Identifying items with Sterling Silver Hallmarks :

To purchase sterling silver in the form of jewelry, silverware, candelabras, antiques or accents one must understand the concept of sterling silver. Sterling silver is an alloy of silver containing 92.5% pure silver and 7.5% other metals, usually copper.

Any “silver” without a suitable Sterling silver hallmark guarantee should be treated as “white metal” as there is no guarantee as to how much silver the metal contains.

How To Identify Sterling Silver Hallmarks

Identifying and authenticating antique and period jewelry proposed to be Sterling Silver is based on experience and knowledge. The minimum fineness is 925 or 92.5 % purity.

The most common marking for Sterling Silver are as follows:

  • 925
  • Ster
  • Sterling
  • Sterling Silver
  • Stg

The difficulty with hallmarking systems other than those of the United Kingdom and North America are that in most cases one cannot pinpoint the manufacture to a specific year, but instead to a range of years during which the company was in business

* Quick Tip: *

One way to give yourself alittle reassurance in testing an item for silver content is to use a magnet, simply touch the magnet to the item in question.

A strong magnet enables you to make a first test for real silver, gold or platinum quickly and efficiently. Neither gold, silver, nor platinum are magnetic, and if an item is strongly attracted to a magnet, you can set it aside as it has no value as a precious metal.

Why Sterling Silver?

Sterling silver is used is because fine silver (99.9% pure) is too soft for producing large functional objects, and in Sterling the silver is usually alloyed with copper to give strength whilst preserving the ductility of the silver and high precious metal content.
