Is zakat payable on the gold and silver jewelry that a woman owns?

A woman’s jewelry is not zakatable. Zakat is obligatory on a woman's dowry if it meets the following conditions:
- It is paid in cash and is in the woman's possession.
- It has reached nisab [minimum sum upon which zakat is due. Nisab equals 85 grams of 21 carat gold according to market price].
- It is in surplus of her basic needs.
- It has been in her possession for one full lunar year.
And God the Almighty knows best.
