Chanel Coco Mark Rhinestone Necklace

Q: What is the chain length and where will it sit on the neck?
A: The necklace measures approximately 44 cm in perimeter (about 17.3 inches). On most people this sits around the collarbone. Please refer to the Measurements on this page for exact sizing.

Q: Is the length adjustable?
A: This style has a spring ring clasp on a curb chain and is designed to be worn at a fixed length. You may be able to clasp onto an adjacent link for a small adjustment, but there is no dedicated extender.

Q: Are the stones real diamonds?
A: No. The Coco Mark pendant is adorned with rhinestones (glass crystals), a hallmark of Chanel costume jewellery. They offer brilliant sparkle without being precious gemstones.

Q: Is the metal sterling silver?
A: Chanel costume jewellery is typically crafted from base metal (often brass) with a gold- or silver‑toned plating. This piece has a silver‑toned finish rather than solid sterling silver.

Q: How should I care for the rhinestones and plating?
A: Keep the necklace dry and avoid contact with water, perfume, lotions and hairspray. Remove before showering, swimming or exercise. Wipe with a soft, dry cloth after wear and store separately in a dry pouch. Do not soak, steam or ultrasonic clean; moisture can damage foil‑backed rhinestones.

Q: Will the stones loosen or the finish tarnish over time?
A: With vintage costume jewellery, gentle surface wear over time is normal, and exposure to moisture or chemicals can loosen stones and dull plating. Careful handling and dry storage will help preserve shine and longevity.

Q: Where is the Chanel hallmark usually found on necklaces like this?
A: Many vintage Chanel necklaces have a small oval signature plaque near the clasp stamped CHANEL and, on many 1990s‑and‑later pieces, a season code (for example, 03 P). Some styles are stamped on the back of the pendant. Mark formats vary by era.

Q: Can a missing rhinestone be replaced if needed?
A: Yes. A skilled jeweller can generally replace rhinestones with a close match in size and colour, though an exact factory match may not always be available for vintage pieces. For fashion jewellery, a trusted costume‑jewellery specialist is recommended.

Q: What is included with this item?
A: Everything included is listed in the product information section on this page. If an item such as a box or pouch is not listed there, it is not included.
