It all really depends on the cooling rate of the white dwarf, which is well known for various sizes of dwarf and composition. Your average white dwarf will cool down to the right temperature (8000-10000K) for the interior to change phase and start to crystallise out in a few billion years (around 2 billion is the accepted time). Most globs whose stars have white dwarf ages of around 2 billion years will start to have these remnants begin to crystallise out. The globs orbiting our galaxy are more than old enough to have some of their white dwarfs developing diamond cores.
