How a Diamond is Formed. In order for diamond to form there must be an available source of carbon and relatively narrow ranges of temperates and pressures must align. This happens around 100 miles below the crust. Once crystalized the diamonds must be rapidly transported to the surface without undergoing substantial change.
Quora User, studied at Geology. Diamonds would not melt in lava, they would burn. Diamond's ignition point in air is 850-1000 degrees Celcius. Depending on the type of lava, the temperature is 700 to1200 degrees Celcius potentially hot enough to ignite a diamond. The stability and strength of diamonds is greatly exaggerated in common knowledge.
