Prior to modern day discoveries in Brazil and South Africa, the only known source of diamonds was [[India]]. In [[ancient]] times diamonds were called ''adamant'', meaning "indestructable". Most diamonds are irregular in shape and rather unappealing to the eye. The color ranges from dull yellow to dirty brown.
  
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.
