In 1912, a special mark for platinum was introduced, a dogs head.

Before 1910, French platinum jewelry may have a maker's mark, but it was not hallmarked. Other symbols may be used in combination with these numbers.

Symbols in the form of animals and heads of animals and people, insects, and birds have been used to indicate fineness, place of manufacture, imports and exports. The most easily recognized and commonly seen French mark is the eagles head, in use since 1838, indicating 18 karat gold. The mark can be found on jewelry in any number of places.

Look for it on clasps, side edges, galleries, and pin stems as well as on the back surface of a piece.

Swedish hallmarks after 1912 include a triple crown mark, in a trefoil for local manufacture, and in an oval for imports, along with an S in a hexagon for silver indicating 830 or higher. There will also be a date letter and number, a city mark and a makers mark.

The most accurate definition of a hallmark is the mark or marks stamped, impressed, or struck on gold, silver, or platinum which indicate fineness or karat (also called quality or purity marks).
