Buying guide
An oval is a brilliant cut stretched into an elongated outline. It spreads its weight over a longer surface than a round of the same carat, so a 1.5 carat oval looks larger face-up and makes the finger appear longer. Ovals can show a darker bow-tie shape across the middle; a well-proportioned stone keeps it faint. As a 1.5 carat oval solitaire engagement ring, the shape needs nothing around it to stand out.
The 1.5 carat figure is the oval center alone. Pavé and hidden halo details add more lab-grown diamond beyond the center.
Platinum is naturally white and dense, with a heavy feel on the hand. White gold gives a similar cool look at a lower price, while yellow and rose gold warm up the outline of the oval. Gold rings come in 10K, 14K or 18K.
