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.
As long as you imitate the opinion of the majority of scholars who state that no Zakat is due on ornaments intended for personal use based on your sheer conviction and not by means of avoiding paying Zakat out, then you are not obliged to give out Zakat for the past period.
However, the amounts of Zakat you previously paid out are, according to the opinion of the majority of scholars, considered charity for which you would be rewarded. The Fatwa we adopt on our website is that paying out Zakat on ornaments intended for personal use is recommended, not obligatory, as a way of maintaining reconciliation among all views.
Allah knows best.
