Jewel grade diamonds are extremely rare and the technology for cutting and polishing them did not exist until the early Renaissance. As a result, diamond jewelry was more or less non-existant in [[Europe]] during the [[Middle Ages]]. Polishing with diamond dust and grindstones began in Burgundy c.1400 and by the mid 15th Century the diamond cutting trade had been established in Belgium. Early diamond cutting was fairly simple. The ''Mazarin'' cut did not appear until 1650. The ''Peruzzi'' cut, invented c.1700, eventually developed into the ''brilliant'' cut of modern times.
