The Asscher cut was created in 1902 by the Royal Asscher Diamond Company — a square step-cut with deeply cropped corners and a series of concentric rectangular facets that produce the famous "hall-of-mirrors" or windmill effect. Unlike brilliant cuts that scatter light in every direction, the Asscher's step facets create broad flashes of light and shadow — a more deliberate, architectural sparkle. It suits wearers who want a diamond that looks distinct from every other ring in the room. Our lab-grown CVD Asscher diamonds are held in a classic four-prong solitaire that lifts the stone high enough for light to enter from all four sides, fully activating the step-cut geometry.

4 Prong Asscher Cut Solitaire Diamond Ring

The Asscher cut stands in a category of its own. Where most modern engagement rings compete on brilliance — on scatter and flash — the Asscher offers something rarer: depth. Its square step-cut facets create the iconic windmill pattern, a series of concentric squares that draw the eye into the centre of the stone rather than bouncing light outward. The result is a ring that looks completely different from every other solitaire on the market.

Set in a clean four-prong solitaire mount in your choice of 18K white, yellow or rose gold, the Asscher sits elevated above the band — allowing light to enter the stone from the sides and fully animate the step-cut geometry. The prongs are slim and recessed, keeping the stone the undisputed focus of the design. Available in 0.50ct to 1.50ct, each diamond is D–E colour and VVS/VS clarity — the step-cut shows inclusions more readily than brilliant cuts, which is why we hold our Asscher stones to the highest clarity standards.

Lab-grown CVD Asscher diamonds give you 60–70% more stone for your budget than mined equivalents, with the same optical properties and full IGI certification to confirm it.

Why clarity matters especially for Asscher cuts. Step-cut diamonds like the Asscher are highly transparent — light passes through the stone rather than being scattered. This means any inclusion is more visible to the naked eye than in a brilliant cut. We only offer Asscher diamonds at VVS/VS clarity to ensure the stone is eye-clean and the interior hall-of-mirrors effect is uninterrupted. The IGI certificate confirms this independently.

Caring for Your Asscher Cut Solitaire Ring

The Asscher cut's large, flat step facets are beautiful — and they also show oil, fingerprints and smudges more readily than brilliant cuts. A simple monthly cleaning keeps it looking immaculate.

Cleaning at Home: Soak in warm water with a small drop of mild dish soap for two minutes. Use a soft toothbrush to gently clean around the stone and the four prongs. Rinse thoroughly and pat dry with a lint-free cloth. The step facets will be visibly cleaner after even one cleaning — the difference is dramatic.

Daily Wear: Remove before swimming, applying perfume, moisturiser or hairspray. Remove before sleep to prevent the prongs from catching on bedding. The four prong setting is secure for daily wear — we recommend a professional prong inspection every 12 months to confirm all prongs are tight.

Storage: Store the ring in the presentation box or a soft fabric pouch. The Asscher cut's corners, though cropped, can chip if knocked against a hard surface — store separately from other jewellery.

Why This Ring

The Asscher, Elevated

Every detail of the Asscher Cut Solitaire Ring is chosen for the woman who wants a ring that says something different.

Asscher Step-Cut Diamond

The iconic square step-cut creates a hall-of-mirrors effect — broad, architectural flashes of light rather than scattered brilliance. A stone that rewards close attention and draws the eye inward rather than outward.

Four Prong Solitaire

Four slim prongs at the cardinal points of the square diamond hold it elevated above the band, maximising light entry through the sides and fully activating the step-cut geometry from every angle.

IGI Certified · VVS/VS

Step-cut diamonds show clarity characteristics more readily than brilliant cuts. We only offer our Asscher in VVS/VS grades — confirmed by the IGI — ensuring the interior of the stone is eye-clean and uninterrupted.

18K Gold · Your Metal

Available in white, yellow or rose gold (750 — 75% pure). White gold emphasises the Asscher's cool geometric lines; yellow gold warms the stone; rose gold adds a romantic softness to the angular cut.

Questions

Frequently Asked

Everything you need to know about the Asscher Cut Solitaire Ring before you buy.

The Asscher is a square step-cut — its facets run in parallel rows rather than radiating from a central point. This creates the famous "hall-of-mirrors" or windmill pattern: a series of concentric squares that draw the eye into the depth of the stone. Unlike brilliant cuts (round, oval, pear) which scatter light in all directions, the Asscher creates broad, dramatic flashes of light and deep shadow — a more measured, architectural sparkle. It was the diamond of the Art Deco era and suits geometric, vintage and minimalist styles equally.

Step-cut diamonds like the Asscher are optically transparent — light passes straight through the stone in broad beams rather than being scattered by multiple facets. This means inclusions are more visible to the naked eye than in a brilliant cut. A VS1 inclusion that would be invisible in a round brilliant can be noticeable in an Asscher. We only offer Asscher diamonds at VVS/VS clarity to guarantee an eye-clean stone — confirmed independently by the IGI grading certificate included with every ring.

Yes — completely real. Lab-grown CVD diamonds are chemically, optically and physically identical to mined diamonds. Both are pure carbon in the same crystal lattice structure. The only difference is origin: mined diamonds form underground over billions of years; ours are grown in a controlled chamber in 6–10 weeks. No gemologist can distinguish them by sight or instrument. They are graded by the IGI to exactly the same standards applied to mined diamonds — the certificate confirms carat, colour, clarity and cut independently.

EU ring sizes correspond to the inner circumference of the ring in millimetres. To measure at home, wrap a thin strip of paper around your finger, mark where it overlaps, and measure the length — that is your circumference in mm and your EU size. The most common EU size for women is 52–54. If you are between sizes, we recommend sizing up for comfort. Free resizing is included within 60 days of purchase, so there is no risk in ordering and adjusting after delivery. Use our ring sizing guide for more detail.

All three metals complement the Asscher beautifully, but each creates a different mood. White gold is the classic choice — its cool tone emphasises the Asscher's geometric, architectural lines and the D–E colour of the stone. Yellow gold creates a warmer, more vintage feel that references the Art Deco era when Asscher cuts were at their most fashionable. Rose gold adds a romantic softness to the angular cut — a modern, feminine contrast. If you are unsure, book a free consultation and we can help you decide based on your skin tone and style.
