The property due to which an element exists in two or more forms that differ in their physical
and some of the chemical properties is known as allotropy. The crystalline allotropes of carbon are diamond, graphite and Buckminsterfullerene.
    
Diamond has a three-dimensional net work involving strong C–C bonds, which are very
difficult to break and, in turn has high melting point.

Allotropy or allotropism (from Greek  (allos), meaning "other", and (tropos), meaning "manner, form") is the property of some chemical elements to exist in two or more different forms, in the same physical state, known as allotropes of these elements.
allotropes of carbon are diamond,graphite,coal.........
diamond has high melting point because it has giant molecular structure.
