Hallmarks, sometimes also known as fineness marks, indicate the metal at the core of your jewellery piece rather than the outer plating and denote the content of precious metals within.
Some countries require different jewellery stamps, which we meet by adding additional hallmarks to jewellery sold in these countries or which are added by a third party after import and before sale.
In addition to the maker’s mark, the Pandora Crown O appears on some jewellery pieces and the MET hallmark has been introduced for other metals such as 14k rose gold-plated unique metal blend and 14k gold-plated unique metal blend. Older 14k gold-plated pieces made with a sterling silver core are hallmarked with S925. Jewellery made from 14k gold is stamped with 'G' for gold, followed by the purity, stated as pure gold parts per thousand: G585 (58.5% pure gold). Jewellery manufactured prior to 2011 does not carry the “S” or “G” markings, which were added due to regulations in Asia.
Yellow, white, and pink gold
990 = 24k gold = 99.9% gold
750 = 18k gold = 75% gold + alloy
585 = 14k gold = 58.5% gold + alloy
416 = 10k gold = 41.6% + alloy
375 = 9k gold = 37.5% gold + alloy
S925 = sterling silver = 92.5% silver + alloy
Two-tone jewellery designs
Designs made from a two-tone metal combination of sterling silver and 14k gold will normally carry the hallmarks of both alloys. However, on some jewellery pieces the gold details are too small to make it physically possible to add the gold hallmark. In such cases, the S925 G585 ALE hallmark is stamped on the sterling silver part of the design or, as is the case in China, the G585 hallmark is omitted.
