This master class combines geology, craftsmanship, and a live feeling of touching Ural stone. Participants will get acquainted with selenite and serpentine, learn how to process them, try their hand at the machine, and create their own souvenir - an item that merges natural beauty, handwork, and local tradition. It is hard to imagine the Urals without discussions about stone, craftsmanship, and a special respect for the material in which nature has already created a pattern, color, and character. This master class offers the opportunity to feel this theme not through a museum showcase, but through one's own hands. It is dedicated to Ural decorative stones and is structured so that participants not only hear about selenite and serpentine but also understand how they differ, how they behave in work, and why the craft of stone cutting in the Urals has become an important part of local culture. The main value of the event lies in the combination of educational and practical parts. Participants will learn about the hardness of the stone, the peculiarities of its processing, traditional techniques and tools, and then move on to real action. Under the guidance of mentors, they will get acquainted with the basics of working on the machine and try their hand as stone cutters. This format is especially engaging for teenagers: it offers both concrete knowledge and a sense of real craftsmanship experience, where the result depends on accuracy, attention, and patience. This is not an abstract story about minerals, but a meeting with a material that requires respect and precision. Where to go in Yekaterinburg, knows KudaGo.
