Black Moonstone

Spheres:
Spheres emit their energy from all sides, expanding to an entire room evenly. Their energy has a childlike innocence to them and brings a playful, whimsical element to our lives. Spheres provide an overall stability, harmony, and unity since their energy is very balancing. The circle resembles the circle of life, and brings in life force energy and wholeness.
Uses:
program your sphere with a specific intent to release energy wherever it is placed to aid you in meditating or find solution to a particular problem or healing a certain emotion.
Place a sphere in the centre of a grid to emit the energy or intention gently and evenly.
Spheres can also be used for scrying or crystal gazing. Get yourself in a receptive and meditative state and focus in your question and gaze into the crystal to receive downloads or outlooks into the future.
Massage therapy: Try rolling a sphere where there is pain or tension in the body. Spheres are excellent for releasing pent up energy stuck in the body.
Cleansing. Spheres of Clear quartz, carnelian, or selenite can be used to cleanse the energy of a certain area in the house or other crystals.
Meditation; hold a sphere in each hand during meditation for harmony and connection to life force.
Black Moonstone:
Black moonstone represents the energies of the goddesses of transformation like Hecate or Kali. It energetically aligns with the dark phase or waning phase of the moon when one needs to contemplate, reflect and let go of those people, places, situations and things that cease to do them any good. It is an ideal crystal to access the subconscious mind and rid it off those tormenting emotions and thoughts that creep out of their hiding spots to create occasional upheavals in you and hence aids in shadow work. It therefore helps you see the darker aspects of your own psyche and dispel them gradually so that you may be a better version of yourself. It also bestows upon the user the gift of intuition and is hence an apt stone for divination.
