Do diamonds melt in lava?

Can the sun melt a diamond?

However, you needn’t worry about leaving a diamond in the sun. It would take a temperature of 700-900°C before it started to burn, since the carbon atoms in a diamond are in a tight three-dimensional array that’s very hard to disrupt.

What happens when you melt diamond?

At ~700 degrees Fahrenheit the diamond will start burning. This will produce Carbon Dioxide and change the structure so that it is no longer a diamond. As diamond is made of Carbon, it would revert back to that form while losing its mass to the production of CO2. This is due to the presence of Oxygen.

Are old diamonds more valuable?
