Why buy your jewellery from Charles Fish?
Outstanding value, carefully selected pieces and generations of jewellery knowledge — all with the reassurance of a family-run business that has been doing this since 1830.
Our approach
At Charles Fish, we’re passionate about bringing outstanding value to the high street.
We’re committed to providing quality and pricing that stands up against the competition. We’ve been in the fine jewellery business since 1830, so you can rely on the expertise of our family-run business and trust that finding the right piece for you is our priority.
We design collections in-house and work with skilled craftspeople to create beautiful jewellery, while our pre-owned collection gives us another way to offer remarkable pieces at compelling prices.

Why Charles Fish?
Expertise behind every piece
Whether you’re buying a diamond ring, discovering a pre-owned icon or looking for something completely individual, the details matter.
Hand-selected diamonds
Our experts consider more than the headline colour and clarity grades. Proportion, cut, visual character and millimetre spread all contribute to how a diamond actually looks once worn.
Quality over paperwork alone
Certification matters, but it is only part of the story. We reject stones that do not meet our expectations for beauty, including poorly proportioned diamonds and stones with undesirable milky characteristics or severe fluorescence.
Competitive pricing
Our approach has always been to combine strong value with jewellery we would be happy to recommend ourselves, rather than treating price and quality as separate considerations.
Almost two centuries of experience
Since 1830, generations of jewellery knowledge have shaped the way we buy, assess and present pieces — from contemporary diamond rings to pre-owned jewellery and watches.
What we look for
It goes beyond the four Cs
A certificate can tell you a great deal about a diamond, but it cannot replace an experienced eye. Correct dimensions and proportion matter just as much as attractive colour and clarity grades.
- A 0.50ct round brilliant cut diamond should measure around 5mm across, and spread is one of the details we consider when selecting stones.
- We look for diamonds with strong visual performance rather than simply choosing a stone because its certificate appears attractive on paper.
- We favour very good or excellent cut grades and reject stones that do not meet our expectations for overall appearance.
The fifth C
Certification
Our certified diamonds are accompanied by reports from respected laboratories such as the GIA and IGI. Independent grading gives you clearer information about the characteristics of the stone and another layer of reassurance when making an important purchase.
A modern example of value
Luxury does not always have to begin with buying new
Pre-owned jewellery allows us to offer iconic pieces with their design, craftsmanship and character already established — often at a compelling point of entry compared with purchasing a comparable piece new.

Pre-Owned 18ct White Gold Cartier LOVE Bangle 17
A particularly good example of how pre-owned can combine recognised design with strong value is this 18ct white gold Cartier LOVE bangle. First introduced in 1969 and designed by Aldo Cipullo, the LOVE bracelet has become one of Cartier’s most recognisable jewellery designs.
This pre-owned example has an inner circumference of 17cm, measures 6.00mm in width and weighs 33.50 grams. It is supplied with its screwdriver, Cartier inner and outer boxes, full hallmarking and a certificate of authenticity.
