Yes it is possible. However it is impossible to do at standard temperatures and pressures like that at SATP. It has been done by the Z-Machine at the Sandia National Laboratories by using a pressure of 10 million times normal Atmospheric pressure. To create the pressure, the machine's magnetic fields hurled small plates at the diamond at 34 kilometers per second (21 miles per second), or faster than the Earth orbits the Sun.

Unfortunately in open air, the fact that is it large network of covalently bonded carbons make it extremely hard to melt in the first place. Secondly, diamond at high temperatures will not melt, rather it will prefer to burn, as characteristic of all carbon allotropes. A diamond will burn or oxidize when exposed to a hot flame in the presence of oxygen, for example an oxygen torch with a temperature of 800 degrees C (1,472 degrees F), according to The Merck Index, a standard chemistry reference work.


but it can be melted in the absence of air (or in vacuum) at a very very very high temperature
Since the melting point of diamond, the highest melting point required of any mineral -- 3820 degrees Kelvin -- a melted diamond is uncommon.

Not humanly possible, but if temperatures reach (I will get back to you) it is possible.
It is pressure dependent. A normal atmospheric pressure it sublimates at about 4,330 degrees Celsius.

Yes, but only at extremely high temperatures, something like above 2000 degrees Celsius.

What temperature will a diamond melt?

Diamond mineral has the highest melting point of any mineral: 3820  degrees Kelvin, which is 6416.33 degrees F, or 3546.85 degrees C.

Why can you melt a diamond?

You can melt a diamond, because anything can melt given enough heat. Diamond, however, has the highest melting point of any known mineral: 3820 degrees Kelvin, 6416.33 degrees

What is the melting point of diamond?

At normal atmospheric pressure, the melting point of diamond is 3550 degrees celsius (6422 F). 3823 Kelvin 3550 Celsius 6422 Fahrenheit 3820 degrees Kelvin

Will magma melt a diamond?

The melting point of diamond is sufficiently high that magma would not melt it.

Why does diamonds have a high melting point?

Melting point is the temperature required to break the intermolecular bonds between molecules of a substance. This means that the bonds such as hydrogen bonds and polar attrac

What is the boiling and melting point of diamond?

Diamond, as a rule does not melt or boil under ordinary atmosphere. It simply goes up in smoke (converts directly to CO2 when heated to 800 degrees F in the presence of oxygen
In Physics

Why does diamond have a high melting point?

In a diamond every carbon shares all 4 of its available electrons with other carbon atoms so it consists of 8 carbon atoms, forming a tetrahedral network. This network is very

What happens to a diamond when it melts?

Diamonds' molecular structure is such that when one melts, it transforms into something else, so that what melts is no longer a diamond. Another Answer Diamond mineral has t
