This is because diamonds as well as being the most brilliant and precious of stones are also one of the hardest materials known to man. Their earliest use in industry was as an abrasive powder for sawing and polishing operations and for grinding metal cutting tools. Many kinds of drills use diamonds as cutters. The introduction of the carbonado or black diamonds of Brazil less brittle than other forms greatly improved rock drilling for geological and mine prospecting. But they have become so scarce that other suitable varieties have had to be substituted. Diamonds are also employed for cutting glass and porcelain for fine engraving for dental surgery and for bearings in watches.
