ChanelCoco Mark Heart Rhinestone Necklace

Q: Is this Chanel Coco Mark Heart Rhinestone Necklace authentic?
A: Yes. Every item at A Retro Tale is rigorously vetted by our in‑house experts and sold with our authenticity commitment. Shop with confidence.

Q: What is it made from? Is the metal solid silver?
A: Chanel costume jewellery is typically crafted from plated base metal in a silver‑tone finish with glass rhinestones. Unless a piece is specifically hallmarked as sterling silver, you should assume it is silver‑tone plating rather than solid silver. If you’d like us to confirm any composition details on this necklace, just ask.

Q: What are the measurements and how will it sit when worn?
A: The chain measures approximately 40 cm in perimeter (about 16 in), which generally sits at the base of the neck/collarbone on most wearers. The pendant/charm area is listed at around 2.2 cm (height) x 1.0 cm (width) x 0.5 cm (depth). If you’d like the precise drop length or gram weight, we can measure it for you.

Q: How does it fasten? Is the length adjustable?
A: It features a lobster clasp closure. Some Chanel necklaces include a short extender; if none is present here, a jeweller can add a discreet extender to fine‑tune the fit without altering the original chain.

Q: What hallmarks or stamps should I expect on a Chanel necklace?
A: Most vintage Chanel necklaces carry a small oval or round plaque stamped CHANEL and often “Made in France” or “Made in Italy,” sometimes accompanied by a season/date code. Placement varies by era (near the clasp, as a hang tag, or on the reverse of a charm). Please refer to our close‑up photos to view any stamps on this piece.

Q: Is it suitable for sensitive skin? Is it nickel‑free?
A: Fashion/costume jewellery may contain nickel or other alloys. If you have sensitivities, consider applying a clear barrier product to contact points, wearing the necklace over clothing, and keeping skin dry. Discontinue wear if irritation occurs and consult a clinician if needed.

Q: How should I care for the silver‑tone plating and rhinestones?
A: Keep the necklace dry and avoid perfume, lotions, hairspray and hand sanitiser. After wear, gently wipe with a soft, dry microfibre cloth. Do not soak, use ultrasonic cleaners or chemical dips—moisture and harsh chemicals can dull plating and may affect rhinestone settings/foils. Store it separately in a pouch or box away from humidity and direct sunlight.

Q: Can I wear it in the shower, swimming, or during exercise?
A: We recommend removing Chanel costume jewellery before showering, swimming or vigorous exercise. Water, sweat and chlorine can accelerate wear to plated finishes and may loosen or cloud rhinestones over time.

Q: Can it be repaired, resized or replated?
A: A competent jeweller can often add a short extender, adjust/replace the clasp, secure or replace missing rhinestones, and perform light replating if needed. Any modification may affect originality and resale value; feel free to ask us for recommendations to trusted specialists.

Q: What condition should I expect, what is included, and can I return it?
A: This necklace is in Very Good Condition with minor signs of careful wear possible, consistent with its vintage nature. It comes with a box as listed. Returns are accepted under our standard policy—please see our Returns page for eligibility, timeframes and conditions, and ensure the item is returned in the same condition received.
