Learn during 1 day the concave faceting techniques on a Ultra-Tec machine. This is an advanced class and reserved for faceters or students who have followed the faceting class before hand. Please prepare a few stones on Ultra-Tec dops and facet the pavilion, in order to profit a maximum during the concave class. You have the possibility to prepare the stones before the class in our workshop. Book one or two days of benchtime for that. A professionally equipped workshop is at your disposal with Ultra-Tec fantasy machines and faceting machines. The class price is CHF 300.-. The space is limited to 3 students.

The participant will know the correct handling of tools and be familiar with the security measures.
