Approximately 25mm crystal pyramid.
Since ancient civilizations, pyramids have been a source of focused energy and power. Pyramids amplify and then tightly focus energy through the apex. A crystal pyramid is a powerful tool that can be used to draw off negative energy and blockage from the environment and to infuse positive energy. A gemstone pyramid is also used to enhance and focus the properties of the stone it is made of. Pyramids attract energy, transform it and release it into their environment. Pyramids can be used to channel, cleanse, and direct energies throughout your home or sacred space. Anywhere where there is a pyramid, energy won't become stagnant. Crystal pyramids are also very powerful center stones for crystal grids.
