Tiffany & Co Single Diamonds by the Yard Necklace

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 material is it made from? Is it solid gold?
A: This necklace is crafted from solid 18k yellow gold (indicated by the 750 hallmark) and features a single genuine round brilliant diamond. It is not gold‑plated. Please review the close‑up photos to see the warm gold tone and bezel setting.

Q: What are the measurements and how will it fit?
A: The necklace has a perimeter of approximately 40 cm (16 inches). This is a classic collar length that typically sits at the hollow of the throat or on the collarbone. It is ideal for wearing alone as a delicate accent or layering with longer chains.

Q: Who designed this collection?
A: This piece is part of the iconic “Diamonds by the Yard” collection designed by Elsa Peretti for Tiffany & Co. It revolutionized diamond wearing with its concept of diamonds for everyday elegance.

Q: Can I wear it every day? Can I shower with it?
A: Elsa Peretti intended these pieces to be worn daily. The bezel setting securely protects the diamond. However, to maintain its maximum sparkle and prevent soap buildup, we recommend removing it before showering, swimming, or applying lotions and perfumes.

Q: How does the clasp work?
A: It features a classic spring‑ring clasp, which is the standard closure for this delicate chain style. It is secure and discreet, blending seamlessly with the fine links.

Q: What hallmarks or stamps should I look for?
A: You should expect to see small plates near the clasp stamped with “TIFFANY & CO.”, “©PERETTI”, and “750” (the standard mark for 18k gold). Exact placement can vary slightly by production year; our photos show the hallmarks present on this specific piece.

Q: How should I care for the diamond and gold?
A: To clean, use warm water with a drop of mild dish soap and a soft toothbrush to gently scrub the diamond and chain. Rinse thoroughly and pat dry with a soft, lint‑free cloth. Store it in its pouch to prevent the chain from tangling.

Q: What condition is it in and what is included?
A: This necklace is in Very Good Condition (Ref: 353326) and may show minimal signs of careful wear. Unlike many vintage listings, this piece includes its original dust bag and box. Returns are accepted under our standard policy—please ensure the item is returned in the same condition received.
