We are Victoria Raynaud and Justin K Prim, two professional gemcutters, gemologists, authors, and teachers based in Lyon, France.

Every gemstone is selected and cut by us, with the care and precision that come from years spent working at the bench. Alongside our one-of-a-kind gems, you’ll also find the books, tools, and educational resources we use, create, and teach with.

Our workshop is proudly certified Fabriqué à Lyon, a label that reflects the importance we place on local craftsmanship and quality.

Every gemstone from Magus Gems comes with its own Certificate of Authenticity, created to highlight the craftsmanship behind each stone.

It records the gemstone’s variety, weight, dimensions, cutting style, known treatments and, whenever possible, its provenance. It also includes the name of the gemcutter who cut it.

Each certificate is a lasting record of the care, precision, and individual work that went into your gemstone.

This certificate is not a gemological laboratory report, but one can be arranged upon request.
