128-facet cut product. 6mm beads. Length 45cm. Weight approximately 15g. The 128-facet cut is the most labor-intensive, making it a high-end item. I imported the materials directly from overseas and assembled it myself, allowing me to offer it at this affordable price. Genuine terahertz is surprisingly light the moment you hold it. There also seem to be fakes made by processing the surface of hematite. Made with 0.5mm thick wire, it rarely breaks. Beads are placed between the stones to prevent them from scratching each other. Surgical stainless steel fittings (with 316L marking) are used, so those with metal allergies can use it with peace of mind. It won't rust even if you wear it in the bath. When immersed in ice, the ice melts instantly. A stone that emits terahertz waves Terahertz ore is a silvery power stone similar to Gibeon and hematite, and it is said to be a stone that emits a frequency that vibrates approximately one trillion times per second. Terahertz waves are a type of electromagnetic wave, emitting a long wavelength, between 1 trillion Hz and 100 trillion Hz, with a wavelength of 3μm to 1000μm, possessing the properties of both light and radio waves. According to NASA, these terahertz waves are "transmission wavelengths" that penetrate matter and reach human cells, making it a stone currently being researched worldwide. This terahertz is an artificial ore made of silicon and is not a natural stone. It is characterized by being very light compared to the similar stone hematite, so this terahertz is recommended for those who are concerned about heavy stones.
