Lab-Grown Oval Cut Diamonds: The Complete Guide
An oval lab-grown diamond is a brilliant-cut, elongated stone with softly rounded ends and classic sparkle. Its length-to-width ratio typically sits between 1.30 and 1.50, lengthening the finger and flattering the hand. With no sharp points, it is less prone to snagging than pointed shapes. It suits anyone wanting a refined, size-enhancing alternative to a round.
Overview
The Oval diamond offers a sophisticated twist on the classic round, characterised by its elongated, graceful form. It exudes a sense of refined elegance while maintaining impressive brilliance. Its extended shape not only makes the stone appear larger but also adds a unique dimension to its overall appearance. This cut is especially favoured for its ability to elongate the look of the finger and complement a variety of jewellery settings, making it a versatile option for both modern and traditional designs.
Origin and development
The oval cut evolved as a creative adaptation of the traditional round, emerging from the desire to offer something both classic and distinct. Historically, cutters sought to create a diamond shape that maintained the brilliance of the round while providing a unique, elongated form. Over time, the oval has become a popular choice for its ability to blend the best qualities of classic and modern aesthetics. Its development reflects both artistic vision and technical advancements in diamond cutting, securing its place as a contemporary favourite.
How the oval cut is shaped
The oval cut is defined by its smooth, elongated outline with gently curved edges that taper gracefully at the ends. Its faceting pattern is similar to that of the round brilliant, ensuring consistent sparkle throughout the stone. The shape is designed to accentuate the stone’s length, giving it a sleek and modern appearance. This elegant geometry flatters the hand and adds a dynamic flow to any piece of jewellery, making it an ideal choice for those who appreciate both tradition and innovation in design.
Why choose a oval cut
Oval diamonds stand out for their enhanced light performance and distinctive silhouette. The elongated shape increases the surface area, often resulting in a greater visual impact than a round of the same carat weight. Their well-proportioned facets provide a continuous and fluid sparkle that is both elegant and captivating. This cut also offers a softer alternative to the round, providing a unique balance between classic brilliance and contemporary style, while being particularly effective in creating an illusion of greater size.
What to look for when buying
In elongated brilliant cuts, check the length-to-width ratio for the silhouette you want, and ask us to screen the bowtie, the shadow across the centre, which we inspect on every stone we shortlist. Every CRTD stone is independently certified by IGI or GIA at a VS1 minimum clarity.
Price
Lab-grown oval cut diamonds at CRTD start at $990 AUD for a one carat stone, with AU-inclusive pricing, the number you see is the number you pay. Larger carats and higher clarity grades are priced transparently across the range.
Choosing well
The detail that separates a fine oval from an ordinary one is the bowtie: a dark shadow that runs across the centre when faceting is uneven. A well-cut oval keeps it faint and shows even, symmetrical shoulders. Always view the stone face-up under good light, since a certificate alone will not reveal a pronounced bowtie.

Common questions
What is the ideal length-to-width ratio for an oval diamond?
For a balanced, finger-lengthening oval, a length-to-width ratio between 1.30 and 1.50 is a good starting point. Within that range the outline reads as a true oval rather than too round or too narrow. Ratio is a matter of taste, so view a stone face-up against your own hand before deciding, since the same numbers can look different in person.
Can an oval cut hide inclusions?
The oval is a brilliant cut, and its facet pattern scatters light across the stone, which helps disguise small inclusions. Even so, every CRTD oval is independently certified by IGI or GIA at a VS1 minimum clarity, so inclusions are already faint. At this grade the main thing to screen for is the bowtie shadow and even shoulders, not clarity.
Is an oval diamond durable enough for everyday wear?
Yes. The oval has no sharp points or corners, the areas most prone to chipping on pointed shapes, so it is a sound choice for daily wear. Its rounded, snag-free outline sits comfortably against the finger and catches less on fabric. As with any diamond, a secure setting and occasional professional checks keep it protected over time.
