I have read reviews from people who say they really like these stones, that they improve the taste of water and so on and so on. So I decided to buy it and test the product myself. I have a Berkey Imperial filter that produces great tasting water and this is my base water. Before the test, I cooked the stones according to the instructions. I had 4 glasses of water. all from the same batch of Burke filters and all sat all night for about 8 hours of saturation.1 with nothing so I could use that for my base sample.1 with white beads. I did not notice any change in PH. 1 with mineral stone. I noticed a slight increase in PH, maybe 0.5-1 PH1 on both. I saw a 0.5 increase in PH. After doing this test I took the stones and white bullets to work and we have a high tech XRF gun from Thermo Scientific. It's a $30,000 x-ray gun. This is an x-ray gun that, depending on the model you buy, shoots x-rays at metals and/or rocks and provides you with the elements of the material captured. Our weapon is designed for metals, but contains most of the elements of the periodic table, except for a few. The weapon has two sets of filters 1 heavy and 1 light. heavier filter finds heavy elements lighter finds lighter elements. The severe ones are detected in the first 5 seconds of the shot, and the light filter turns on thereafter as long as you keep the shutter button pressed. good and fairly accurate reading. with +/- 2%. Here are my results White ball results (trigger hold 36 seconds): Al: 21% Si: 75% Fe: 0.5% Zn: 0.1% Zr: 1.2% Nb: 0.05% Bi: 1, 1% No traces of copper, magnesium and manganese. Extremely low zinc and iron content. I can't read calcium, sodium and potassium. So that's not to say they don't exist, but from what the gun reads, what it can see, I don't feel comfortable putting these elements in my body. You can raise the pH of the water, but what our XRF gun sees are not beneficial minerals. Mineral results (hold trigger for 35 seconds): Al: 14% Si: 81% Fe: 4% Zr: 0.09% Again, no. copper, magnesium, manganese and zinc. Cannot read calcium, potassium and sodium. If you add up the percentages, you'll find that they don't add up to 100%. This is because the weapon cannot read all the elements in the gems. So this mineral rock may contain calcium, potassium and sodium, but I can guarantee that it contains no traces of copper, magnesium and manganese. Conclusion. These stones are fake and do not work. This is a scam. They work to raise PH, but I wouldn't assume it's about raising healthy, beneficial minerals. Even slight traces of potentially useful minerals as my weapon has absorbed zinc and iron. I personally recommend anyone using these stones to stop. I don't think they are hygienic and safe to eat. I will not use them in my Berkey filter or any other filter system. I hope this review helps and that you make the right decision for your health and stay away from it. I am not a doctor or scientist. I love science and health and am fortunate to have access to amazing equipment. These results are based on my personal experience with the santevia mineral stones I have purchased. Thanks for reading and God bless.
