The cut

Step cut

Top view
13.05 mm8.35
Side profile

Long, parallel facets step down from a large flat table to the edge, like a staircase. Light moves across the stone in broad, clean flashes rather than sparkle, so its colour and clarity are easy to see.

  • Broad, mirror-like flashes
  • Colour and clarity on show
  • Calm, architectural look
