Gemstones: From Sourcing to Selling
08 Jul 2026

Gemmology Rocks' new online course launches this September, teaching designers, retailers and collectors those street-smart industry skills.
Stop guessing, start buying with confidence, and selling with integrity.
Nobody sets out to be the jewellery designer who paid natural ruby prices for a glass filled horror. Or found out the emerald they just remortgaged their house to buy is synthetic. It happens to beginners and seasoned professionals alike, but most of the time it's avoidable.
Gemstones: From Sourcing to Selling is a six-week online course for jewellery makers, designers, retail professionals and collectors who are done crossing their fingers every time they buy a stone, or take on a gemstone project. You'll learn how to talk to a dealer, explore which gemstones are best suited to different jewellery designs, describe a stone correctly, and walk away from a deal with your wallet and your reputation intact, taught with the same fun, hands-on approach Gemmology Rocks is known for.
Every student gets a hand-picked collection of 18 gemstones to keep, sent out before the course even starts. While everyone else is squinting at stock photos, you'll be holding actual stones during live weekly sessions, learning to tell the good from the bad from the "absolutely not."
Across six one-hour Monday morning sessions, students cover cut and carat, colour and clarity, design and durability, pricing, and how to actually do business with dealers and customers. By the end, you'll know what you're buying, what it's worth, and how to sell it properly.
"Kerry is a fantastic and enthusiastic teacher and always there to help us, welcoming, fun, but with all the knowledge packed into it." (past student)
The course runs Mondays, 10:00-11:00am, from 7th September through 12th October.
