Stone Type

At 1.5 carats, the diamond’s quality really comes into focus. A well-cut stone will feel brighter and more alive, while clarity helps keep the look clean and refined. It’s about choosing a diamond that looks beautiful from every angle, not just by size.

Shape

At 1.5 carats, the shape really starts to stand out on the hand. Round feels timeless and balanced, oval and emerald look more modern and elongated, while cushion and pear add a softer, more distinctive feel.

Popular Carat Sizes

A 1 carat diamond is a classic choice, with a balanced look on the hand. Smaller sizes like 0.75ct feel more subtle, while 1.25ct offers a little more presence. Differences are often subtle once set, so it comes down to personal preference.

Engagement Ring Trends

Engagement Ring Trends

1.5 carat diamond engagement rings are becoming a popular middle ground between classic and statement. They feel substantial on the hand without losing that sense of everyday wearability, which is why they’ve become such a go-to choice. Elongated shapes like oval and emerald continue to lead the way, creating a more elegant, lengthening effect on the finger. At the same time, simple solitaire settings remain a favourite, keeping the focus entirely on the diamond itself. Our master artisans create 1.5 carat rings that feel considered and easy to wear, with each design shaped around the stone rather than overworked. With our expert guidance, your ring becomes something personal, simple, refined, and made to be worn every day.
