Normally, it will burn rather than melt (at somewhere around 1560 degrees F). Diamonds meant to be kept (like rings) are coated with boric acid (keeps out the Oxygen); they still get to burn (but at a much higher temperature).
PS:
Brian found the melting temperature. Thanks.
So an uprotected diamond will burn (800 C) before reaching its melting temperature (1200 C). Since the question involves a fire (oxygen is present) then the answer is that you can't melt a diamond in a fire.
As for a diamond coated with boric acid, I still have not found the temperature at which it burns. However, I would suppose that as soon as it melts, it is no longer "coated" with boric acid and burns immediately.
House fires rarely reach above 600 C.

Diamond is very hard and can be only made under very high temperature and pressure. The melting point is 1200*C. It can be possible if you can melt the diamond in the lava in volcanic area.
