It does not have the highest thermal conductivity that honour go,s to diamond.

diamond is elemental carbon - admittedly a nice sparkly allotrope but it is just as much carbon as graphite.

To be honest I didn't realise it had a high thermal conductivity

Graphene is higher than diamond, which makes sense since it has uniquely high electrical conductivity.  According to Wikipedia, though, Helium-II (the superfluid state of Helium) is the highest.  Diamond is the one you're most likely to see being used in bulk, however.

That property can be used to tell diamonds from fakes ...

Thermal conductivity: Cubic zirconias are thermal insulators while diamonds are among the most efficient thermal conductors, exceeding silver's thermal conductivity. This makes telling the difference between diamond and cubic zirconia quite easy for those with the right instruments.

 i get the point .........but what makes the silver actually high conductivity from same atomic structure.....

Same atomic structure as what..?
