When a diamond is hit by an X ray it becomes fluorescent allowing it to be distinguished and removed from the other material The final method of extraction used to separate diamonds from waste material is simply by the naked eye
First by methods that separate by specific gravity and then by more selective means such as grease tables and X ray extraction devices that most directly separate the diamonds Grease tables take advantage of the fact that diamond is essentially a water repellent substance and stays dry Other rock components of the kimberlite are wet by water
Canadian diamonds are diamonds which have been mined in any one of the major Provinces and territories of Canada Diamond rich areas weren t discovered in Canada until the early 1990s Before that time diamonds were only known by Indigenous communities citation needed For the first 60 years of the 20th century diamonds originated from kimberlite pipes and alluvial deposits in places such as
