This final stage of the jewellery creation process is just as important as previous stages. Several rounds of polishing are applied to each George Pragnell creation to ensure that both the precious metal holding the gemstones, and the gemstones themselves, complement each other. In the first stage, a brush, sized according to the intricacy of a piece, is used to remove marks left by the goldsmith. The next procedure involves polishing with thread. It is an extremely time consuming process, but necessary to provide adequate polishing to the inside of the setting. The entire polishing process can take hours per piece and must be done both before and after the gemstones are set.
