Alicia Plata´s Designs are silver .925 (sterling silver)
Sterling silver is an alloy of 92.5 % silver and 7.5% of copper. The sterling silver standard has a minimum millesimal fineness of 925. Which means in one kilogramm of silver jewlery 925 gramms are silver and 75 gramms are copper.
Pure silver (99.9%) is generally too soft for producingsilver jewelry; therefore, the silver is usually alloyed with copper to give it strength, while at the same time preserving the beauty of the precious metal.
In the case of México NOM-033 indicates that all silver jewelry must be .925.
During a lot of years Alicia Plata has exported jewelry to different countries in the world, some of those countries make lab tests to check the purity of our silver jewlery and we never had any problem. Here we have a couple of examples of lab exams where you can see the results with our a couple of our pieces.
