Kalo Shops Maker's Mark

The National Stamping Act of 1906 (USA), amended in 1961, requires that articles made of gold or silver marked for quality must also be trademarked or stamped with the full name of the maker. In other countries, the process of stamping hallmarks and maker’s marks has been going on for much longer and requirements vary from country to country.
