Terahertz is already light, but at 4mm it's even lighter! It weighs just 11g! It's 4mm so you can wear it casually and it's very stylish. Length: approx. 40cm (the clasp has an adjuster so you can adjust the length by about 5cm) Terahertz The secret of terahertz ore is the energy that causes molecular vibrations one trillion times per second. Terahertz waves (tera / 1 trillion hertz waves) emitted from terahertz minerals are electromagnetic waves that are somewhere between "light sources such as far-infrared rays" and "radio waves." Terahertz waves have a frequency between 1 trillion Hz and 100 trillion Hz, and a wavelength between 3 μm and 1,000 μm, possessing the properties of both light and radio waves.
