In Sterling Silver there are 925 parts of silver in a thousand or 92.5% silver. .935 silver then has more silver content than Sterling Silver with 935 parts silver per thousand making it 93.5% silver. Also, .935 silver is more tarnish resistant than Sterling Silver and it oxidizes much more slowly, meaning you don’t have to polish your jewelry nearly as often.
