Is zakat obligatory on a wife's gold designated for wear on special occasions, given that a full year has passed, and knowing that the wife has no income and no money from which to pay zakat, and is the husband obliged to pay zakat on her behalf?

Scholars have differed on the ruling concerning jewelry, with the most accurate opinion being that it is not obligatory [to pay zakat on it]. However, paying zakat on it is more cautious, as it avoids disagreement and absolves one's responsibility. It is permissible for a husband to pay zakat on behalf of his wife, provided she is aware of it and he intends to pay it on her behalf.
