A polariscope and dichroscope let a Jewellery Appraiser determine a gemstone's optical properties — single versus double refraction, pleochroism — to distinguish natural stones from glass, synthetics, or doublets. It's standard bench equipment taught in GIA and Indian Institute of Gemmology & Jewellery diploma programs, used alongside refractometers and loupes during grading. It's a supporting rather than headline skill in the appraiser's toolkit, so its salary contribution is moderate on its own even though accurate grading underpins the appraiser's credibility.
