FAQs

Pawning your diamond necklace in Central London offers a temporary financial solution without permanently parting with your cherished piece. At New Bond Street Pawnbrokers, we provide short-term loans, allowing you to reclaim your necklace upon repayment. This option is particularly beneficial if you anticipate future value appreciation or have a strong attachment to the jewellery.

Our Mayfair-based service offers loans against premium diamond necklaces from esteemed brands such as Cartier, Van Cleef & Arpels, Graff, Harry Winston, Tiffany, and Bulgari. Our expertise ensures accurate auction-based diamond necklace valuations for a wide variety of brands.

We specialise in diamond necklaces. While we don’t typically offer loans on plain gold chains, we do consider gold necklaces featuring significant diamond elements or those from luxury brands mentioned above.

We value a diamond necklace as a complete piece of jewellery, while also assessing its individual components. Unlike a single diamond ring, a necklace can contain dozens or hundreds of stones, articulated links, a complex clasp and detachable elements.

Our physical appraisal may include:

– Total diamond weight and the approximate size range of the stones.
– The type of diamonds.
– Whether stones are uniform, graduated, matched in colour and clarity, or deliberately varied.
– The quality of principal diamonds, particularly centre stones, pendants and larger terminal drops.
– The metal, hallmarks, chain construction and overall weight.
– The clasp, safety catch, tongue, box clasp, concealed fitting and any additional security chain.
– Whether a pendant, drop, brooch or central motif is detachable.
– Brand signature, period, workmanship and original components.
– Condition of links, stone settings, hinges, solder joins and repair history.
– GIA reports, purchase receipts, previous auction records and certificates.
– Recent comparable sales for similar necklaces, not simply jewellery with the same total diamond weight.

For a rivière, we examine the graduation carefully. A well-proportioned progression from the centre to the clasp, with diamonds matched in colour and make, generally has stronger commercial appeal than a line necklace with irregular spacing, noticeably mismatched stones or later replacements.

The amount available depends on the assessed resale value of the complete necklace.

For a diamond necklace, we consider whether it is:

– A single-stone pendant necklace.
– A rivière or line necklace with graduated or uniform diamonds.
– A collar, fringe, festoon, bib, collarette or articulated diamond necklace.
– A diamond necklace with a detachable pendant, brooch conversion or removable centre stone.
– A signed modern necklace, antique piece, Art Deco jewel or vintage design.
– A necklace combining diamonds with pearls, sapphires, emeralds, rubies or other gemstones.

A higher loan amount may be possible where the necklace has high-quality natural diamonds, an established maker, secure original construction, clear certificates and a strong resale market.

We encourage early repayment and do not charge penalties for the privilege. This flexibility allows you to reclaim your diamond necklace on your terms.

Our standard loan term is seven months, but we offer flexibility to suit individual needs. Discuss your preferred duration with our team at our New Bond Street location.

In the event of non-repayment, we may sell your necklace to recover the loan amount. However, we understand that life doesn’t always go to plan, and we will do our best to avoid this scenario.

Yes, loan renewals are possible. We’ll reassess the necklace’s value and current market conditions and offer you updated terms on your control.

We don’t accept found items. To pawn a necklace at our Mayfair location, you must demonstrate legal ownership.

We consider damaged necklaces on a case-by-case basis. Minor damage may not significantly affect the loan value, but severe damage could impact our ability to offer finance.

Our experienced team in Central London is skilled in authenticating diamond necklaces. We use various techniques and tools to verify the authenticity of both the diamonds and the brand, ensuring we only offer loans on genuine pieces.

They can, provided the necklace is authentic, complete, well preserved and commercially desirable.

For signed necklaces, we check:

– Maker’s signature, serial number, hallmarks and assay marks.
– Whether the chain, clasp, pendant and any detachable components are original to the piece.
– The specific collection, design period and recognisable house style.
– Original box, certificate, purchase invoice, service documents and repair history.
– The condition of the maker’s marks, particularly after resizing, alteration or repair.
– Whether the necklace has been converted from another jewel, such as a brooch, tiara fitting or detachable pendant.

A branded necklace is not automatically worth more than an unbranded one. A classic diamond rivière with well-matched high-grade natural diamonds may support a stronger loan than a signed necklace with small, lower-quality stones or substantial condition issues.

