Introduction

Selling a loose diamond—one that has been removed from its setting or was purchased as an investment—requires a different level of expertise than selling standard jewellery. Without a gold or platinum mounting to provide context, the value of the stone rests entirely on its individual characteristics. If you are looking to sell loose diamonds in London, the most critical step is finding a buyer who understands the global wholesale market.

In the heart of the capital, Hatton Garden stands as the premier destination for such transactions. Here, expert gemologists use precision tools to evaluate your stone’s unique profile. Whether you have a round brilliant, a fancy pear shape, or a rare coloured diamond, knowing you are dealing with expert buyers you can trust ensures you receive the maximum market value. To start the process, you can get a free quote online or bring your stone in for a professional assessment.

Why Selling Loose Diamonds is Unique

When you sell a ring, the buyer considers the design and the metal. When you sell a loose diamond, the focus is purely on the stone’s "DNA." Professional buyers in London look for:

• The 4Cs: Carat, Colour, Clarity, and Cut. Even a slight variation in these can mean a difference of hundreds or thousands of pounds.
• Fluorescence: This hidden characteristic can either enhance or detract from a stone’s value, something only a specialist can accurately judge.
• Laser Inscriptions: Many loose stones have a serial number etched on the girdle that links to a GIA or IGI report.

Because these factors are so technical, it is vital to request an appraisal from a specialist rather than a general high-street pawnbroker.

The Hatton Garden Advantage

London’s historic jewellery quarter is the only place where you can find a high concentration of GIA-trained experts and laboratory-grade equipment in one square mile. Choosing a Hatton Garden buyer offers several benefits:

1. Competitive Bidding: Because there are many specialist buyers, they must offer the best price for loose diamonds to win your business.
2. Advanced Technology: Buyers here use X-ray machines and microscopic cameras to verify the internal characteristics of your diamond.
3. Direct Market Access: These buyers often sell directly to international cutters and collectors, allowing them to cut out the middleman and pass the savings on to you.

• Know the Shape: Some shapes, like the "Old Mine Cut" or "Emerald Cut," are currently seeing a surge in collector demand.
• Clean the Stone: A quick professional clean ensures the gemologist can see the clarity and colour without interference from dust or oils.

FAQs

Q: Can I sell a loose diamond without a certificate?

A: Yes. While a certificate from a lab like GIA helps, expert buyers in Hatton Garden have on-site gemologists who can grade your stone and provide a free valuation even without paperwork.

Q: How do you determine the price of a loose diamond?

A: The price is calculated based on the Rapaport Diamond Report (the industry standard for wholesale prices), adjusted for the stone’s specific 4Cs and current market demand in London.

Q: Is it safe to send my diamond by post for a quote?

A: Many reputable London buyers offer a secure, insured postal service. However, for high-value loose stones, we recommend you Visit Our Store Today for a secure, in-person evaluation.

Q: Do you buy "fancy coloured" loose diamonds?

A: Yes. Yellow, pink, and blue diamonds are highly sought after. Because these are rarer than white diamonds, they require a specialist appraisal to determine their true "fancy" grade and value.

Q: Will I get paid the same day?

A: Yes. Once the stone is verified and the offer is accepted, most Hatton Garden buyers provide immediate payment via secure bank transfer or cash (subject to legal limits). Get a free quote today to start the process.
