Q: What are the key details of this Tiffany & Co By the Yard diamond necklace?
A: This necklace features a 0.18 ct diamond in yellow gold, with a stated G colour, VVS1 clarity and 3EX grading. The chain length is 39 cm, giving it a delicate, close-to-the-neck look that suits both everyday wear and layering.

Q: How does a 39 cm necklace typically sit when worn?
A: A 39 cm necklace usually sits high on the neckline, similar to a short necklace or soft choker length depending on the wearer’s neck size and styling preference. If you are unsure about the fit, compare it with a necklace you already own at a similar length before purchasing.

Q: Is a 0.18 ct diamond a noticeable size for daily wear?
A: Yes. A 0.18 ct diamond gives a refined, understated look rather than a bold statement effect. This is one of the reasons By the Yard styles are so popular for everyday wear: they add fine sparkle while remaining elegant, minimal and easy to style.

Q: What do G colour, VVS1 clarity and 3EX mean?
A: G colour is considered near-colourless, so the diamond should appear bright and white to the eye. VVS1 clarity means the diamond has extremely minute inclusions that are very difficult to detect under magnification. 3EX, or triple excellent, refers to excellent cut, polish and symmetry, all of which contribute to strong brilliance and sparkle.

Q: Can this necklace be layered with other jewellery?
A: Yes, this style is especially well suited to layering. Its fine chain and single-diamond design pair beautifully with shorter chokers, slightly longer pendants or mixed-chain looks. Because this piece is 39 cm long, it works particularly well as the top layer in a stack.

Q: Is this necklace suitable for everyday use?
A: Yes, this style is widely loved as an everyday jewellery piece because it is lightweight, versatile and timeless. As with any fine jewellery, we recommend removing it before sports, sleeping, showering or applying perfume and lotions to help preserve the finish and keep the chain in the best possible condition.

Q: What is the condition of this pre-owned piece?
A: The necklace is listed in very good condition with light traces of use. The hardware is described as shiny with light scratches. As this is a vintage and pre-owned item, gentle signs of wear are normal and form part of its character.

Q: What is included with the necklace?
A: According to the product information, this item comes with a box. If you would like confirmation of everything included before ordering, please refer to the product information on this page.

Q: How should I care for a yellow gold diamond necklace like this?
A: Clean it gently with a soft cloth after wear to remove oils and residue. For a deeper clean, use lukewarm water with a small amount of mild soap, then dry thoroughly with a soft cloth. Store it separately to help prevent tangling and surface scratches, and avoid harsh chemicals or abrasive cleaning products.

Q: Is a pre-owned Tiffany & Co diamond necklace still a good investment in style?
A: For many buyers, yes. By the Yard necklaces are known for their timeless, minimalist design and long-term wearability, which is why they remain sought after on the secondary market. Choosing pre-owned also offers access to an iconic fine jewellery style with the charm and value of a carefully curated vintage piece.
