Description

  • A composed expression from the Mappin & Webb Lab Grown Diamond Collection, defined by scale and balance.
  • Lab grown diamonds selected for consistent grading and independently verified quality.
  • A solitaire engagement ring designed to place full emphasis on form, symmetry, and light.
  • Created to reflect modern diamond innovation within a long-established jewellery tradition.
  • An assured design that aligns contemporary values with enduring design principles.

Enduring Perspective

Mappin & Webb’s jewellery heritage is shaped by generations of measured design and technical expertise. The brand’s approach has remained focused on proportion, material integrity, and longevity rather than transient style.

The Lab Grown Diamond Collection extends this perspective, introducing modern diamond creation while remaining closely aligned with the brand’s established standards and visual language.

Defined Presence

This solitaire engagement ring is centred on a round brilliant cut lab grown diamond, selected for its symmetry and controlled light performance. The design is intentionally restrained, allowing the scale of the stone to define the overall character.

Crafted in platinum, the ring features a 4.00 carat diamond graded D for colour and VVS for clarity. An accompanying IGI certificate provides independent confirmation of the diamond’s grading and quality.
