I have succeeded in making a fine agreement with both Senorita Mercedes and her family at the workshop in Cusco, Peru and with Senorita Angelica. All jewellery are stamped 950 (Sterling Silver). Which means it contains 95% pure silver.
An in order to be quite certain, the jewellery have been acid tested here in Denmark and it is silver all the way through. In South America, they use a somewhat finer kind of silver than the 925 sterling silver used in Europe.
