Lighting
Hiddenite is strongly pleochroic, meaning there is a color intensity variation when a crystal of it is viewed from different directions.

Clarity
Hiddenite is a transparent gem and should be eye clean at least.

Cut
Hiddenite usually gets a step (emerald) cut. Hiddenite is strongly pleochroic, meaning there is a color intensity variation when a crystal of it is viewed from different directions. The top and bottom of the crystal reveal the deepest colors and experienced cutters take advantage of its effects. Due to hiddenite's cleavage, splintery fracture and strong pleochroism, it is considered a real gem cutter's challenge.
