Choosing a diamond ring is not about following a formula. Often, it comes down to something more instinctive.
The way a diamond catches your eye. How it feels when you see it on the hand. The balance of the design, the presence of the stone, and how naturally it fits into your life. These are the details that turn a diamond from something you admire into something that feels truly yours.
Choosing a diamond is a special experience, and we believe it should be enjoyed.
Our diamond specialists are here to help you understand what really matters, from the 4Cs and diamond quality to finding the stone that simply feels right.
With generations of jewellery expertise behind us, you can take your time, ask questions and enjoy choosing a diamond with complete confidence.
Each diamond shape reflects a unique style and personality, playing a key role in how a diamond ring or engagement ring looks and feels when worn. From the timeless brilliance of a round brilliant diamond to the clean, modern lines of an emerald cut diamond, every shape carries its own character.
Whether you’re drawn to vintage-inspired diamond rings or prefer a more contemporary diamond design, exploring different diamond shapes helps you find something that feels truly personal.
At Lister Horsfall, we offer a carefully curated selection of high-quality diamonds, chosen to suit a range of styles while maintaining the highest standards of craftsmanship and beauty.
The round brilliant diamond is often the one people fall in love with first. It’s designed to catch the light beautifully, giving it that unmistakable sparkle you notice straight away.
It’s a natural choice for an engagement ring, simply because it works with almost everything - classic, modern, or something in between.
A little detail we love sharing: it’s made up of 58 facets and is the only diamond shape cut to very precise proportions to bring out as much light as possible.
The princess cut diamond is known for its clean lines, sharp corners, and contemporary feel. With its square or slightly rectangular shape and brilliant faceting, it offers a beautiful balance of modern sophistication and sparkle.
It’s often chosen by those looking for something a little bolder, while still holding onto the fire and brilliance you’d expect from a classic diamond. There’s a confidence to it - structured, refined, but never overstated.
It also sits neatly within a diamond ring, giving a crisp, elegant finish that works beautifully across both modern and more classic settings.
A little detail we often share: the princess cut is designed to retain more of the original diamond, meaning less is lost during cutting - something that can make a real difference when balancing size and value.
The oval diamond has a soft elegance to it. It carries the sparkle of a round diamond, but with a more elongated shape that feels slightly more distinctive.
It’s often chosen for how it sits on the hand - creating a gentle lengthening effect that feels refined without being overstated. There’s a natural balance to it, making it just as suited to a classic engagement ring as it is to something more contemporary.
A little detail we often share: because of its shape, an oval diamond can appear larger than its carat weight, giving a little more presence without increasing size.
The cushion cut diamond has a softer, more romantic feel. With its rounded corners and gentle shape, it carries a sense of warmth that feels both timeless and easy to wear.
There’s something slightly nostalgic about it too - often chosen for vintage-inspired engagement rings, yet just as beautiful in more modern designs. Its sparkle is a little more subtle, creating a softer glow rather than a sharp brilliance.
A little detail we often share: the cushion cut has been around for over 200 years, making it one of the oldest diamond shapes still loved today.
When choosing a diamond, confidence should come naturally.
That’s why we recommend GIA certified diamonds, assessed by the Gemological Institute of America - widely regarded as one of the most respected and consistent authorities in diamond grading worldwide.
A diamond certificate provides an independent and unbiased assessment of a diamond’s quality, detailing its cut, colour, clarity and carat weight, along with additional characteristics such as proportions and fluorescence. Each diamond is carefully examined under controlled conditions, ensuring accuracy and consistency across every grading report.
More than just documentation, certification offers clarity and reassurance - allowing you to understand exactly what you are choosing, and why it matters.
Today, choosing a diamond comes with more considered options than ever before.
Natural diamonds are formed deep within the earth over billions of years, shaped by time, pressure, and nature. Each one is entirely unique, carrying a rarity and sense of permanence that has long been associated with life’s most meaningful moments.
Lab-grown diamonds are created using advanced technology that replicates these natural conditions. They share the same physical and visual properties as natural diamonds and are graded using the same 4Cs.
While they appear similar, their origins are very different — and for many, that distinction plays an important part in the decision.
Both options offer their own appeal. Whether you are drawn to the natural rarity of a diamond formed over time, or prefer a more contemporary approach, we are here to guide you through the differences with clarity, care, and honesty.
For us, true luxury is not only about how something looks, but where it comes from.
We are committed to sourcing ethical diamonds with care, working only with trusted partners who share our standards of responsibility. All of our diamonds comply with the Kimberley Process Certification Scheme, helping to ensure they are conflict-free and responsibly sourced.
But for us, it goes beyond certification.
We place real importance on understanding where our diamonds come from. By working closely with long-standing suppliers, we’re able to select high-quality diamonds with confidence - not only for their beauty, but for the integrity behind them.
Responsible sourcing isn’t something we add on. It’s part of how we choose every diamond engagement ring and piece of fine jewellery, ensuring each one reflects the same level of care behind the scenes as it does in its craftsmanship.
As a family-run jeweller with over 120 years of heritage, this is simply part of who we are - offering reassurance that every diamond chosen at Lister Horsfall carries a standard of responsibility you can feel confident in.
Choosing a diamond should feel exciting, personal and never rushed. At Lister Horsfall, we take the time to understand what matters to you, answer your questions and guide you through the details at your own pace.
With generations of diamond and jewellery expertise behind us, you can expect knowledgeable, honest advice and a personal approach — helping you choose with confidence and enjoy the experience along the way.
