Lavoisier showed that by concentrating the Sun's rays (through a magnifying glass), on a diamond in an oxygen atmosphere, that diamond could be burnt, and gave off the same quantity of CO2 as would a piece of carbon. The temperature for this combustion starts around 700 oC.
In an inert gas, diamond will revert to graphite at about 1700 oC.
