When people search for moissanite diamond engagement rings, they are looking for something specific: a ring that delivers the full visual impact of a diamond at a price that actually makes sense.
That is precisely what this collection from Franc Laurent is built around. These are not simple solitaires, they are full set designs, meaning each ring features a significant centre stone paired with carefully matched side stone accents, creating a complete, cohesive look that reads as genuinely luxurious on the hand.
Every ring in this collection carries a 2.00ct centre stone and 1.00ct of side stone accents, totalling 3.00ct of D/E colour, FL/VVS clarity moissanite per ring. For context, a 3ct natural diamond ring of equivalent quality would cost tens of thousands of pounds. Here, that same on-hand impact is achieved for a fraction of that, without compromising on brilliance, cut, or craftsmanship.
What Is a Full Set Moissanite Ring and Why It Looks More Expensive
A full set engagement ring refers to a design where the centre stone is accompanied by accent stones that are set directly into the band or shoulders, creating a unified, jewellery-store look rather than a single stone sitting alone. The key distinction between a full set ring and a simple solitaire is presence.
A full set design has coverage, the stones flow from the centre outward, making the entire ring sparkle rather than just the single stone at the top. This makes the ring appear larger, more complex, and more premium even at comparable carat weights. In terms of moissanite specifically, the full set design amplifies what moissanite already does best: producing high-intensity brilliance and fire across every facet.
When centre stone accents and side stones are all cut to the same D/E colour and FL/VVS clarity standard, as they are across all Franc Laurent rings, the light performance across the full ring is consistent and cohesive, with no visible difference in colour or quality between the main stone and the accents.
The result is a ring that looks considered, coordinated, and definitively high-end.
Why Moissanite Outperforms Diamond in a Full Set Design
In a full set ring, the stone's light performance matters across every single stone on the band, not just the centre. This is where moissanite's technical superiority over natural diamonds becomes most visible.
Moissanite has a refractive index of 2.65, compared to a diamond's 2.42. In practical terms, this means moissanite bends and reflects light more intensely, producing more fire, those rainbow flashes of colour, and more brilliance, white light return, per facet. In a full set design with multiple stones, this means the entire ring actively sparkles from every angle, not just when light hits the centre stone directly.
Natural diamonds at equivalent price points cannot match this level of light performance. Lab-grown diamonds are closer in chemical composition to natural diamonds but still sit below moissanite's refractive index. On top of optical performance, moissanite scores 9.25 on the Mohs hardness scale, making it the second hardest gemstone used in jewellery after diamond, and significantly harder than any other stone used in fine jewellery.
For a ring worn every single day, this durability matters enormously. Moissanite does not scratch, chip, or lose its brilliance over time, which means the ring you buy today will look identical in ten and twenty years from now.
Our Top 5 Full Set Moissanite Diamond Engagement Rings
Every ring below features a 2.00ct centre stone, 1.00ct of side stones, a 3.00ct total carat weight, D/E colour, FL/VVS clarity, excellent cut moissanite, set in sterling silver with a claw setting. Each comes with a luxury ring box, warranty card, and GRA certificate of authenticity. Starting price across the collection is £650 for 1ct centre weight options.
The Cushion Cut Moissanite Engagement Ring, Full Set is the most romantic and vintage-inspired design in the collection. The cushion cut, characterised by its rounded corners and pillow-like shape, produces a softer, warmer kind of brilliance compared to sharper cuts.
It is a shape that has been popular in fine jewellery for over a century and carries a sense of timeless prestige. With matching cushion-cut accents in the full set design, the ring has a uniform, coordinated appearance that looks genuinely complete. Starting from £650, it is the ideal choice for someone who wants old-world charm with modern moissanite brilliance.
The Round Cut Moissanite Engagement Ring, Full Set Design Style is the most universally appealing design in the collection. The round brilliant cut has 58 precisely arranged facets that are engineered to maximise light return, making it the most optically efficient cut ever developed for a gemstone.
