Join master gem cutter Justin K Prim for a live demonstration revealing the fascinating process of turning raw crystals into precision-cut gemstones. Watch as he explains each stage — from selecting rough material to faceting and polishing — while sharing insights into tools, techniques, and the craftsmanship behind fine lapidary work. Perfect for anyone curious about the art and science of gem cutting, this free session offers a rare glimpse into how beauty is brought to life from within the stone.

Join us for an immersive introduction to the art of lapidary - the ancient craft of cutting, shaping, and polishing gemstones. In this one-hour session, you’ll learn how to trim rough stone slabs to remove excess material, then refine and smooth your piece into a polished cabochon - a gemstone with a domed top and flat base, as traditionally used in historical jewellery. Guided by Cleo and Sarah, you’ll gain hands-on experience using professional lapidary tools and techniques. Together, you’ll explore the transformation from raw stone to finished gem, discovering the patience, precision, and mindfulness that define this timeless art form. As Sarah shares: “Cutting gemstones became one of the most therapeutic and satisfying activities I’ve ever experienced. Watching a rough stone transform into a thing of beauty - knowing that you had a hand in its creation - is deeply fulfilling.” Those who prefer to observe the process rather than participate are warmly welcome to watch the demonstration free of charge.
