Diamonds and Jewellery We Buy
A quick overview of the diamond jewellery we consider at our Church Street counter:
Subject to inspection and the characteristics of the item.
Selling a Diamond Ring?
- • Engagement, wedding, eternity and dress rings may all be assessed.
- • The diamond and the metal setting may both contribute to the value.
- • Brand, design and condition can sometimes matter.
- • Please bring boxes, receipts and certificates where available.
- • Paperwork can help but isn’t always essential.
- • Please don’t remove the stone or alter the ring before visiting.
“We explain what we have considered before you decide whether to sell.”
What Can Affect the Value of a Diamond?
- • Carat weight
- • Cut
- • Colour
- • Clarity
- • Shape
- • Whether the diamond is natural or laboratory-grown
- • Certification
- • Condition
- • Current resale demand
- • The gold or platinum setting
- • Brand or design, where relevant
The 4Cs (carat, cut, colour and clarity) help describe a diamond, but they don’t automatically determine what a buyer can offer. Resale demand, condition and the setting all come into it.
Have a Diamond Certificate?
- • GIA, IGI and other recognised reports can be helpful.
- • Please bring the certificate with the item.
- • The certificate details must match the diamond.
- • Receipts and previous valuations may provide useful background.
- • An insurance valuation isn’t the same as a realistic resale value.
- • You can still enquire if the paperwork has been lost.
Natural or Lab-Grown Diamond?
- • Natural and laboratory-grown diamonds are different markets.
- • Their resale demand and values can differ substantially.
- • The stone needs to be identified before an offer can be considered.
- • Certificates and purchase documents can help.
We can inspect the item and explain whether it is something we are able to make an offer on.
Diamond Jewellery in Gold or Platinum
- • The precious-metal setting can contribute to the value.
- • Gold purity may need to be checked.
- • Platinum may be assessed separately.
- • The full scale weight can’t automatically be treated as precious-metal weight.
- • Stones and non-metal components must be considered.
- • Some jewellery may have value as a complete piece rather than only for materials.
Selling other gold jewellery too? See our gold jewellery page.
Inherited Diamond Jewellery?
- • You don’t need to identify or catalogue everything yourself.
- • Photographs can be sent before visiting.
- • Keep boxes, certificates, receipts and old valuations together.
- • Individual items and collections may both be considered.
- • Larger collections can be discussed before visiting.
- • Please don’t clean, reset or dismantle anything beforehand.
How We Assess Diamond Jewellery
The assessment may consider:
- • The diamond or stones
- • Whether the stone is natural or laboratory-grown
- • Carat weight
- • Cut, colour and clarity
- • Shape and condition
- • Certificates
- • The gold or platinum setting
- • Brand and design, where relevant
- • Current resale demand
We explain how we reached the offer before you decide whether to sell. See how it works or read our valuation guide.
Already Had a Quote for Your Diamond?
Send us the written quote and clear photographs of the same item. Let us try to beat any genuine like-for-like offer before you sell.
A fair comparison needs to relate to the same item, the same diamond or stones, the same precious-metal setting and comparable payment and sale conditions.
What Photos Should I Send?
Where possible, please send:
- • A full photograph of the item
- • Front, back and side views
- • A close-up of the diamond
- • The hallmark
- • Any certificate
- • The box or packaging
- • Any existing written quotation
Not sure what details matter? Send clear photographs and we’ll take a look.
Photographs give an initial indication only — a final offer is confirmed after physical inspection.
Frequently Asked Questions
Do you buy diamond engagement rings?
Yes — engagement, wedding, eternity and dress rings are all welcome. Send us clear photos on WhatsApp or bring the ring to our Church Street shop.
Do you buy loose diamonds?
Loose stones are considered subject to inspection and the characteristics of the diamond. Please send photos and any certificate first so we can let you know before you travel.
Do I need a certificate?
No — a certificate isn't essential. GIA, IGI or similar reports can be helpful where they match the item, but many pieces are assessed without one.
Can you value a diamond from photographs?
Photographs help us understand what you have and give an initial idea. A final offer is confirmed after seeing and checking the item in person.
Do you buy laboratory-grown diamonds?
Natural and laboratory-grown diamonds are different markets with different resale demand. We can inspect the item and explain whether it is something we are able to make an offer on.
Does the gold or platinum setting have value?
Yes — the precious-metal setting can contribute to the value. Gold purity and platinum are assessed separately, and stones and non-metal components are considered.
Is an insurance valuation the same as resale value?
No. An insurance valuation reflects a replacement figure and is usually higher than a realistic resale value. We explain how the offer is reached before you decide whether to sell.
Do you buy damaged diamond jewellery?
Damaged pieces are welcome. Please don't try to repair, reset or dismantle anything beforehand — bring it as it is.
Do you buy inherited diamond jewellery?
Yes. Individual items and collections can be considered. You don't need to identify or catalogue anything yourself — bring it as it is with any boxes, receipts or old valuations.
Can you try to beat an existing quote?
Send us the written quote and clear photographs of the same item and we'll try to beat any genuine like-for-like offer. We can't guarantee to beat every quote, but we'll always take a look.
Do I need identification?
Yes. Please bring valid photo ID (passport or driving licence) when you visit — it's a standard requirement for second-hand jewellery purchases.
How quickly can I be paid?
Same-day payment is available in most cases, once we've seen the item in person and agreed a final offer.
Do I need an appointment?
No appointment is needed for individual pieces. For larger collections or higher-value items it's worth calling ahead so we can make time to go through everything properly.
