3ct Cushion Cut Square Diamond Trilogy Engagement Ring with Half Moon Side Stones, 4.50ct Total

A proper statement piece. This trilogy ring features a 3ct cushion cut diamond at the centre, with two perfectly matched half moon diamonds sitting either side. The shape of the side stones wraps in beautifully, giving the ring a wider look on the finger and a really seamless finish.

It’s one of those designs that instantly stands out. You get the softness of a cushion cut, paired with the structure of the half moons, which creates a bold but still very elegant look.

💎 Key Features

Centre Stone
A 3ct cushion cut diamond, hand picked by the Layla Diamonds team to ensure a bright, well balanced stone with a beautiful shape. Each diamond is selected for its clean finish, with excellent polish and symmetry and no fluorescence, so it looks crisp and lively in all lighting.

Side Stones
Two half moon diamonds, carefully matched to sit perfectly against the centre stone. They add width and flow to the design, giving that full finger coverage look without feeling bulky.

Design
A classic trilogy setting with a modern edge. The combination of the cushion centre and half moon sides creates a smooth, continuous spread of diamonds across the finger, making the ring feel larger and more impactful.

Total Carat Weight
