Each Art Glass Energized Pyramid has a mirrored base and a door that opens from the top with a little crystal ball. Ancient Egyptians used the pyramids to generate, transmit and transform energy. Pyramids are known to be a great amplifier of thoughts and are considered the most positive talisman on Earth. Each pyramid comes with a multi-lingual information card (English, Spanish, French, German) SYMBOL: Moon glass color influences dreams. Moon glass is a clear textured iridescent glass.
