All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.
Dear Sister, you are not obliged to pay Zakah for jewelry, neither now nor for the past years; this is the view of the majority of the scholars.
Ibn Qudaamah said: "There is no Zakah for the jewelry of a woman if she wears it or loans it out; this is the dominant view of the (Hanbali) School. This is narrated from Ibn ‘Umar, Jaabir, Anas, ‘Aa’ishah and Asmaa’ . This is also the view of Al-Qaasim, Ash-Sha‘bi, Qataadah, Muhammad ibn ‘Ali, ‘Amrah, Maalik, Ash-Shaafi‘i, Abu ‘Ubayd, Is-haaq and Abu Thawr. "
For more benefit, please refer to Fataawa 89106and 83665.
If you want to pay Zakah for your jewelry in order to be on the safe side, then you may do so.
Allaah Knows best.
