3ct Oval Lab Grown Diamond Engagement Ring in 18ct Yellow Gold
3ct Oval Lab Grown Diamond Engagement Ring in 18ct Yellow Gold
🚚 Next-day UK delivery available on all in-stock items.
A modern interpretation of the traditional solitaire, this 3ct oval lab grown diamond engagement ring in 18ct yellow gold is designed for those drawn to contemporary proportion and enduring meaning.
Set horizontally in a refined east-west orientation, the elongated oval diamond creates a distinctive silhouette across the finger — offering a more architectural alternative to the classic vertical oval engagement ring. The result is a balanced and considered design that feels both current and deeply personal.
The 3 carat oval lab grown diamond is secured in a minimal four talon claw setting, allowing light to enter from all angles while maintaining a sculptural form. This contemporary east-west setting subtly maximises finger coverage, giving the presence of a larger stone while preserving a clean and understated aesthetic.
Chosen to mark a moment that deserves to be remembered — an engagement, a promise, a decision about the future — this oval lab grown diamond engagement ring is crafted not only for brilliance, but for significance. It is a piece intended to honour a commitment and be worn as a lasting reminder of the life you are choosing together.
Each ring features a 3ct oval cut lab grown diamond set in solid 18ct yellow gold. Lab grown diamonds share the same physical, chemical and optical properties as mined diamonds, offering exceptional clarity and fire in a more conscious and traceable form.
This engagement ring design is by contemporary jeweller Christine Sadler and you can view it in person at our studio in Ayr, Scotland or order it online with a 30 day return.
