Theories about Atlantis mention the extensive use of crystals by Atlanteans. Crystals varied in slight, colour, and frequencies. Crystals followed harmonic frequencies and could be used with an instrument that looks like a tuning fork. Atlanteans allegedly harnessed the energies of the pyramids, using harmonics linked to crystals. Like we have the Great Pyramid at the center of the planet linked to the grid matrix that creates our reality, so too, did the Atlanteans. Their pyramid allegedly sank to the bottom of the Atlantic Ocean. Atlantean Seed Crystals were allegedly flawless and grown as we grow flowers today.
