Lab-Grown Diamond

The diamond in this ring is lab-grown, created using advanced technology that replicates the natural diamond-forming process. It has the same physical, chemical and optical properties as a mined diamond, with a more modern and considered approach to sourcing.

• Real diamond: Not a simulant – a true diamond, grown in a lab.
• Brilliance: Cut to maximise fire and sparkle, especially in the heart shape.
• Value: Allows for a larger carat weight without the mined diamond price tag.

14K White Gold Setting

The ring is crafted in 14K white gold, chosen for its balance of durability, brightness and comfort for everyday wear. The cool white tone pairs perfectly with the crisp sparkle of the lab diamond and complements both warm and cool skin tones.

The band is designed to sit comfortably alongside a wedding band, making it easy to stack and style after the proposal.

Hidden Heart Detail

One of the most special features of this design is the heart-shaped under-gallery beneath the centre stone. From above, you see a classic heart-shaped diamond. From the side and back, a second heart is revealed in the metalwork – a small, private detail that only you (and the person you choose to show) will know is there.

It is a subtle “I love you” touch that turns this ring from a beautiful solitaire into something a little more personal and meaningful.

Ring Size

This design can be made in a wide range of UK sizes. Please choose your usual ring size from the options above. If you are unsure, we recommend having your finger measured by a local jeweller before ordering.

For Your “I Love You” Moment

Heart-shaped stones are unapologetically romantic. This ring is for the proposals where you want the message to be crystal clear: I love you, I choose you, and I am not afraid to show it.

Whether you are planning a surprise proposal or choosing your ring together, this 3.01ct heart lab diamond solitaire offers a modern, meaningful way to say yes – with all the sparkle, and none of the compromise.
