The cut

Fine step cut

Top view
20.29 mm10.29
Side profile

A step cut with more, narrower rows of facets. The extra steps give the long, clean flashes of a step cut with a livelier, more layered glow, and they hold colour evenly across the stone.

  • More rows of narrower steps
  • Richer, layered flashes
  • Even colour from edge to edge

Sphene has more fire than diamond. In a stone this size the dispersion is spectacular: every movement throws red, orange and green across a lime green body. Large clean sphene is rare, and a heart this size rarer still.

Loupe clean, with no heat and no treatment.
