Available in platinum or 18k yellow gold, this oval solitaire engagement ring is ideal for those looking for a large oval lab grown diamond ring with a timeless yet contemporary appearance.

Why choose an oval solitaire engagement ring?

Oval solitaire engagement rings are known for their elegant elongated shape, which creates the illusion of longer, slimmer fingers while offering exceptional surface sparkle and finger coverage. The solitaire setting keeps the focus entirely on the centre diamond, making it one of the most timeless and popular engagement ring styles.

The cathedral setting gently lifts the centre diamond above the band using sweeping shoulders, adding additional presence, refinement and light exposure to maximise sparkle from every angle.

Lab grown diamonds also allow for larger carat weights and ultra high specifications, including D or E colour and VVS or VS1 clarity, while offering exceptional value compared to mined diamonds.

Unlike mass-produced engagement rings, every London Diamonds oval diamond is carefully chosen by hand for its brilliance, balance, proportions and fire. We prioritise how a diamond performs visually in real-world lighting conditions, not just the certificate grading alone.

Every London Diamonds engagement ring is handcrafted to order and normally ready for collection or complimentary fully insured shipping within approximately 3 weeks.
