Since its founding in 1994, Alexandre School of Optical Diamond Setting has stood at the forefront of advanced diamond-setting techniques. Situated in Antwerp, at the heart of the world's diamond trade, the school has earned a strong reputation, with a long list of graduates across the globe. Students can enroll in intensive 3-month courses covering all types of diamond setting, or join 5-day workshops designed around individual projects. The shorter sessions offer flexibility: students bring their own questions or focus on specific techniques, guided directly by the master.

With over 30 years of professional experience, Alexander Sidorov is internationally recognized for his pioneering work in diamond setting and microscopical engraving. He developed a highly specialized setting technique in which the microscope is used as the main working tool, combining engraving and stone placement. Alexander offers this know-how at his Optical Stone Setting School and works directly with students, providing guidance that enables high-quality results in both short and extended programs.
