The video shows the different steps of cutting and polishing a gemstone, faceting in particular. Im cutting a large piece of quartz in the portuguese design. I use a facetron machine . The various laps used are nickel bond diamond laps, 100, 260, 360, 600, and 1200 grit laps. The prepolish lap i used is a lightning lap 3000 grit lap. The polishing lap i used is a gearloose lapidary creamway lap. The stones finished weight was 192.5 carats and the total time cutting was 30 hrs. and 35 min.. There were 5 tiers of facets on both the pavillion and crown.
