Choosing an Oval Gemstone Engagement Ring

An oval gemstone creates a gentle, elongated line of colour along the finger. Its rounded ends give a softer impression than a marquise, while the extra length can make the centre seem more prominent than a comparably wide round stone.

Find the oval outline you prefer

Some ovals are full and softly rounded; others are much slimmer. Look at the length and width together and compare the colour under more than one type of light. Our blue sapphire engagement rings and lab grown emerald engagement rings show two distinctive colour options. Bear in mind that different gemstone species also have different care requirements.

Compare metal colours with the gemstone

An oval lab grown gemstone can look strikingly different in yellow gold, rose gold and platinum. Cooler metal colours may give blue or green centres a crisp frame, while warmer alloys can add softness to pink or golden tones. Look at the actual stone against the metal wherever possible rather than relying on edited photographs. If the oval is especially elongated, check the spacing and support at both ends of the setting.

A gemstone solitaire engagement ring leaves the colour uninterrupted, while a diamond halo frames it with white sparkle. Check how the claws follow the curves and whether the basket will sit comfortably beside a wedding band. For a squarer, softer outline, explore our cushion cut gemstone rings.
