That really depends on the exact pressure. Look at the Wikipedia article "Carbon#Characteristics" (article "Carbon" section "Characteristics"). Especially, take a look at the phase diagram.
Diamond is a form of carbon. Carbon melts at 8300 °F but only if held under pressure of around 1600 psi.Diamond melts at 3,820 degrees Kelvin, which is the highest melting point of any mineral.
Yes you can but it would take a very hot temperature for the diamond to melt. Not any normal hot temperature. Diamond has the highest melting point (3820 degrees Kelvin, or 6416.33 degrees F.)
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). Its melting point (at very high temps) is roughly 3500 degrees Celsius (very hot), but you need extreme pressure to achieve it (otherwise, it converts to CO2). Its melting point is the highest of all known materials, in large part because of the covalent bonds and the fact its atoms (carbon) are quite small and thus pack very tightly.
Diamond sublimates at apprx. 3726.85C.
One substance that has a high melting point is diamond.

The melting point of copper is 1084,62 0C. Diamond burn on heating in air; under pressure of a inert gas the melting point may be approx. 4 000 0C. This depends on the type of glass; also glass hasn't a true melting point. Glasses are melted over 400 0C.

The solid element with the lowest known melting point is helium, with a melting point of approximately -272.2°C (-458°F) at atmospheric pressure. However, helium remains a liquid at normal atmospheric conditions; it only solidifies under extreme pressure. In terms of elements that can exist as solids at standard pressure, the element with the lowest melting point is francium, which has a melting point estimated around 27 °C (81 °F).

If my math is correct, you're asking for the melting point at a distance of about six miles above sea level -- which means you're probably air-born. The melting point of diamond is 3,820 Kelvin. So assuming you have the gear that can produce that temperature at that altitude, you could melt a diamond. Given the altitude, the Kelvin reading might be a little lower.
Diamonds have a melting point of around 3820 degrees Celsius. At this temperature, the strong covalent bonds that hold the carbon atoms together in a diamond structure break, allowing it to transition from a solid to a liquid state.
The melting point is not changed by pressure. It is still over 32O
a diamond's melting point is so highmagma will not melt it
The pure substance with the highest melting point at 1 atmosphere of pressure is tungsten, with a melting point of approximately 3,422 degrees Celsius (6,192 degrees Fahrenheit). This property makes tungsten particularly valuable in applications that require materials to withstand extreme temperatures, such as in aerospace and electronics. Its high melting point is due to the strong metallic bonds present in its crystal structure.
