What does sterling silver mean?
“Sterling silver” is the term used for 925 silver, an alloy containing 92.5 % pure silver (Ag) and 7.5 % other metals, typically copper. It is one of the most widely used grades.

All SPARK jewelry is made of sterling silver. Whether rhodium-plated or gold-plated, every piece bears the 925 mark.

The term “sterling” has its roots in British currency history. In medieval England, silver pennies were minted from an alloy containing 92.5 % pure silver. This metal was stable and valued, leading to its widespread use in trade. The word “sterling” comes from Old English “steorling,” meaning “of high quality” or “of high weight.” That is why 925 silver is called “sterling silver,” to emphasize its high quality.

Sterling silver is widely used in jewelry, cutlery, tableware, and decorative objects. Its popularity comes from the balance between durability and beauty, as well as its workability, allowing for detailed designs.

How is silver marked in Poland?
In Poland, silver is marked with an official hallmark on the object. This is controlled by the Assay Office, which certifies the quality and grade of precious metals.

The official hallmark shows a woman’s head, the grade indicated in numbers, and a letter for the city of the Assay Office (e.g., G – Gdańsk, W – Wrocław). This hallmark confirms that the item contains the correct silver content according to standards.

Additional marks include:

925 (stamped as “925” or “Ag 925”), meaning 92.5 % pure silver.

800 (stamped as “800” or “Ag 800”), meaning 80 % pure silver.

These appear next to the official hallmark to indicate grade and purity.

How to read silver marks?
Reading silver marks requires some knowledge of symbols used by makers and assay offices.

The silver grade is usually indicated with numbers such as “925” for 92.5 % silver or “800” for 80 %. In some countries, a special hallmark symbol is also used.

Maker’s marks appear on many items: initials, brand name, graphic symbol, or catalog number, identifying the producer.

Marks of origin can also appear, showing the city or country of production.

On collectible items, there may be a hallmark indicating the year of manufacture.

Other artistic or decorative marks may also be present, without relating to grade or maker, but serving an aesthetic or symbolic purpose.

Interpretation of marks depends on the region, period, and type of item. If in doubt about a specific mark, it is advisable to consult a silver expert or an assay office.
