Cleansing pen for gemstones and diamonds 1,5ml has delicate microfibres that contain special polymers. Thanks to that, they’re ideal for cleaning jewellery with precious stones and diamonds as well as platinum and gold jewellery. Polymers will take care of filling up small capillary scratches on jewellery, so they will easily clean your piece of jewellery as well as bring back its brilliance. Take the blue pen cap off, dip the brush in water and turn the silver screw around until blue liquid appears in the brush. Then keep spreading it over the jewellery piece in circular moves until you create foam. Wash the jewellery piece with water and dry it using a soft cloth.
