Retail jewellery is a knowledge profession wearing a sales jacket — commission follows credibility.
What the counter demands — identification basics (natural vs treated vs synthetic), the 4Cs and their trade-offs, metal purity maths, care guidance customers trust.
The education that feeds it — the gemmology foundation as spine; contemporary trends for the fashion floor; merchandising for the operations track.
The evidence — the school's own feedback includes buyers whose new skills "help in choosing purchases" and trade staff working in fancy-cut diamonds; read them in the published reviews.
Entry without quitting the job — the online GT100e starts the gem knowledge evenings-and-weekends.
What students say
“The skills learnt help me in choosing my purchases. I may consider helping a relative in the jewellery business and get included in the exhibitions.”
— Joyce T. (Singapore) · published student feedback
“I love all subjects, especially metalsmithing. I just love to fire and shape things.”
— Angie K. (Singapore) · published student feedback
