How Are Quartz Crystals Cut and Polished Our Pastimes.Sep 15, 2017 Once the gem cutter creates a rough shape by grinding, he uses a finer-grained wheel to sand the quartz. Sanding removes the scrapes left by grinding, smoothing the crystal. Sometimes, gem cutters use a process called lapping, which uses a spinning or agitating disk instead of a rotating wheel.
