No, there is no evidence to suggest that the moon Callisto has diamonds on its surface. Callisto is primarily composed of water ice and rock, and there is no known geological process that would lead to the formation of diamonds on this moon.
From brightest to dimmest, the order of brightness for the four largest moons of Jupiter when viewed from its surface is Io, Europa, Ganymede, and Callisto. Io tends to be the brightest due to its active volcanism, while Callisto is the dimmest because of its icy composition and lack of surface activity.
Jupiter's moon Callisto has the temperature 134 k (kelvin) or -139 c (Celsius)
The surface of Callisto is heavily cratered and extremely old. It does not show any sign of volcanic activity.
