128-facet cut. 10mm large beads. 50cm long. Approximately 50g in weight. It has a very gorgeous feel. The 128-facet cut is the most labor-intensive, making it high-end. I directly imported the materials from overseas and assembled it myself, allowing me to offer it at this bargain price. Genuine terahertz feels surprisingly light the moment you hold it. It seems there are also fakes made by surface-treating hematite. Made with 0.5mm thick wire, it's unlikely to break under normal circumstances. Beads are placed between the stones to prevent them from scratching each other. Stainless steel fittings are used, so those with metal allergies can rest assured. 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. Compared to the similar stone hematite, it is very light, so this terahertz is recommended for those who are concerned about heavy stones.
