Ruby Zoisite:

It is an interesting stone for self-realization; it allows us to discover your true self by letting go of the negative influences of those around you, of the conditioning and fears of your past. It thus contributes to the discovery and achievement of your life goals. It can also be used for balancing purposes: it makes it possible to quickly recover a psychic harmony in the event of stress.

On the energy level, it has the ability to transform negative energies into positive energies. It is a stone of the first order in terms of protection and transmutation.
