What is a Hallmark?
A hallmark is an official mark or series of marks stamped onto precious metals to certify their purity and authenticity. British hallmarking dates back to the 14th century and remains one of the oldest forms of consumer protection.
Historical Context of Hallmarking in Antique Gold
Hallmarking dates back over 700 years, originating in Europe to protect consumers by confirming gold's purity. In the UK, the system was established by the Goldsmiths' Company in the 14th century, where a series of marks were created to identify the maker, the purity of the metal, and the Assay Office that verified the quality.
Antique hallmarks are typically found on gold jewellery dating back to the Georgian (1714–1837), Victorian (1837–1901), Edwardian (1901–1910), and Art Deco (1920s–1930s) periods. Each era reflects distinct design trends, techniques, and hallmarking standards. Recognising these hallmarks can help date and identify an item accurately.
Delve deeper into these eras by exploring our collection of antique jewellery, where each piece tells a unique story.
Key Types of Hallmarks in Antique Gold
Compulsory Marks
By law, British gold hallmarks must include specific marks to verify their authenticity. These include:
Millesimal Fineness Mark: A number representing gold purity (e.g., 375 for 9K, 750 for 18K).
Assay Office Mark: Identifies where the gold was tested.
Sponsor’s (Maker’s) Mark: The initials or symbol of the manufacturer or jeweller.
Purity Marks
One of the primary functions of a hallmark is to indicate the purity of the gold. In antique gold, you may encounter marks such as:
Carat System: Indicating the proportion of gold in a piece (e.g., 9K, 15K, 18K, 22K, 24K).
Millesimal System: Commonly used in Europe, with numbers like 375 (for 9-carat), 750 (for 18-carat), or 999 (for pure gold).
Standard Mark: This is a key part of the purity mark system. The standard mark indicates the precise purity of the gold, often represented as a number (such as 375, 750, or 999). It provides consumers with assurance that the gold is of the stated quality.
These marks often appear alongside assay office stamps or makers' marks.
Assay Office Marks
The Assay Office mark tells you where the piece was tested for purity. In Britain, major assay offices include:
London – Leopard’s head
Birmingham – Anchor
Sheffield – The Yorkshire rose
Edinburgh – The Scottish Thistle
These marks are often accompanied by the date letter, which indicates the year the piece was assayed.
Date Letter Mark
Date stamps indicate the year an item was assayed, changing annually since 1570.
Example:
A = 1900
B = 1901
C = 1902, and so on.
Traditional Fineness Mark
Before the introduction of the millesimal system, antique gold was marked using symbols such as the crown, which represented gold purity in older pieces.
Convention Hallmarks
Since the 1970s, the International Convention on Hallmarks has allowed recognised marks to be accepted across member countries, ensuring easier trade and verification of authenticity. Some antique pieces may carry both British and foreign hallmarks.
How Antique Hallmarks Differ from Modern Hallmarks
Antique hallmarks often feature old-style fonts, elaborate symbols, or discontinued carat standards (e.g., 15K, which was abolished in 1932).
Modern hallmarks follow the same principles but adhere to updated legal requirements and standardised marks.
Some antique gold may lack a hallmark due to wear or older regulations.
How to Identify an Antique Gold Hallmark
1. Locate the hallmark – Usually found inside rings, on clasps, or on the back of pendants.
2. Check for purity marks – Look for carat or millesimal numbers.
3. Identify the assay office – Compare symbols to official marks.
4. Look for a maker's mark – Initials or a unique stamp can provide provenance.
5. Use a date letter reference – Match the letter to the correct year.
While many antique gold hallmarks are easy to spot, identifying and verifying authenticity can be complex. If you're unsure about a piece, professional appraisal services can provide expert insight and confirmation.
