Amethyst

Pyramids:
Pyramids are believed to have mystical properties across cultures. The pyramid is a Tetrahedron and assists in the process of manifestation. There is a contrasting yet harmonious output of energy within a pyramid. The solid base structure much like a cube has a very grounded and stabilised energy, while still allowing energy to directly flow out of the point. Pyramids are also excellent energy amplifiers and connect the energy of the Crown chakra to the root while attuning us with higher dimensional thought process, our Higher selves and Higher beings of light, and aids in spiritual downloads while staying grounded to earth.
Uses:
pyramids are excellent crystal forms to be placed in the centre of a grid, especially if the motive is to ground or stabilise the energy.
Feng Shui; pyramids being energy amplifiers can create a certain effect in your home, depending on the Crystal you choose. For example a rose quartz pyramid in the bedroom can incite feelings of love and harmony, an Amethyst pyramid in your meditation room may aid you in spiritually attuning yourself to higher frequencies, a Fluorite, Shungite, or green Aventurine pyramid at your workstation may help you get rid of the electromagnetic smog, a lepidolite pyramid in your bedroom can aid in a peaceful sleep. Another use in Feng Shui is to give predominance to a certain element in a certain corner of the house. For example If the wealth corner is depleted, it can be enhanced with a Citrine pyramid, or if the fire element in the house is imbalanced or depleted a Carnelian or Citrine pyramid may be placed to balance the energy.
Pyramids can also be used to cleanse and balance chakras by placing them on the chakras or by meditating on or visualising each chakra while holding a pyramid in your hand.
Holding a pyramid allows life force energy to come into the tip of the pyramid and then ground within and stabilise you. Meditating while focusing on the tip of the pyramid aids in manifestations.
