Introduction

If you are considering selling a treasured piece of jewellery—perhaps an inherited diamond ring, an old watch, or unused gold—the process can feel overwhelming. Where do you start? What is it worth? And crucially, what documents do you need to ensure a secure, legal, and profitable sale?

For sellers in London, the historical Hatton Garden district is the ultimate destination for securing the best price. To make your first visit efficient and successful, being prepared is key. This guide outlines exactly what to bring when selling jewellery in London to guarantee a smooth and highly rewarding experience.

Category 1: Mandatory Legal Requirements

Reputable jewellery buyers, particularly those operating in established centres like Hatton Garden, must adhere to strict Anti-Money Laundering (AML) regulations set by the UK government. This diligence protects both the buyer and the seller and is non-negotiable for a professional transaction.

·         1. Photographic ID: You must bring a current, valid form of photographic identification. This is required to prove you are the legal owner making the sale.

o    Examples: Valid Passport, Full UK Driving Licence, or National ID Card.

·         2. Proof of Address: You will also need documentation to confirm your current residential address, typically issued within the last three months.

o    Examples: Utility Bill (not a mobile phone bill), Bank Statement, or Council Tax Bill.

Crucial Note: Reputable buyers will keep a record of these documents for their legal compliance files (typically for five years). Never sell to a dealer who does not ask for ID, as this signals a disregard for legal standards.

Category 2: Documents to Maximise Your Price

While the legal documents ensure the transaction is secure, these items are vital for establishing the value of your jewellery, often leading to a significantly higher final offer:

·         1. Gemmological Certificates: If your item features a significant stone, especially a diamond, the GIA (Gemological Institute of America) or IGI (International Gemological Institute) certificate is the single most important document. This independent report details the 4 Cs (Carat, Cut, Colour, Clarity), saving the buyer time and cost on re-certification, which translates directly into a higher price for you.

·         2. Original Receipts or Invoices: The original proof of purchase or sales invoice establishes the provenance (history of ownership) and can act as unofficial proof of authenticity, particularly for branded or antique pieces.

·         3. Previous Appraisals or Valuations: While an insurance valuation often exceeds the resale market value, providing an older appraisal gives the buyer essential information about the item's specifications, age, and condition at the time the appraisal was conducted.

·         4. Original Box and Packaging: For high-end luxury items (e.g., Cartier, Tiffany & Co., Rolex), the original box, outer packaging, and papers (such as service history for a watch) significantly enhance the resale value, as collectors desire a complete set.

Category 3: The Jewellery Itself

Prepare your jewellery for its free valuation by following these simple steps:

·         1. Clean and Detangle: While professional buyers will assess the metal purity and stone quality regardless of condition, presenting a clean, detangled piece (especially chains) makes the initial inspection faster and more pleasant.

·         2. Check for Hallmarks: Look for small stamps on the inside of rings, on the clasp of necklaces, or the back of earrings. These UK hallmarks indicate the metal and purity (e.g., '750' for 18ct gold, '925' for sterling silver) and provide instant confirmation of content.

Summary

For a first-time seller seeking to sell jewellery in London, preparation is the key to maximising your cash offer. You must bring Photo ID and Proof of Address for legal compliance. To maximise your valuation, gather any GIA/IGI certificates, original receipts, and boxes. By visiting a professional buyer in Hatton Garden, you ensure a transparent, secure, and competitive transaction based on a free valuation.

FAQs

Q: Do I need a GIA certificate to sell my diamond ring?

A: No, you can sell a diamond ring without a certificate, but the buyer will need to have it professionally appraised in-house. Having a GIA certificate provides immediate, trusted third-party verification, which nearly always results in a higher and faster offer.

Q: What if I can't find my old receipt?

A: Don't worry. While helpful, the receipt is not mandatory. The most important factor is the item's intrinsic value (metal and stones), which will be determined by a professional jewellery appraisal during your visit.

Q: Is it safe to sell jewellery in Hatton Garden?

A: Yes. Hatton Garden is the historical centre of the UK jewellery trade. Reputable dealers follow strict legal protocols, require ID, and provide secure, traceable payment (usually instant bank transfer), making it the safest place to sell jewellery in London.

Q: Do you offer a free valuation?

A: Yes, all professional buyers in Hatton Garden, including our store, offer a complimentary, no-obligation free valuation of your jewellery items based on current market prices.
