🎮 The Gem Game
Identify gems against the clock, with the same instruments you would meet in class — loupe, refractometer, spectroscope. The game the quizzes were built from.

🔍 Gem Reference & Identification
A free reference library of gem materials with measured properties — refractive index, specific gravity, spectra — the same data our students use, with cited sources. Look a stone up by name or property.

Where in the world each gem comes from, on a globe you can spin: mining localities for hundreds of materials, from Brazilian tourmalines to Burmese rubies.
Spin the globe →✨ BijouVision AI design
✨ BijouVision
JDMIS\u2019s own AI jewellery design tool: sketch an idea and watch it become design variations, renders and marketing visuals. Built around bench-ready output.
Try BijouVision →🤖 Ask the gem AI
🤖 AI Gem Consult
Ask a gemmology question in plain English and get an answer grounded in the same reference library — with the sources it used.
Ask a question →Which course-personality are you?
The oldest quiz in the family: the JDMIS course-personality quiz maps your interests and working style to the jewellery path that fits you — design, metal arts, gems or business.
Why we build these
Every one of these tools started life as classroom material at JDMIS, the Jewellery Design and Management International School in Singapore. The quizzes use the same photographs and instruments our gemmology students meet in GT100 and GT200 Gem Identification Methods; the reference library is the same one behind our courses. Play first — study later if you catch the bug.
