Working at a gemstone appraisal lab, you must compare the “fire” (dispersion) and brilliance of a natural gemstone against a replica (or a version with a different cut). Your task is to examine photos taken from various lighting angles and identify facets where reflections and dispersion patterns are inconsistent—factors critical to determining the gem’s value and authenticity.
Gameplay & Skill Kits: “Optical Spot-the-Difference”—focusing on highlights and points of dispersion. Skill kits include “Point Light Source Tracking” (moving a virtual light source across the image to verify reflection paths) and “Fire Count” (automatically tallying dispersion points that exceed a specific brightness threshold). Level Overview: Levels 1–3400 feature the “Brilliant Cut (Round),” with variations in crown and pavilion angles; levels 3400–5100 feature the “Emerald Cut (Square),” with variations in the parallelism of step facets; levels 5100–6200 feature “Fancy Cuts (Heart, Pear),” where logical errors most frequently occur at the junctions of curves and facets.
