Q: What does “Coco Mark” mean on this necklace?
A: “Coco Mark” refers to Chanel’s interlocking CC logo. It is a signature motif used across Chanel jewellery and identifies the brand’s design heritage.

Q: Is this necklace solid gold?
A: No. Chanel costume jewellery is typically crafted from non-precious base metals with a gold-tone plated finish rather than solid gold. This piece is described as gold-tone hardware, consistent with Chanel’s fashion jewellery practice.

Q: What is the length and how will it sit when worn?
A: The chain measures approximately 56 cm (about 22 inches), a matinee length that generally sits around the upper chest. The pendant is about 2.5 × 2.5 × 1 cm; please see Measurements for precise sizing.

Q: Can the length be adjusted?
A: The spring ring clasp may allow slight shortening if it can fasten into different chain links. If your preferred fit requires more adjustment, a small chain extender can be added by a jeweller.

Q: How should I care for vintage Chanel costume jewellery?
A: Keep it dry, avoid contact with perfume, lotions, and hairspray, and remove before exercising or bathing. After wear, gently wipe with a soft, dry cloth and store separately in a soft pouch to minimise scratches and tangling.

Q: Will the gold-tone finish tarnish or fade over time?
A: Plated finishes can show wear with friction, moisture, or chemicals. Careful handling and dry, dark storage help preserve the colour and shine. Light signs of use are normal for vintage pieces and are noted in the condition report.

Q: How is authenticity verified for this necklace?
A: Authentic Chanel pieces often feature a maker’s stamp or oval plaque and consistent construction details. Stamps alone can be copied, so our in-house experts authenticate using multiple checkpoints including materials, workmanship, and hallmark style for the era.

Q: Where was this item made?
