Today I tested whether the quartz I mentioned yesterday. Quartz are piezoelectric, but I cannot seem to find the electrical charges, but quartz also produce a light when it is striked by another piece of quartz. This effect is called triboluminence. It worked for the quartz i bought, and the other one i bought last year together with Ryan, so both are real!
I tried to take a video of it but it did not work. The light from the stones were bright, but the camera caught nothing at all.
