Q: What is this necklace made from?
A: This vintage Tiffany & Co necklace features a sterling silver chain with a prasiolite gemstone pendant and a spring ring clasp. Tiffany notes that sterling silver refers to the .925 silver standard. ([tiffany.com](https://www.tiffany.com/faq/care-repair-faq/how-do-i-care-for-my-sterling-silver/))

Q: How long is the necklace, and where will it sit?
A: The chain measures 40 cm. Necklaces around 40 to 40.5 cm generally sit close to the base of the neck, though the exact fit depends on your neck circumference and how you like your jewellery to sit. ([tiffany.com](https://www.tiffany.com/client-services/size-guide/necklaces-pendants-size.html))

Q: Is prasiolite suitable for everyday wear?
A: Yes, prasiolite is generally suitable for regular wear. As a quartz gemstone it has good everyday durability, but it should still be protected from knocks, abrasive surfaces and harsh chemicals. ([geology.com](https://geology.com/gemstones/prasiolite/))

Q: Will the sterling silver tarnish over time?
A: Yes, sterling silver can tarnish naturally with exposure to humidity, perspiration, cosmetics, chlorine, salt air and strong household chemicals. Keeping it dry and storing it carefully can help reduce tarnish. ([tiffany.com](https://www.tiffany.com/faq/care-repair-faq/does-sterling-silver-tarnish/))

Q: How should I clean and store this necklace?
A: After wear, gently wipe it with a soft cloth. Tiffany advises using silver cleaner sparingly on sterling silver, then rinsing thoroughly in warm water and drying carefully. For gemstone jewellery, avoid abrasive contact, perfumes, cosmetics, household chemicals and ultrasonic cleaning unless a professional advises otherwise. Store it in a safe, dry place when not in use. ([tiffany.com](https://www.tiffany.com/faq/care-repair-faq/how-do-i-care-for-my-sterling-silver/))

Q: Can the chain be lengthened or shortened?
A: Tiffany states that the majority of its necklaces can be altered in length, depending on the style. As this is a vintage second-hand piece, any adjustment should first be assessed by a professional jeweller.
