Guides

Choosing an engagement ring is one of the more consequential purchases most people will make, and yet very few buyers go into it with a clear understanding of what actually separates a well-made ring from an expensive one. This guide exists to close that gap.
We designed it as a reference, not a sales pitch. You’ll find the same information here that we’d walk you through in a private consultation: how to think about diamond shape, what setting styles actually do, where lab-grown diamonds fit into the picture and how to spend well rather than simply spend more.
Where a topic deserves more depth than a single page allows, we’ve linked to a dedicated guide.

There are four decisions that shape every engagement ring: the diamond shape, the setting style, the metal, and the carat weight. Each one affects the others — a heavier stone needs a setting that can support it, a delicate band reads differently in yellow gold than in platinum, and so on. Most buyers make these decisions in the wrong order, starting with carat weight and working backwards. We’d suggest starting with shape and setting, since those determine how the ring will actually look and wear day to day, then use metal and carat to fine-tune the result within your budget.
It’s worth deciding early whether you’re buying for someone else or choosing together. If you’re buying alone, focus on what suits their hand, their existing jewellery, and how they dress day to day, rather than what’s currently trending. A ring is worn for decades; a trend has a shelf life of a few years.

The shape of the centre stone has more impact on the ring’s character than almost any other decision.
Round brilliant. The most classic and most efficient cut for sparkle, thanks to its symmetrical facet structure. It suits almost any setting and any hand shape, which is why it remains the most commonly chosen shape. It’s also typically the most expensive per carat, since more of the rough diamond is cut away in the shaping process.
Oval. An elongated alternative to round with nearly the same brilliance, but with the visual effect of elongating the finger. A popular choice for buyers who want the classic sparkle without the classic shape.
Emerald and radiant cuts. Step-cut stones that prioritise clarity and light over sparkle — think glass-like transparency rather than fire. These shapes show inclusions more visibly than brilliant cuts, so clarity grade matters more here than elsewhere.
Cushion cut. A softened square with rounded corners, sitting between the classic (round) and the architectural (emerald). Currently seeing a strong resurgence, particularly in antique-inspired “old mine cut” styles.
Pear and marquise. Elongated, tapered shapes that read as more distinctive and less traditional. Both suit a hand that wants a ring with presence without excessive size.
We go into shape selection in more depth, including how each one performs at different carat weights, in our [Diamond Shape Guide].

The setting does two jobs: it determines how much the stone is protected day to day, and it defines the overall silhouette of the ring.
Solitaire. A single stone, usually raised on prongs. The most enduring and most flexible style — it photographs well, wears well, and doesn’t compete with the diamond for attention. Still the most-chosen style by a wide margin.
Halo. A centre stone encircled by smaller accent diamonds, which increases the apparent size of the centre stone and adds overall sparkle. Better suited to those who want maximum visual impact from a smaller carat weight.
Trilogy (three-stone). A centre stone flanked by two smaller stones, often used to symbolise past, present, and future. A strong choice for those who want more presence than a solitaire without the density of a halo.
Pavé and diamond band. Smaller diamonds set continuously along the band itself. This has been one of the fastest-growing styles recently, as couples move towards more decorative, statement-led designs that still read as timeless rather than trend-led.
Vintage-inspired settings. Milgrain detailing, filigree work, and antique-style claws borrowed from Georgian and Art Deco design. These settings have seen a significant rise in interest as buyers move away from purely trend-driven pieces towards ones that feel personal and built to last.

A lab-grown diamond is chemically, physically, and optically identical to a mined diamond — the difference is entirely in origin, not composition. It is grown under controlled conditions that replicate the pressure and heat that forms diamonds naturally, rather than being extracted from the ground.
The practical effect of this is cost. Lab-grown diamonds typically cost significantly less than a mined diamond of equivalent size and quality, which means buyers can choose a larger stone, a higher clarity grade, or put the difference towards a more considered setting — without stretching the budget.
This is not a fringe choice. Lab-grown diamonds now represent a substantial and growing majority of the UK engagement ring market, and that share has continued to climb as more buyers understand there is no difference in appearance, durability, or long-term value between a well-made lab-grown ring and its mined equivalent.
If you’re deciding between the two, our [Lab-Grown vs Natural Diamonds guide] covers grading standards, resale considerations, and how to read a diamond certificate either way.

There is no fixed rule here, despite how often one is quoted. The “months of salary” guideline is a relic of diamond industry marketing, not a meaningful benchmark for how any individual couple should budget.
A more useful approach: decide what you can spend without financial strain and then use lab-grown diamonds, careful metal choice and a well chosen setting to get the most ring for that number, rather than the largest carat weight possible. A smaller, well-cut, well-set stone consistently looks better than a larger one with poor cut or a weak setting.
Our full breakdown of realistic UK spending ranges and what changes at each price tier, is available in [How Much Should You Spend on an Engagement Ring?].

Ring sizing is the most commonly rushed part of the process, and the easiest to get wrong when buying as a surprise. A ring that’s slightly large is a quick, inexpensive resize; a ring that’s too small can be more complicated, particularly with pavé or eternity-style bands where the stones continue around the shank.
If you’re buying without being able to ask directly, there are reliable ways to estimate size using an existing ring or basic measurements. We cover this in detail in our [Ring Sizing Guide], including what to do if you get it wrong.

If you already know roughly what you want, our full collection is organised by shape, setting, and metal, so you can move straight to browsing.
If you’d rather talk it through — particularly if you’re buying as a surprise, or deciding between lab-grown and natural, or simply want a second opinion before committing — we offer free, no-obligation consultations. This is not a sales call; it’s the same conversation we’d have in person, just remote.