A 2.00ct round moissanite in a full set claw setting is one of the most impressive-looking rings you can put on a finger, the centre stone commands attention while the side stones carry that brilliance continuously down the band. Starting from £650, this is the ring for someone who wants zero compromise between classic beauty and maximum sparkle.
The Cushion Cut Moissanite Engagement Ring, Elongated Full Set Design takes the cushion cut and stretches it into a longer, more rectangular silhouette. The elongated cushion occupies more visual space on the finger than a standard cushion of the same carat weight, creating a more dramatic, fashion-forward appearance that sits somewhere between the softness of a cushion and the length of an oval.
It is a cut that has grown significantly in popularity as buyers seek shapes that feel modern and distinctive rather than traditionally safe. Starting from £650, this is a strong choice for someone who wants the warmth and romance of a cushion cut with the elongating, finger-flattering effect of a longer stone.
The Emerald Cut Moissanite Engagement Ring, Full Set Design brings a completely different energy to the full set format. Where round and cushion cuts produce maximalist sparkle, the emerald cut produces a distinctive hall-of-mirrors effect, long, linear flashes of light that pulse through the stone with a cool, architectural quality.
In a full set design, the step-cut centre stone is flanked by matching accents that extend this linear brilliance across the width of the ring, creating a ring that looks bold and intelligent rather than purely glamorous. Starting from £650, this is the ring for someone with refined, editorial taste who wants her jewellery to make a statement through form as much as sparkle.
The Radiant Cut Moissanite Engagement Ring Full Set is the most versatile design in the collection, a cut that combines the best qualities of both the round brilliant and the emerald cut. The radiant cut has the rectangular or square outline of a step-cut stone but is faceted like a brilliant cut, meaning it produces intense sparkle alongside the elongated, geometric silhouette of a fancy shape.
It is a powerful combination: the visual scale of a larger-looking stone paired with the fire and brilliance of a round. In the full set design, the radiant centre stone is matched with perfectly proportioned side accents, and the total effect is one of controlled extravagance.
Starting from £650, this is the ring for someone who wants to stand out, a cut that is immediately recognisable as different, yet unmistakably elegant.
How to Choose Between These Five Full Set Designs
All five rings in this collection are built to the same exceptional quality standard and share the same total carat weight, metal, and stone grades. The decision between them is entirely about personal aesthetic preference and what the stone shape communicates on the hand.
The round cut is the most brilliance-focused and universally flattering, it suits every hand shape and every personal style. The standard cushion cut is the most romantic and vintage-inspired, ideal for someone drawn to antique or heritage jewellery aesthetics. The elongated cushion bridges the gap between the cushion's softness and the modern desire for a longer, slimmer looking stone, and is a compelling choice for someone who wears longer fingers or simply wants a more contemporary cushion profile.
The emerald cut is the most architectural and deliberate, it is a considered choice that prioritises cool elegance over fire, and it suits someone who wears her style with confidence and specificity. The radiant cut is the most dynamic, it combines the visual scale of a fancy shape with brilliant-cut faceting, making it the best option for someone who wants an unusual shape without sacrificing any light performance.
When comparing side by side, consider the hand it will live on, the other jewellery she wears, and whether her personal style leans warm and romantic or cool and modern.
Final Thoughts: Why Full Set Moissanite Is the Smartest Engagement Ring Investment
A full set moissanite engagement ring from Franc Laurent represents the most value-efficient way to buy a genuinely impressive, high-quality engagement ring available in the UK market today. For £650 upward, you receive a 3ct total weight ring in D/E colour, FL/VVS clarity moissanite, stones that are completely colourless, completely eye clean, and cut to an excellent standard, set in sterling silver with a claw setting and delivered with full GRA certification.
The same ring in natural diamond would cost anywhere from £15,000 to £40,000 or more at equivalent quality grades. Lab-grown diamond would be cheaper but would still significantly exceed the moissanite price point while producing less brilliance. Moissanite is not a compromise, it is a genuinely superior stone for anyone who prioritises light performance, ethical sourcing, durability, and value.
The full set format takes all of that and presents it in a ring design that looks complete, considered, and luxurious from every angle. This is the ring that makes people ask where it came from, and the answer will always surprise them.
