Oval Cut Lab Grown Diamond Engagement Rings

Characterised by its elongated silhouette and graceful brilliance, the oval cut is a refined and romantic shape. With the sparkle of a round brilliant cut and a more elongated, artistic form, this cut is highly sought after for a reason. Modern, yet timeless, the unique look of an oval cut diamond makes it incredibly versatile and is the ideal choice for solitaires, halos and vintage-inspired styles. The elongated oval shape and sophisticated curves flatter the hand with a slimming effect on the finger and bring a level of femininity and classic romantic appeal to any engagement ring.
