3ct Marquise Solitaire Diamond Ring 18kt

A three carat marquise diamond is a love story in motion. It feels feminine and full of light with its long silhouette catching every breath of sparkle. This beautiful shape has always symbolised love, romance and the kind of devotion that stretches effortlessly into the future.

Handcrafted in rich yellow gold, this ring is created with everyday wear in mind. The cathedral setting lifts the diamond gracefully, letting the light pour through while keeping the design refined and timeless. Beneath the centre stone sits a gallery rail that adds an extra layer of security so your ring feels safe and comfortable wherever life takes you.

The 2.5 millimetre solid gold band is made for real life. Strong, elegant and luxurious to the touch. It is designed to be worn, loved and lived in.

A piece that celebrates femininity, intention and forever moments.
