Design & Craftsmanship

The focus of this design is the centre stone. The four-prong basket setting lifts the diamond just above the band, allowing light to enter from all angles while keeping the profile comfortable for everyday wear. The band is gently tapered towards the stone, drawing the eye to the centre and creating a refined, elegant silhouette.

Platinum 950 has a naturally bright, white tone that complements the colourless DEF diamond, enhancing its brilliance without the need for plating. The smooth inner surface of the band is shaped for comfortable wear throughout the day.

About the Lab-Grown Diamond

This ring features a laboratory-grown diamond, created using advanced technology that replicates the natural diamond-forming process. The result is a real diamond with the same physical, chemical and optical properties as a mined diamond, but produced in a controlled environment.

• Ethical choice: Lab-grown diamonds are produced without traditional mining.
• Brilliant appearance: Round brilliant cut for maximum sparkle and fire.
• Colourless grade: DEF colour sits at the top of the diamond colour scale.
• VS clarity: Very small inclusions, not visible to the naked eye in normal viewing.

Choosing a lab-grown diamond allows you to enjoy the look and feel of a classic diamond solitaire while aligning with modern values around transparency and responsible sourcing.
