Not really it can not because a diamond is really solid
Anything can be melted by the sun it is really hot.
Hmmmmmmm. that's a very hard task. You'll lose a lot of money. Consider keeping it solid. There is a way, but I implore that you don't melt the diamond.
melted as used in a sentence.. "The ice melted from the hot sun."
Diamond Sun was created in 1987.
The first diamond was successfully melted in 2011 by a team of researchers at the Dresden University of Technology in Germany. This was achieved using a special high-pressure, high-temperature process.
Sorry but no.
Icarus
No, not if the diamond is on earth, and not closer to the sun.
When melted diamond cools it solidifies back into a crystalline structure, forming a solid diamond again. The cooling process allows the carbon atoms to reorganize and form the strong covalent bonds that make diamond one of the hardest materials known.
When a diamond is melted, it typically transforms into a carbon vapor or liquid state rather than becoming a recognizable molten form like metals. The extreme temperatures required to melt diamond (over 3,500 degrees Celsius or about 6,332 degrees Fahrenheit) cause it to break down chemically, often resulting in a blackened, amorphous carbon residue rather than a shiny, liquid state. As a result, melted diamond doesn't retain its crystalline structure or appearance.
Diamonds don't melt, so your question doesn't have an answer.
Icarus is a part of Greek Mythology. Icarus tried to escape from Crete with wings made of wax from his father. Icarus didnÍt hollow his fatherÍs instruction to not fly close to the sun and when he did his wings melted and he fell in to the sea and drowned.
