Is the stone real jade or just glass?

FYI (INFO) The jade cools quickly, if you warm it in your hand and then put it on the table and take it back, it will already be cold. Also a tip for checking, it is best to look at the stone through a light source and / or with a magnifying glass. See if there are any fine veins inside. If you can't see anything or if you observe mini bubbles, the stone may be fake. There is a lot of counterfeiting.

Is it a real jade? i dont think so. the answers to this question say "according to research its real," but its not listed as real jafe anywhere, not even on www.lovisbeauty.ch/products/jade-roller If it was real, theyd state that.

Isn't it called Xiuyan jade, in other words NOT real jade?
