At Crystal, the highest quality is paramount. That is why we have examined most colloidal silver suppliers and have them tested by independent laboratories. See the results here.
Crystal colloidal gold has a clear ruby red color. The liquid is clear and not turbid at all. The color can change slightly from light ruby red to dark ruby red to purple with increasing concentration of gold present. At 10 PPM the color is ruby red. See image.
Some things to know about in connection with the prejudices that exist to switch from Glass to PET. It is important to make a difference between ionic silver and colloidal silver if you are going to fill colloidal silver or other colloids in bottles.
It may be that you have recently learned something about a gray-blue skin discoloration after using colloidal silver. Again, this is not a colloidal silver. The cause of what happened is ionic silver. Where skin discoloration has occurred, people have tried to make colloidal silver at home. It is impossible to make real colloidal silver at home.
It is almost unbelievable but you can calculate it yourself. When you distribute 2 liters of Crystal colloidal silver over 1 hectare (10,000 m2), you have 1.1 billion particles of silver per square millimeter (mm2). This incredible number is caused by the small particle size of our product, namely 0.65 nanometers. If the particle size would be 650 nanometers, then in the above example you only had 1 particle per square millimeter (mm2).
