So I was very generously gifted my crystal water flask from my in-laws this Christmas. Inside I have a smoky quartz. I also have a rose quartz. I definitely feel the quality of the water is different having the crystal in the water.  It reminds me of the Japanese Dr Emoto’s water experiment, where he proved that by writing on a piece of paper ‘I love you’ and sticking it on a bottle and on another piece of paper writing ‘I hate you’ and putting on a separate bottle, he then examined the water crystals under the microscope.
