*Thinking a moment* Not too likely no. The melting point of diamond is around 3820 degrees Kelvin. While wood fires get to only bout 313.16 degrees Kelvin…

That is around 3506 degrees short…

Unfortunately, it sounds as if one of your friendly neighborhood rescue workers may have decided that missing diamond earrings would be the least of your worries and taken them home to a significant other (or to a pawn shop). Hopefully, with all of the loss you sustained, you are insured and can make a substantial (if not full) recovery, including the amazing disappearing earrings. Best of luck to you.

Of course diamonds can burn; they are pure carbon and the metal holding the diamonds can melt at a much lower temperature. That said, the local temperature at the diamond would have to be quite high (perhaps 1560 F) in free air to burn. Perhaps they survived and could be sifted out of the ash if you could find the remains of whatever contained them. Good luck.

I wouldn’t think so….diamonds are composed of coal with temperatures well over 6000 dfh. and I can’t see a fire with oyxegen would get that hot. They are in there somewhere.

There is no chance that diamond(the purest form of carbon)melt in a house fire.

The melting point of diamond is the highest of all known natural substances, over 3800 K, which converts to 6,380 degrees Fahrenheit. (Carbon’s tetrahedral network solid structure is responsible for the high melting point.)
Although the diamonds themselves did not melt, the earrings’ metal may have melted, depending on what it was. In any case, your earrings are small and would be difficult to locate in the ruins of a burned down house. If they haven’t been stolen, they’re definitely still there.

Nope, not unless your diamonds were in hell… or plastic.
If you can’t find them they were fake and melted or if they are real, then they are probably just lost.

Diamond, crystal form of pure carbon, hardest of all substances, prized as a precious gemstone. The English name is derived from the Latin word adamas meaning “invincible”. Totally colourless diamonds are very scarce; most contain varying traces of yellow or brown. Yellow is caused by the presence of nitrogen within the crystal structure and brown is associated with plastic deformation. Grading diamonds for colour is done by specialists using comparison sets of defined “master stones”. The record auction price bid for a colourless diamond, graded as the top, very rare white (“D” colour) and internally flawless gem was made in 1995. The Star of the Season, a pear-shaped diamond of 100.10 carats, was sold for US$16,548,750. “Fancy” colours such as fine reds, blues, greens, and pinks command the highest prices per carat. The diamond symbolizes love, endurance, and lasting value.

Like graphite and charcoal, which is non-crystalline, diamond is an allotrope of carbon. It is the structure of its crystal lattice and the uniform bonding of the atoms within that together produce its exceptional optical and physical properties. Its scratch hardness is beyond that of all other materials. On the Mohs scale of hardness, diamond measures 10. Measured on a sclerometer, which moves a diamond across a surface under pressure until a scratch is produced, diamond is shown to be 140 times more scratch resistant than corundum (ruby and sapphire), regarded as the next hardest gemstone. In fact, only diamond will scratch diamond.

Another important physical property different from hardness, although often confused with it, is toughness. This is the ability to resist disruption under pressure. A diamond in a vice will withstand extreme pressure and puncture the steel jaws. Indentation tests indicate that to dent a diamond requires a pressure of 8,000 kg/mm2, whereas corundum will be dented under a pressure of only 2,200 kg/mm2. However, diamond is not so resistant to shock. It can shatter under a heavy blow from hard materials.

Diamond crystallizes in the isometric system with octahedra (eight faces) and rhombic dodecahedra (12 faces) shapes commonly occurring, but several other crystal types are known. Among these are cubes, variations of octahedra—including the hexoctahedron (48 faces)—twin crystals, and maccles. The latter are octahedrons where one half of the crystal lattice is rotated through 180 degrees relative to the other. In processing “cuttable” diamonds, such knowledge has practical implications; cleaving can only be done cleanly along planes parallel to octahedral faces.

Important optical properties of a polished diamond—other than its colour—are seen in its high refractive index (2.4175), high degree of clarity, colour dispersion, reflectivity, adamantine lustre, and scintillation. The total effect, known as brilliance, depends entirely on the diamond’s “life” and “fire”. The purpose of “life” is to return a maximum 83 per cent of light back to the eye, without allowing it to escape through the diamond’s back or sides. “Fire” is the display of spectrum colours caused by white light reflecting internally, before it is refracted back to the eye. When either the diamond is moved or its observer moves, “fire” describes the darting flashes of spectral colours that are visible.
