Oval cut lab grown diamond engagement rings became the most requested shape globally in 2025, overtaking the round brilliant for the first time in modern jewelry history. The reason is value. An oval of the same carat weight as a round stone shows more face-up surface area, so it reads larger on the finger while costing the same.
Every oval cut lab grown diamond engagement ring in this collection is made to order in our Surat studio. The centre stones are Real CVD Lab-Grown Diamonds in VVS-VS clarity and the D-E-F Colorless range, grown using Chemical Vapor Deposition technology. Because the oval's elongated table leaves more of the stone visible, that clarity grade does more visible work here than it does in a smaller, busier cut.
The oval also flatters the hand. Its long axis draws the eye down the finger rather than across it, which is why it photographs so well in the hand-forward angles people actually share. Available in solitaire, halo, three stone, pave, eternity and mixed-shape settings, in 9K, 14K and 18K solid gold across white, yellow and rose, plus platinum.
2 Carat Oval Lab Grown Diamond Engagement Rings
Two carats is the most searched weight for an oval cut lab grown diamond engagement ring, and it is where the shape's advantage shows most clearly. A 2 carat oval measures roughly 9mm by 7mm against a 2 carat round at about 8.1mm across, so the oval covers noticeably more of the finger for the same weight and the same price.
At Ronora a 2 carat oval sits in the middle of the range rather than the top of it, which means the budget that buys a 2 carat mined stone elsewhere reaches considerably further here. Every gold piece comes with an SGL jewelry certificate and every platinum piece with an ITPL certificate. Every lab grown diamond of 1 carat or more also comes with its own IGI report.

Frequently Asked Questions
How much does an oval lab grown diamond cost?
Each ring is made to order, and the price depends on carat weight, metal and setting. Every product page shows the price of each option.
Is a lab grown diamond suitable for an engagement ring?
Yes. A lab grown diamond is chemically, physically and optically identical to a mined diamond. It measures 10 on the Mohs hardness scale exactly as a mined stone does, so it handles daily wear the same way. The only difference is origin and price.
What is the difference between a lab grown diamond and moissanite?
A lab grown diamond is a real diamond, identical in every physical and optical property to a mined one. Moissanite is a separate gemstone. It is slightly softer at 9.25 on the Mohs scale, throws more coloured fire, and costs considerably less. We label every ring clearly so you always know which stone you are buying.
Why does an oval look bigger than a round diamond of the same weight?
Carat is weight, not size. The oval distributes that weight across a longer, shallower footprint, so more of the stone faces upward. A 2 carat oval measures roughly 9mm by 7mm while a 2 carat round measures about 8.1mm across.
What clarity and colour are Ronora's oval diamonds?
Every oval lab grown diamond we set is VVS-VS clarity (VVS1 or VVS2 wherever available, VS1 only when neither is) in the D-E-F Colorless range. We do not stock lower clarity or colour grades, so there is no upgrade tier to negotiate.
Are these ovals IGI certified?
Every lab grown diamond of 1 carat or more is IGI certified, and the certificate ships with the ring. Smaller accent and pave stones are not individually certified, which is standard practice across the industry.
