I thought Diamond had the highest thermal conductivity but when I checked some sites on the internet I found references to parallel graphite with almost double the diamond value of 895 W/m*K.
And then there is the esoteric Helium II at less than 2.2 degrees K (that's really cold!) which may have a thermal conductivity of over 100 000!

Diamond - crystallized carbon - is the best conductor of heat at room temperatures.

And to complicate things, some diamonds conduct heat better than others.

The next best conductor of heat is silver, then copper.

The best conductor known today is liquid helium II, with a thermal conductivity greater tham 105 W/m.K (at temperatures near absolute zero).