Yes. The chain and clasp are central to a diamond necklace’s wearability, condition and resale value.

We inspect:

– Whether the chain is original to the pendant or necklace.
– The metal type, purity, hallmarks and signs of replacement or alteration.
– Solder joints, links, hinges and articulated sections for stretching, distortion or repair.
– The clasp’s function, alignment and security.
– Safety catches, safety chains, figure-of-eight catches and concealed fastenings.
– Whether the diamond-set clasp is original, complete and working properly.
– Whether the necklace has been shortened, lengthened or reconfigured.
– Signs that diamonds, links or decorative elements have been replaced.

For a pendant necklace, a later replacement chain is not always a major issue. However, for a signed diamond rivière or antique articulated necklace, an altered clasp, missing safety catch or non-original extension can materially affect both collector appeal and loan value.

Yes. We can consider antique and vintage diamond necklaces, including Victorian, Edwardian, Belle Époque, Art Nouveau, Art Deco, mid-century and later 20th-century designs.

With older necklaces, we look beyond the headline diamond weight. Their value can depend on period craftsmanship, original construction, historic diamond cuts, provenance and whether the necklace survives in an unaltered and wearable form.

We assess:

– The period, style and quality of workmanship.
– Whether old-cut, old European, rose-cut, mine-cut or single-cut diamonds are original to the necklace.
– The condition of fine knife-edge settings, platinum millegrain work, old links and delicate clasps.
– Whether the piece has been shortened, converted or rebuilt.
– Any period maker’s marks, retailer marks, original fitted case or family provenance.
– Whether repairs are sympathetic and professionally executed.

An antique necklace does not need to be untouched to be lendable. Sensible, stable restoration can be acceptable, especially in a wearable jewel. But missing original elements, heavily replaced diamonds, weakened links or major conversion work can reduce the loan offer.

Yes. We can consider both single-stone diamond pendants and multi-stone necklaces, although the appraisal approach differs.

For a single-stone pendant, the central diamond usually drives the value. We focus on its carat weight, cut, colour, clarity, natural origin, certification and setting. A detachable pendant with a GIA-certified diamond can be particularly straightforward to assess, provided the necklace and fitting are secure.

For a multi-stone necklace, we assess the overall composition as well as the principal stones. Important questions include:

– Are the diamonds well matched in colour, clarity, cut and fluorescence?
– Are the stones evenly graduated and correctly positioned?
– Are there obvious later replacements or stones that do not match the rest?
– Are all links, settings and articulated sections present and secure?
– Is the total diamond weight supported by previous paperwork or is it an estimate?
– Does the necklace have a recognised design, period or maker?

Yes. Certificates, invoices, brand paperwork and previous auction records can make a diamond-necklace appraisal faster and more reliable. They help establish gemstone quality, authenticity, ownership history and the completeness of the piece.

Useful documents include:

– GIA reports for principal diamonds, pendant diamonds or larger stones within the necklace.
– Diamond grading reports for a matched suite of larger diamonds.
– Original invoice, receipt or insurance schedule.
– Brand certificate, guarantee card, service record or repair documentation.
– Original box, fitted case, pouch and presentation material.
– Previous auction catalogue entries and published provenance.
– Documentation confirming total diamond weight, particularly for a rivière or full diamond line.

For a necklace containing many small diamonds, individual laboratory reports may not exist or be practical. In those cases, the physical appraisal, construction, diamond quality, total estimated weight and market comparables become more important. For a necklace with one major diamond, a report can be central to the valuation.

Yes. Once a loan is agreed, your diamond necklace is securely stored for the duration of the active agreement. It is not displayed, worn, loaned or sold while the agreement remains active and you remain within its terms.

Necklaces require specific handling and storage because chains, articulated links, pendants and clasps can tangle, catch or become damaged if stored carelessly. We keep the necklace protected and complete, including its detachable pendant, safety chain, clasp components, certificates, box and associated documents.

Your jewellery is protected through:

– Restricted access for authorised personnel only.
– 24-hour surveillance and alarm systems.
– Secure storage and careful handling for articulated jewellery.
– Separate retention of all accompanying certificates, fitted cases and removable components.
– No credit check is required. The loan is secured against the necklace itself, so making an enquiry does not affect your credit rating.
