There are various kinds of gem polishers. Faceting machines are used to cut transparent gems, like diamonds. Cabochon machines are used to grind low rounded domes or irregular shapes, usually opaque; eg. much turquoise is cut in cabochon form. A tumbler is used to round and polish a wide variety of less valuable gems.
