Taking ornaments for gold or gold for ornaments?

Is the error in taking the ornaments for gold or gold for the ornaments?

In the Yoga SUtra there is a verse on avidyA (ignorance) that is the first in the list of kleshas (or taints) that color thoughts.

अनित्य अशुचि दु:ख अनात्मसु नित्य शुचि सुख Atma ख्याते: अविद्या ।

Seeing the Eternal in the transient, the pure in the impure, happiness in sadness, and the Self in the non-Self is avidyA or spiritual ignorance.

Import: Taking the ego to be the Self and seeing sense pleasure that is in fact sadness as happiness, taking the ego and body that are impure on account of being composed of the guNas to be the Self, and taking the transient mind experience to be the Eternal Consciousness is avidyA.

This is the inward path or nivRtti and the first stage in jnAna marga (path of Knowledge). But as the mind having seen the Truth emerges outward, it sees the Self in everything. It sees that the body is non-different from the Self, the ego is non-different from the Self etc. This is vijnAna or Realization.

One may say, it goes from 

Atma anAtmasu to anAtma Atme

From seeing the Self in the non-Self to seeing the Self as everything including what was said to be the non-Self.

नेति नेति

to

इति इति

Neti neti to iti iti ! Not this, not this to This, This.

JnAna to vijnAna.

Both gold and ornaments are the same. No difference.
