Optical Properties
Dichroscope results, polariscope interpretation, refractometer simulator, and pleochroism reasoner.
Lab Equipment
Chelsea filter simulator, spectroscope line calculator, and heavy liquid SG reference.
Gem Identification
Identify gems by optical and physical properties, hardness reference, and fracture/cleavage guide.
Advanced Analysis
Treatment detection checklist and proportion analyzer (origin guidance lives in the Learn section).
