Is Hajj compulsory or Fardh for a woman who has such an amount of gold that Zakaat becomes Fardh upon her and she can cover Hajj expenses?

In the Name of Allah, the Most Gracious, the Most Merciful.

As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.

You state that you do have sufficient wealth to cover your Hajj expenses; therefore Hajj is obligatory on you. 

However, you would have to be accompanied by a Mahram when making the journey for Hajj.

And Allah Ta’āla Knows Best
