Designer Jewellery Signatures & Markings: An Evidence Checklist
A mark is one piece of evidence. It should be read alongside the object’s construction, materials, condition and documented history.
Record before interpreting
Take a full photograph of the reverse, followed by close views of every stamp, plaque, tag and inscription. Record the wording exactly, including punctuation and any country, number or copyright symbol. Note whether a mark is part of the body, on a separate plaque or on a removable component.
Ask what the mark actually establishes
- A designer name is an attribution to investigate.
- A numeral may have several possible meanings; do not assume it is a year.
- A precious-metal claim needs appropriate evidence beyond a gold or silver colour.
- A mark on a replaceable clasp may not establish the history of the entire necklace.
Compare like with like
Museum records can help by separating designer, maker, date and materials. The Met’s Chanel and Gripoix necklace record, for example, names the design house and maker separately. Apply that discipline to your own notes: who is being credited, for what, and on which evidence?
Do not rely on a single online chart or a cropped signature photograph. Consider dimensions, fastening mechanics, stone settings and the relationship between front and back. If findings conflict, record the uncertainty rather than choosing the most flattering interpretation.
Keep an object file
Save photographs, measurements, invoices and source links together. Label seller statements as seller statements. Keep your own observations separate from externally documented facts.
