The 835 mark indicates the purity of silver jewelry, by parts per thousand. So "925" denotes sterling silver, at .935/1000, while "835" is alloyed to a greater extent with other metals. 835 silver was used (most commonly in vintage European jewelry) when "hallmark" or sterling quality was not specifically desired.
835 is an old German mark that is no longer in use today for gold. Take it to a goldsmith and have it tested.
