Q: What length is this necklace, and where will it sit? A: This necklace has a 40 cm chain, which is close to 16 inches. On most people, that length sits at or just below the collarbone for a neat, close-to-the-neck look. Exact placement will vary depending on your neck size and how you like your necklaces to fit.
Q: What size is the heart key pendant? A: The key heart pendant measures approximately 2.5 cm in height and 1 cm in width. Its delicate scale makes it easy to wear on its own or layered with longer chains.
Q: Is this a good everyday necklace or better for occasions? A: It works beautifully for both. The delicate 40 cm length and single diamond make it refined enough for daily wear, while the Tiffany Keys design gives it a distinctive look that also suits gifting and special occasions.
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.

Q: What are the main features of this necklace? A: This vintage Tiffany & Co. design features silver-tone metal, a delicate link chain, a heart key pendant set with a single diamond, and a spring ring clasp closure.
Q: What does the Tiffany Keys motif represent? A: Tiffany Keys designs are often associated with independence, optimism and new possibilities. The heart-shaped key gives this piece a romantic, feminine feel while keeping the signature symbolic look of the collection.
Q: Is some wear normal on a vintage Tiffany necklace like this? A: Yes. Fine silver jewellery can develop light surface marks and gentle patina with age and wear. This piece is listed in Very Good Condition, and the hardware is described as shiny with light scratches, which is consistent with careful previous use.
Q: Will the silver-tone finish tarnish over time? A: Silver jewellery can naturally tarnish over time, especially if exposed to moisture, chemicals or long periods of storage. Occasional gentle cleaning and dry storage will help preserve the shine.
Q: How should I care for this necklace and its diamond detail? A: Wipe it gently with a soft cloth after wear and store it dry in its box or dust bag when not in use. Avoid chlorine, bleach, perfume, lotions and abrasive cleaners. If it needs a deeper refresh, use a non-abrasive jewellery cleaner suitable for silver and delicate stone-set pieces, or have it professionally cleaned.
Q: Does this necklace come with original packaging? A: Yes. According to the product information, this item comes with a box and dust bag.
Q: Is this necklace authenticated? A: Yes. Every item sold by A Retro Tale is carefully inspected for authenticity by in-house experts before it is listed for sale.
