Georg Jensen Acorn Silver Brooch

Q: What is this brooch made from and how is it marked?
A: It is crafted in solid sterling silver (925). Vintage Georg Jensen silver typically carries hallmarks such as Georg Jensen within a dotted oval, “925 S” and “Denmark”, and sometimes “Sterling” plus a design number. Please refer to our photos for the exact marks on this piece.

Q: What is the Acorn motif and when was it introduced?
A: The Acorn motif is part of Georg Jensen’s classic design language, created in the 1910s by designer Johan Rohde. First seen in silverware, the motif’s organic acorn-and-leaf details have been interpreted across jewellery ever since, giving a timeless, elegant look.

Q: How can I estimate the age of a vintage Georg Jensen brooch?
A: Dating is best done by studying the hallmarks. Post‑1945 pieces typically show the dotted‑oval Georg Jensen maker’s mark alongside “925 S” and “Denmark”, while earlier eras used slightly different stamps. Designer initials and any model numbers can also help narrow the production period. If you’d like help reading the marks in our photos, contact us and we’ll assist.

Q: What are the measurements of this brooch?
A: Approximately 5.7 cm high, 1.7 cm wide and 0.5 cm deep. Please see the Measurements on this page for confirmation before purchasing.

Q: How secure is the pin closure and where should I place it?
A: The traditional pin fastening is secure when anchored through denser fabrics such as jacket lapels, coats, knitwear or seams. For extra stability, you can add a discreet brooch guard or a small piece of felt behind the fabric to distribute weight.

Q: Can I wear it as a pendant?
A: Yes. A simple brooch‑to‑pendant converter slides over the pin so you can hang the brooch on a chain. It’s a reversible, non‑invasive option and widely available from jewellery supply stores.

Q: How should I clean and care for the sterling silver?
A: After wearing, wipe gently with a soft silver‑polishing cloth. For a deeper clean, briefly wash by hand in lukewarm water with mild soap, rinse and dry thoroughly. Avoid harsh chemicals, toothpaste, ultrasonic cleaners, or abrasive pads. Store the brooch dry, ideally in a soft pouch with an anti‑tarnish strip to reduce natural tarnish forming over time.

Q: Is sterling silver suitable for sensitive skin?
A: Sterling silver is 92.5% pure silver alloyed primarily with copper and is generally well tolerated. If you have known metal sensitivities, we recommend wearing the brooch over clothing and discontinuing use if any irritation occurs.

Q: What is included with my purchase?
A: Everything included is listed under the product information section on this page. If a branded box, dust pouch or other extras are not listed there, they are not included—please ask us if you’d like us to confirm.

Q: How does A Retro Tale authenticate this item?
