The authenticity of this piece of jewelry has been checked and certified by Kathrine, who has 20 years of experience in vintage and luxury jewelry.

Q: Is this Van Cleef & Arpels Vintage Alhambra Chalcedony 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 chalcedony a real gemstone?
A: This piece is fine jewellery crafted in solid 18k white gold with a single Vintage Alhambra motif set in genuine chalcedony (a natural variety of quartz). The chalcedony’s colour and translucency can vary subtly from stone to stone, which is normal for natural materials.

Q: What are the measurements and how will it sit when worn?
A: The necklace perimeter is approximately 42 cm. The Alhambra motif is about 1.5 cm (height) x 1.5 cm (width) x 0.4 cm (depth). At 42 cm it typically sits at, or just below, the collarbone on most wearers. If you’d like the precise drop length or gram weight, message us and we’ll measure it for you.

Q: How does it fasten and is it secure?
A: It features a lobster clasp closure in 18k white gold. Always ensure the clasp is fully engaged before wear and avoid hard impact to keep the mechanism in good order.

Q: What hallmarks or stamps should I expect on a VCA Alhambra necklace?
A: Authentic Van Cleef & Arpels pieces typically bear the brand signature (“Van Cleef & Arpels” or “VCA”), an 18k fineness mark such as “Au750/750,” and a unique serial number—often on a small plate or ring near the clasp. French assay marks may also be present depending on era. We’re happy to reconfirm the stamps on this specific necklace.

Q: Is the white gold rhodium‑plated? Will it need maintenance over time?
A: Many 18k white‑gold pieces are finished with a thin rhodium layer for a bright white appearance. Over years of wear, this can soften and may be refreshed by a jeweller through re‑rhodium plating. This is routine maintenance for white‑gold jewellery.

Q: Is it suitable for sensitive skin? Is white gold nickel‑free?
A: White gold is an alloy; some 18k white‑gold formulations include small amounts of nickel while others use palladium. If you’re sensitive to nickel, consider limiting prolonged moisture contact, and discuss palladium‑alloy or protective rhodium finishes with a jeweller. Discontinue wear if irritation occurs and contact us for guidance.

Q: Can the chain length be adjusted or extended?
A: The piece is listed at 42 cm. A competent jeweller can add a short extender for temporary length or discuss a permanent adjustment; note that non‑original alterations may affect authenticity assessment and resale value. Ask us for guidance before making changes.

Q: How should I care for chalcedony and white gold?
A: Keep it dry and away from perfume, lotions, hairspray and cleaning chemicals. After wear, gently wipe with a soft, dry microfibre cloth. For chalcedony, use mild warm soapy water and a soft brush sparingly; avoid ultrasonic cleaners and harsh dips. Store separately to prevent scratches.

Q: Is chalcedony suitable for everyday wear?
A: Chalcedony is a tough microcrystalline quartz (typically rated around 6.5–7 on the Mohs scale), making it well‑suited to regular wear. As with all gemstones, avoid knocks and abrasive contact to preserve its polish.

Q: What condition should I expect, what is included, and can I return it?
A: This necklace is in Very Good Condition with light signs of careful wear possible unless stated otherwise. This listing includes no accessories unless specifically shown or stated. 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.

Q: Where is it from and can you confirm country of origin?
A: The piece is labelled France. Origin marks and workshop stamps can vary by era; please refer to our photos for any country‑of‑origin stamps present, and contact us if you’d like us to reconfirm before purchase.
