special occasions. The question is: what is the amount of zakah on jewelry? Is zakah obligatory on me? Please guide me in this matter.

Answer : The amount of zakah on jewelry is one-quarter of a tenth, meaning two and a half percent. However, the jewelry the woman has must reach the nisab in total. The amount of the nisab is eighty-five grams. If her jewelry reaches this weight, she owes zakah. If her jewelry is less than that, she owes no zakah.
Accordingly, when the time for zakah arrives, which is the completion of the year, she takes it to people of expertise among the goldsmiths or gold traders and asks them first, "How much does this weigh?" If it reaches eighty-five grams, she asks, "What is its value?" If they say its value is such-and-such, she pays out one-quarter of a tenth, i.e., two and a half percent. By doing so, she has performed the zakah and cleared her obligation. Let her ask Allah for acceptance. May Allah make our deeds acceptable to Him. O Allah, amen. May Allah reward you with good.
