Researching the history of inherited jewellery

Begin with the hallmarks

Inherited jewellery often carries small marks that are easy to overlook. These are hallmarks, and they are your first and most reliable clue. Use a jeweller's loupe or a strong magnifying glass. Look inside ring bands, on the back of brooches, on clasps, bails, and the stems of spoons or forks if the piece is silver. British hallmarks usually combine four elements: the maker's mark, the assay office mark, the standard mark, and the date letter. The standard mark tells you the metal purity, such as 925 for sterling silver or 375 for 9ct gold. The date letter is a single letter in a shield or square, and it changes every year. Without the assay office mark, the date letter can be ambiguous. Here are the most common places to check:

• Inside ring shanks
• On the reverse of brooches and lockets
• On clasp tongues and bails
• On the edges of bangles and cufflinks

Decoding the date letter and assay office

The assay office mark is a symbol. For example, the Birmingham assay office uses an anchor, London uses a leopard's head, Sheffield a rose, Edinburgh a thistle, and Dublin a harp. Once you know the office, you need a date letter chart for that office. Date letters run in cycles, often changing in May or July, and the style of the letter — its font and shield shape — matters. You can find these charts in reference books at local libraries or ask an experienced antiques dealer. Remember that not all jewellery is hallmarked: pieces made before 1973 may have exempt items, and foreign jewellery often has different marks. If you find no hallmark, don't despair; style and inscription can still help.

Style as a dating tool

Design and materials can narrow down a period even without a hallmark. Victorian jewellery (1837–1901) often features gold, jet, cameos, and mourning motifs like hair or black enamel. Edwardian pieces (1901–1910) are delicate, with platinum, filigree, and fine diamonds. Art Deco (1920s–1930s) is geometric, with bold colours, enamel, and contrasting metals. Mid-century pieces (1950s–1960s) tend to be sculptural and use gold and semi-precious stones. But be cautious: styles were revived. A 1970s brooch might look Victorian. Use style as a supporting clue, not a final answer.

Inscriptions and engravings: personal meanings

Engravings turn a piece of jewellery into a personal document. Look for initials, full names, dates, and short messages. They might be inside a ring band, on the back of a locket, or along the pin of a brooch. Common examples include:

• "M.B. to E.H. 1897" — likely a wedding or anniversary gift.
• "In memory of..." — a mourning piece.
• "15.8.21" — a birthday or christening date.

These inscriptions can reveal family names, important dates, and relationships. But be aware that engravings might have been added later, perhaps for a special anniversary. Compare the wear on the engraving with the rest of the piece. If it looks fresh, it may be recent.

Researching the maker's mark

The maker's mark, also called the sponsor's mark, is usually a set of initials in a rectangle or shield. It identifies the workshop or individual who sent the piece for assay. Thousands of makers operated across the UK, and many are documented in trade directories and assay office records. You can search local archives, census returns, and old newspapers. Start with the town where your family lived, as jewellery was often bought locally. A maker's mark of "W.H." might belong to a small workshop in Birmingham or Sheffield. While you may not find a famous name, identifying the maker adds a layer of understanding to your family's story.

Recording and preserving your findings

As you research, keep a dedicated notebook or digital file for each piece. Photograph the hallmarks with a macro lens or a phone camera with a close-up setting. Write down every detail: measurements, metal colour, stone types, and any family stories you remember. Store jewellery in acid-free tissue or a soft pouch, away from direct sunlight and damp. Avoid harsh cleaning chemicals, which can remove patina and even damage hallmarks. If you are unsure, consult a conservator. By recording your research, you create a valuable resource for future generations, turning a box of inherited jewellery into a well-documented family archive.
