Here we have our own water treatment kit, which we have in our store available for customers to drink. This kit includes 2 pc of Rose Quartz and 5 pc of shungite (tumbled, rough & elite). You have enough product to purify two containers of water, or all items can be places in a lager container, (preferably glass), placed in the sun for at least an afternoon.
The Shungite from Russia is from an ancient lake bed containing a complex carbon compound that contains Fullerenes, a purification component.
