CH.yishi Gua Sha Facial Tool - Natural Terahertz Stone for Face to Lift,Hyperthermia or ice therapy,Decrease Puffiness and Tighten

Ok, i will confess that I didn't know anything about natural terahertz stones. From online reserach; "The terahertz stone, an ore produced by extracting silica from sand or quartz was discovered by Japanese scientists a decade ago to have a terahertz vibration frequency which lies between that of microwaves and far infrared light on the electromagnetic spectrum with its frequency ranging from 0.1 to 30THz." Wow, right?As for those interested in the metaphysical/energy aspect: "Terahertz stone is an excellent energy provider tool. This silver gemstone supplies you with a healthy and potent energy flow to be highly productive and efficient while performing tasks or working on goals that are requiring a high brainpower stream."In terms of the 'paw' gua sha, this stone is smartly designed and well crafted. The silvery sheen is highly reflective, the polishing effecting a shiny, glossy and very smooth surface.There is a small 'eye' hole, to allow a lanyard cord attachment. Personally, I would not use the provided lanyard, and store it, as is, in the provided drawstring pouch.The natural terahertz stone gua sha is pristine, with nary a scratch or nick. The contour has very smooth rounded edges. It looks good and feels good in the hand. Whether you subscribe to the energy aspect, or impressed with the vibration aspect, the fact remains that it's a viable gua sha tool.Attached are photos to show real world images of the natural terahertz stone gua sha, with a ruler for size reference. The gua sha actually look much better in real life.At $13, this is a good value for a decent 'paw' gua sha. For a 'paw' gua sha with premium aspects, it's an excellent value.Based on these observations and initial impressions, this gua sha earns a 5+ star rating, with a very high level recommendation. I am very happy to have this gua sha in my collection.

I ordered this because I was intrigued by the bumpy shape. I've tried a similar shape in stone and really liked it better than the traditional smooth edge, unfortunately this didn't live up to that stone tool. I usually prefer stainless steel as it has a heavier hand feel and can't shatter when I accidentally drop it. This tool was very light, and the shape wasn't carved, it was pinched/indented like this is made of a flimsy metal. I would guess maybe aluminum. I looked up Terahertzite mineral and found nothing, as it if doesn't exist, I could only find Terahertzite radiation/wavelengths. So to be honest I have NO idea what it is made of! It is also smaller than traditional gua sha tools which made it uncomfortable to hold in my hand and try to apply pressure to tight muscles with it.Overall this is a hard pass for me and I suggest that it is for everyone else too.

This stone gua sha kit includes a velour bag, a gua sha stone with a little hole at one end for the separate wristlet which you may attach if you like. Recommended.This review represents my opinion, on the date(s) it was written, of a free product from Amazon Vine Program.
