Note: Test stone is not included in the item.
JSP Neutralizer Test Solution is not used to test jewelry authenticity. It is designed to check if acid-based cleaners or solutions have been properly neutralized on surfaces like metal or masonry. After rinsing, apply a few drops to the surface. If it changes color, acid residue is still present. If there is no color change, the surface is neutralized. It does not determine if jewelry is real or fake.
