@thejourneyofagem: Day 2/75 becoming an Accredited Gemologisy 💎 Todya was all about light refraction in a gem (dont quote me im no expert, please do correct me if im wrong though). Based on various factors the light enters a gem and either singly or doubly refracts. Using a refractometer we can measure these light refractions in order to properly identify the species of gem. #gemmology #accreditedgemologist #AIGS #bangkokexpat #preciousstones #workwearstyle
