Saturated yellow, from nitrogen present when the crystal formed. Where a light yellow stone hints, these commit- the color carries across a room and holds under any light. Cut matters more here than in a colorless diamond, because proportions either concentrate the color or wash it out.

Long parallel facets cut in tiers, running to a straight-edged outline. No crushed ice, no scintillation- step cuts trade glitter for depth, returning light in wide planes that draw the eye down into the stone. With so few facets and such open planes, there is nowhere for a poorly made stone to hide.
