All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
Zakaah is not due on diamonds and jewelry that are used as ornaments of a woman. All the Muslim scholars are agreed upon this fact. Ibn Qudaamah wrote in his book al-Mughni: “There is no Zakaah on jewelry of woman since no scholars believe that.”
On the other hand, are the ornaments of gold and silver subject to Zakaah or not? Muslim scholars have different opinions. According to the majority of Muslim scholars, Zakaah is not due on golden and silver ornaments. So, you are not obliged to pay the Zakaah on ornaments regardless of their cost.
Moreover, if the income of your husband is not sufficient to satisfy your family needs, such as housing, food, clothes, and other expenditures, then he is eligible to receive Zakaah from others. It is also permissible for your husband to take Zakaah even if you are rich to spend on himself and on his family members. He is not considered rich if his wife is rich since she is not responsible to spend on her husband.

Allah knows best.
