Q: What is this Chanel Coco Mark Rhinestone Brooch made from?
A: It is a vintage Chanel costume jewellery piece crafted in silver‑tone metal and set with clear rhinestones (often called strass). Strass refers to brilliant glass crystals commonly used in Chanel brooches. It is not solid sterling silver.

Q: How big is it and where does it look best?
A: The brooch measures approximately 3 × 4 × 1 cm. It’s a versatile size that sits beautifully on a blazer lapel, coat, structured knit, or at the shoulder of a dress. It can also be used to secure a scarf or add sparkle to a hat or denim jacket—place it where the fabric is firm enough to support it.

Q: Will the pin damage delicate fabrics like fine silk?
A: To protect delicate weaves, avoid piercing very fine silk or lightweight knits. Instead, pin through a seam, facing, or a thicker area, or use a magnetic brooch back to avoid holes. On very open knits, go through several strands or a reinforced spot so the weight is supported.

Q: How secure is the clasp, and how do I keep it from coming loose?
A: This piece uses a classic pin closure with a locking catch. For extra security—especially on heavier fabrics or when wearing on a bag—add a small rubber earring back or a locking pin clutch on the pin before closing the catch, or reinforce from the inside with a small piece of felt.

Q: How should I clean and care for the rhinestones and finish?
A: Keep it dry and avoid contact with perfume, lotions, hairspray, and household chemicals. Gently wipe with a soft, dry, lint‑free cloth after wear. Do not soak or immerse rhinestone pieces—many stones are foil‑backed and moisture can cause clouding. Store it separately in its box to prevent scratches and minimise humidity exposure.

Q: Can missing rhinestones be replaced?
A: Yes, rhinestones on costume jewellery can often be replaced. Chanel boutiques may assess repair options case by case, and specialist costume‑jewellery restorers can source and set matching strass. Turnaround time and cost vary with stone size and availability; contact us if you’d like recommendations.

Q: Is the finish prone to tarnishing, and how can I prevent it?
A: Like most plated costume jewellery, the silver‑tone finish can dull with exposure to moisture, cosmetics, and skin oils. Wipe it clean after each wear, avoid prolonged humidity, and store it in a dry box or pouch away from direct sunlight to help preserve the shine.

Q: How do you authenticate a vintage Chanel brooch like this?
A: Our in‑house experts examine materials, construction, pin and catch style, and the signature plaque or stamp on the reverse (fonts and formats vary by era). We cross‑check hallmarks and design details against known references and stand behind the authenticity of every item we sell.

Q: What comes with this brooch?
