Jewels only show their real beauty after polishing. At that point they become luxury items.
For the polishing of precious metals the abrasion needs to be as low as possible in order to limit the waste of precious material. Menzerna polished stainless steel watch cases and bracelets stand out because of their deep mirror finish, which even under the microscope shows no micro scratches or polishing marks.
Menzerna solid pastes and slide finishing products for jewellery applications create gems of lasting value.
