The oval cut is an elongated brilliant: a diamond with the same fire and sparkle as a round, drawn out into a graceful oval outline. It reads larger than a round of the same weight, suits almost every hand, and works as a solitaire or within a halo. Below is what to look for, how to set it, and how we commission an oval ring for you.
What an oval cut looks like
An oval is cut with the same brilliant faceting pattern as a round, so it returns light in much the same way. The difference is the outline. A well-proportioned oval has a length-to-width ratio of roughly 1.35 to 1.50: lower than that and the stone looks almost round; higher and it reads as a slim ellipse. Within that range the choice is personal, and we source certified stones to your brief across it.
Every elongated brilliant carries a bowtie, a faint shadow across the centre where light is not fully returned. It is normal, not a fault. In a poorly cut oval it appears as a dark band; in a well-cut one it is soft and barely noticeable, and the stone stays bright end to end. We source certified stones to your brief and share full grading and detail so you can choose ovals where the bowtie is faint, because a photograph rarely tells the whole story.
Who an oval suits
The oval is one of the most flattering cuts on the hand. Its length draws the eye along the finger and lengthens it, which many find slimming and elegant. Because the shape spreads the diamond out rather than packing it into a compact circle, an oval faces up larger than a round of the same carat weight, so a given budget buys visible size. With no sharp corners to catch or chip, it wears well over years of daily use.
Settings and metals
An oval looks composed in a simple solitaire, where the elongated outline carries the design on its own. A halo of small diamonds adds noticeable size and sparkle, and is a popular way to make a modest carat weight read larger. Diamond-set shoulders, where small stones run partway down the band, add light without competing with the centre. However the stone is set, the two pointed ends are the vulnerable part, so we protect them with secure claws positioned at the points.
We make our settings in platinum and in 18ct gold, white, yellow or rose. Platinum is dense, naturally white and highly durable; 18ct gold offers the same strength with a choice of colour. Every setting is hallmarked at the London Assay Office, which is included.
Carat and proportion
Because an oval spreads its weight across a longer outline, it presents more diamond to the eye than a round of equal carat, so the size you see matters as much as the figure on the certificate. Two ovals of identical weight can look quite different depending on their length-to-width ratio. We guide you by appearance first and weight second, and pair the proportion you choose with a setting scaled to suit it. Every centre stone comes with GIA or IGI certification.
Commissioning your oval with us
Hatton Garden Bespoke Jewellery draws on a family in the trade since the late 1960s across three generations, with our founder in Hatton Garden since 1999. We design in-house using CAD and hand-finish each piece on our own workshop bench, with casting and setting carried out by trusted specialist workshops. After a free, no-obligation consultation we provide a fixed written quote, then move to CAD, and from your approval the ring is ready in three to four weeks. Settings start from £800 and complete bespoke engagement rings from £1,500, with most commissions between £3,000 and £12,000.
Is an oval cut good value?
Yes. Because it faces up larger than a round of the same weight, an oval gives more apparent size for your budget, and it typically costs a little less per carat than a round. You see more diamond for the money.
Does an oval sparkle like a round?
It uses the same brilliant faceting, so it returns light in much the same way and sparkles brightly. The main difference is the bowtie across the centre, which on a well-cut stone is faint and leaves the diamond lively end to end.
Natural or lab-grown?
We offer both. Natural and lab-grown ovals are chemically and optically the same diamond; a lab-grown stone of comparable quality costs less, which often buys more size. We source both to your brief and share full grading so you can decide on appearance and budget.
To begin, you can start with a diamond or start with a setting, and we will build the ring around your choice. Book a free, no-obligation consultation through our contact page; we reply within four working hours, Monday to Friday. You may also prefer the round brilliant cut or the cushion cut.
