Jewellery School GuideGemmologist: the person everyone turns to when a stone is on the table.
The work — identification (natural, treated, synthetic), grading, valuation support, buying advice. Loupe first; then microscope, refractometer, spectroscope.
The ladder — the gemmology foundation then identification methods; online theory first via GT100e if that suits your schedule.
Where the jobs are — retail gem advisory (the entry lane), wholesale and trade houses, auction salerooms, labs — and inside every jewellery business, the one person who truly knows stones.
Free start, today — the gem webinar replays, Name That Gem and the Gem Globe. Serious within a week? The 2-minute finder maps the route.
