Terahertz BraceletTerahertz Terahertz is a man made stone (not naturally occurring) created from silica that vibrates at the terahertz frequency range the same frequency band between infrared and microwave radiation. Its considered a high energy healing stone, especially popular in Japan, known as the stone of life energy. Terahertz stone, an artificial silicon based material, is believed to offer benefits due to its high oscillating frequency and thermal conductivity,
