Isabella is an oval lab-grown diamond engagement ring in 18k yellow gold with a four-prong tapered solitaire setting. The elongated centre stone gives the ring a graceful profile, while the plain band keeps the focus firmly on the oval diamond.

The 2.10mm band gives this yellow gold lab-grown diamond ring a balanced foundation. Yellow gold introduces warmth beneath the centre stone, while the tapered mount creates a clean transition into the setting without the addition of a halo or diamond-set shoulders.

Available across a choice of centre-stone carat weights and colour grades, Isabella is a refined yellow gold oval lab-grown diamond solitaire engagement ring. Its wedding-ring-friendly setting is designed to fit alongside most standard wedding rings.

    Isabella Oval Lab-Grown Diamond Solitaire Engagement Ring in 18ct Yellow Gold

    Isabella places an elongated oval lab-grown diamond at the centre of a classic 18ct yellow gold solitaire. The clean band and tapered shoulders draw attention to the diamond's shape, while the warm metal gives this understated design its character. With no halo or extra shoulder stones, the oval remains the clear focal point.

    Four-Prong Tapered Setting and 2.10mm Yellow Gold Band

    Four prongs hold the oval centre stone in an open setting. The 2.10mm band provides a balanced profile, and its tapered shoulders create a smooth transition towards the diamond. Isabella is designed to sit alongside most standard wedding rings, making the side profile and future band pairing worth considering when choosing your size.

    Choosing a Certified Oval Lab-Grown Diamond for Isabella

    Choose the carat weight and colour grade that suit your preferred proportions, rather than relying on carat weight alone. The product specification lists VS1 clarity and independent GIA or IGI grading for the centre diamond. Lab-grown diamonds have the same essential physical and chemical properties as natural diamonds; their origin is what differs.
