Oval Lab-Grown Diamond Engagement Rings in 18K Yellow Gold Under £4,000

The combination of an oval cut with a lab-grown diamond is one of the fastest-growing trends in engagement rings. The oval's 10% larger face-up area combined with lab-grown value means you can achieve a truly impressive ring at a fraction of the traditional cost.

The oval cut combines the brilliance of a round with an elongated silhouette that faces up approximately 10% larger than a round of the same carat weight. Its shape creates the illusion of longer, more slender fingers, making it one of the most flattering diamond shapes available. The oval has surged in popularity, becoming the second most requested shape for engagement rings.
