Using gems to vitalize water is an age-old tradition, dating back to ancient Greece. In 2007, German scientists reinvented this method hygienically and naturally. German scientists have proven that water becomes more alkaline and the oxygen content increases with VitaJuwel gem vials. The tests showed that "with VitaJuwel, drinking water reached a quality level otherwise only found in natural spring water." VitaJuwel is the most hygienic and efficient method to prepare gemwater.
