Anatomy of the cut

Fifty-seven planes, one job.

A brilliant cut is an optical instrument. Every laboratory-grown diamond we set is proportioned so that light entering the table leaves through it again, rather than escaping through the base.

  1. Table53%The flat top window. Its width sets how much light enters before the crown angles take over.
  2. Crown34.5°Eight bezel facets and eight stars. This angle decides how much of the returned light splits into colour.
  3. Girdle1.7%The scalloped waist where the stone is set. Faceted rather than polished, so it catches a thin ring of light.
  4. Pavilion40.75°The mirror. Light that clears this angle reflects twice and leaves through the table instead of the base.

The design studio

The conversation becomes the brief.

Describe a shape, feeling, reference, or constraint. The studio turns each decision into a visible specification and a labelled concept render.

Design conversation

An oval center. Fine yellow-gold bezel. Low enough for daily wear.

I kept the profile low and the band at a conservative starting width. Would you prefer a flat or softly rounded profile?

Concept to craft

AI proposes. CAD resolves.
