Is Zakat obligatory on ornamental gold if it reaches the nisab, and if it is obligatory, is it permissible to sell a portion of it to pay Zakat if no money is available, and what if the gold falls below the nisab after selling a portion of it?

Scholars differ regarding the zakat (definition) on women's jewelry intended for adornment. The majority of scholars hold that it is not obligatory, while others maintain that it is obligatory if it reaches the nisab (definition) (minimum threshold) and a hawl (full lunar year) passes. This latter opinion is more cautious and preferable. If zakat becomes obligatory, it can be paid in cash, or from the gold itself, or by selling a portion of it to fulfill the obligation. If the gold falls below the nisab, there is no zakat due on it until it reaches the nisab and a hawl passes.
