When buying silver jewelry, make sure there are no visible blemishes or imperfections
on the piece. Check to make certain that fasteners, clasps and catches work properly
and are secure. Check pin backs and earring posts for strength and durability. Lay
silver chains flat to make certain their links don't kink or bend.
When making a silver purchase, always look for the mark 925, .925
or Sterling Silver, the mark is proof that the silver piece you are buying is 92.5%
pure, rather than containing a lower percentage of silver, being an imitation made
with other alloys or being plated with only a thin layer of silver. Having a lower
silver content might cause your silver jewelry to darken even with the slightest
exposure to humidity. If the content of silver is higher than 92.5%, the piece might
be too soft and won't stand up to everyday wear.
