The shape of a laboratory grown diamond can completely change the personality of a jewellery piece. Some cuts feel familiar and versatile, while others give rings, earrings or pendants a more distinctive outline. Knowing the types of laboratory grown diamond cuts makes it easier to narrow down your options without getting lost in a long list of shapes. From round and princess to pear, marquise and baguette, each has a different visual character and works particularly well in certain jewellery designs. Cut Versus Shape: The Mix-Up Everyone Makes Before getting into the different types of laboratory grown diamond cuts, it helps to clear up one common confusion. Shape The silhouette What you notice when looking at the stone from above. It determines whether the stone appears round, oval, pear, emerald, cushion, or another form — mostly a matter of visual preference. Cut The light performance How the diamond is fashioned to work with light — proportions, symmetry, polish and facet arrangement. It determines the brightness and sparkle returned to the viewer. Understanding these two aspects makes it easier to explore the various laboratory grown diamond cut categories and identify the details that matter when choosing a jewellery piece. The Important Types of Cuts to Know The laboratory grown diamond cuts you see in jewellery generally refer to the shape and faceting of the stone. Here are the common cuts you'll come across — each links to its collection at beYon. Round Cut → Engineered to maximise brilliance — more sparkle per carat than almost any other shape. Suits nearly every hand and setting. Princess Cut → Clean, square edges with a modern silhouette. Often looks larger than a round of the same carat weight. Oval Cut → Elongates the finger with a shape that feels a little more distinctive — nearly as brilliant as a round. Pear Cut → Rounded end meets a pointed tip — a teardrop that elongates beautifully in earrings and pendants. Cushion Cut → Rounded corners and a soft, pillow-like outline — a warmer, slightly vintage feel. Emerald Cut → Long step-cut facets create a hall-of-mirrors effect — understated elegance over maximum shine. Marquise Cut → Pointed ends and an elongated, eye-shaped silhouette — visually stretches the finger more than most. Radiant Cut Combines the brilliance of a round with the crisp corners of an emerald — a versatile middle ground. Asscher Cut Essentially a square emerald — favours clarity and geometry over sparkle. A quietly bold choice. Once set, the cut becomes the personality of the whole piece. beYon's The Cut collection brings together a variety of distinctive shapes — including marquise, baguette and hexagon — making it easy to explore different types of laboratory grown diamond cuts across jewellery designs. How Light Interacts with Different Cuts The arrangement of facets can influence the way a laboratory grown diamond looks under different lighting conditions. A stone can appear lively in one setting and more reflective in another because light interacts with its facets in different ways. Brilliant-style cuts Triangular and kite-shaped facets designed to maximise light return. A round brilliant has 57–58 facets that create lively flashes of white light and colour. Step-cut designs Larger rectangular facets arranged in rows like steps — as in emerald and Asscher cuts. Fewer, wider flashes that emphasise clarity and geometry. beYon's collection also shows how different kinds of laboratory grown diamond cuts can create distinct visual effects — from the clean lines of a baguette to the soft curves of a marquise.

How to Choose the Right Cut for You With so many laboratory grown diamond cut categories to pick from, narrowing things down usually comes down to a few honest questions rather than following trends. ? Sparkle or architecture? Round, princess, and oval cuts lean toward brilliance, while emerald and Asscher cuts favour clarity over shine. ? Classic or contemporary? Cushion and round cuts suit a more traditional wardrobe, while marquise and pear cuts fit someone whose style already runs a little bolder. ? Ring, earrings or pendant? Pear and marquise shapes elongate beautifully in earrings and pendants, while round and princess cuts hold up well in everyday rings. ? Familiar or rare? Round and princess cuts are the most common, while radiant and Asscher cuts stand out precisely because fewer people choose them. FAQs Q1. What are the most popular types of laboratory grown diamond cuts right now? Round, oval, and cushion cuts remain the most requested shapes, largely because they suit a wide range of settings and personal styles. Round continues to lead simply because of how much brilliance it produces relative to its size. Q2. Does the cut affect how big a laboratory grown diamond looks? Yes. Elongated shapes like oval, pear, and marquise tend to look larger than round or cushion stones of the same carat weight. This is one of the easiest ways to get a bigger visual impact without increasing the budget. Q3. How is a lab-grown diamond cut grade different from a natural stone's grade? The grading criteria are identical, since both are assessed on proportion, symmetry, and polish using the same standards. The only difference is how the stone was formed, not how its cut quality is measured. Q4. Which laboratory grown diamond cut is easiest to maintain day to day? Round and cushion cuts tend to hide small scratches and everyday wear better than sharper-edged shapes like princess or emerald. Their rounded facets are also generally less prone to chipping at the corners.
