Q: What is the diamond size/carat weight? A: Diamonds by the Yard necklaces are produced in several diamond sizes. The exact carat weight can vary by model and era. If you’d like us to verify the approximate carat weight or the stone’s diameter (mm) for this specific necklace, message us and we’ll measure it and report back.
Q: What is the chain length and is it adjustable? A: Our listing notes a perimeter of approximately 44 cm. Some Tiffany chains include an additional jump ring for a shorter setting, but this varies by piece. Please review the close‑up photos to see the available rings, and contact us if you’d like the precise wearable range (shortest–longest) or the pendant drop—we’re happy to measure it for you.
Q: How should I care for 18K gold and the diamond? A: Keep it away from perfume, lotions, hairspray and chlorine. After wear, gently wipe with a soft, dry microfibre cloth. For occasional cleaning, use lukewarm water with a drop of mild soap, a very soft brush, rinse well and dry thoroughly. Avoid ultrasonic cleaners and chemical dips. Store separately in a pouch or box to prevent scratches.
Q: Can the length be altered or can Tiffany service this piece? A: A competent jeweller can often add a small extender or extra jump ring to fine‑tune the length, and clasps can be replaced if needed. Tiffany boutiques may offer cleaning/polishing and some repairs at their discretion. Any modification can affect originality and resale value—we don’t modify items in‑house but can recommend reputable specialists on request.
Please note that the majority of our items are vintage and therefore have tales to tell unless stated otherwise. Therefore, please look at pictures, descriptions and measurements provided as they give you the best idea of the story this item has to tell.
* Please note that when you buy a vintage product, the dimensions may vary slightly from a new one depending on previous care and storage.

Delivery & Returns
Q: Is this Tiffany & Co Diamonds by the Yard 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 and is the diamond real? A: This necklace is crafted in solid 18K yellow gold (not plated) and features a single round brilliant diamond in a bezel setting. Tiffany fine jewellery uses real diamonds. Please review the features and photos, and contact us if you’d like us to confirm any aspect of the composition for this exact piece.
Q: What is the diamond size/carat weight? A: Diamonds by the Yard necklaces are produced in several diamond sizes. The exact carat weight can vary by model and era. If you’d like us to verify the approximate carat weight or the stone’s diameter (mm) for this specific necklace, message us and we’ll measure it and report back.

Please review the close‑up photos to see the available rings, and contact us if you’d like the precise wearable range (shortest–longest) or the pendant drop—we’re happy to measure it for you.
Q: How does it fasten and is it secure for everyday wear? A: It secures with a spring ring clasp. The diamond is bezel‑set, which offers good protection for daily wear; however, as with all fine jewellery, avoid hard knocks, remove it for sport or heavy activity, and store it safely when not in use.
Q: What hallmarks or stamps should I expect? A: Tiffany necklaces typically bear the “Tiffany & Co.” or “T&Co.” signature and “750” (for 18K gold). Depending on era and production, you may also see a country of origin (e.g., Italy/Spain/USA) and additional maker marks. Stamps are often on the clasp tag and/or near the bezel. Our photos show any marks present on this piece; note that not every vintage example carries a visible serial number.
Q: Is it suitable for sensitive skin? Is there any nickel? A: 18K yellow gold is generally alloyed without nickel and is usually well‑tolerated. Those with metal sensitivities should still monitor comfort; discontinue wear if irritation occurs and contact us for guidance.
Q: How should I care for 18K gold and the diamond? A: Keep it away from perfume, lotions, hairspray and chlorine. After wear, gently wipe with a soft, dry microfibre cloth.

Any modification can affect originality and resale value—we don’t modify items in‑house but can recommend reputable specialists on request.
Q: What condition should I expect, what is included, and can I return it? A: It is in Very Good Condition with gentle wear possible unless noted otherwise. This listing includes a box; only accessories specifically shown or listed are included. 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.
