This necklace features a simple yet sophisticated design, combining beads and spheres. Terahertz Necklace - Decoration: Heart-shaped charm - Design: Combination of beads and spheres Terahertz ore is a silvery power stone, similar to Gibeon and Hematite, said to emit a frequency that vibrates approximately one trillion times per second. Terahertz waves are a type of electromagnetic wave with a long wavelength, ranging from 1 trillion Hz to 100 trillion Hz, and a wavelength of 3μm to 1000μm, possessing properties of both light and radio waves. It is attracting attention as a stone that promotes beauty and health by promoting blood flow and relieving stiffness due to its vibrations. According to NASA, these terahertz waves are "transmission wavelengths" that penetrate materials and reach human cells, thus having an activating effect. Research on this stone is currently underway worldwide. Thank you for viewing.
