Q: Is this Gucci GG Running Diamond 18kt 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 materials is it made from? Is it solid gold?
A: The GG Running Diamond necklace is fine jewellery crafted in solid 18‑carat gold (Au 750) with diamond detailing. Gold colour and exact specifications can vary by release (e.g., yellow, white or rose gold). It is not plated unless otherwise stated. If you’d like us to confirm the precise gold colour and stone details for this piece, please contact us.

Q: What are the diamond specifications (carat weight, colour and clarity)?
A: Diamond size and total carat weight vary between versions of the GG Running necklace, and details are not always stamped on the piece. Gucci typically uses brilliant‑cut diamonds in pavé or micro‑pavé settings for this design. Please review the photos and get in touch if you’d like us to share any documented specs we have for this necklace.

Q: What is the chain length and is it adjustable?
A: Many GG Running necklaces feature an adjustable chain with one or more jump rings (commonly around 38–42–45 cm ranges), but lengths vary by model and year. Please refer to the “Perimeter Necklace” measurement on this page; if not listed, message us and we’ll measure the exact wearable range for you.

Q: How does it fasten?
A: Gucci fine necklaces typically use a lobster clasp for secure closure. Please check the close‑up photos on this listing to see the exact fastening on this piece, or contact us for confirmation.

Q: What hallmarks or stamps should I expect?
A: Authentic Gucci fine jewellery usually bears GUCCI, “Made in Italy”, an Au 750 (18k) fineness mark, and sometimes a serial or maker’s mark. Placement can vary; our high‑resolution photos will show any visible hallmarks on this necklace.

Q: Is it suitable for daily wear and can it get wet?
A: 18k gold and diamonds are durable, but we recommend removing the necklace before swimming, showering, exercising or sleeping to protect the delicate chain and settings. Avoid chlorine, saltwater and cosmetic products which can dull the finish over time.

Q: How should I clean and care for it?
A: After wear, gently wipe with a soft, dry microfibre cloth and store separately in a pouch to prevent scratches. For a deeper clean, use lukewarm water with a tiny amount of mild soap and a very soft brush, then pat dry thoroughly. Avoid harsh chemicals and ultrasonic cleaners on pavé settings; periodic professional checks help ensure stones remain secure.

Q: Can the chain be resized or repaired?
A: A professional jeweller can usually shorten or extend the chain (via additional links or extender) and service the clasp if needed. Any alterations may affect originality and resale value. Gucci boutiques may offer service at their discretion; we’re happy to advise on reputable specialists.

Q: Is it hypoallergenic? Does it contain nickel?
A: 18k yellow and rose gold alloys are generally well‑tolerated; some white gold alloys can contain trace nickel. If you have sensitivities, consider confirming the gold colour, and discontinue wear if irritation occurs.

Q: What condition should I expect and what is included?
A: As a pre‑loved piece, light wear such as micro‑scratches may be present unless stated otherwise. Please review the condition notes and photos carefully. Only accessories specifically shown or listed (e.g., Gucci box/pouch) are included.

Q: Can I return it if it doesn’t suit?
A: Yes—returns are accepted in line with our policy. Please see our Returns page for eligibility and timeframes. Items must be returned in the same condition as received.
