Why? Diamond has very low thermal expansion, so no risk of stress/embrittlement/cracks from uneven heating.
Or you mean it'll catch fire? Also not a concern. That is supposed to happen at a temperature well above anything useful for cooking.

Should be safe on electrical stoves though.
There are some heady boundary-layer effects and temperature/temp-conductivity gradient physics involved here. For simplicity sake, consider a plastic [1] bag full to the brim with water, held over open flame. Will bag melt (oxidize, erode)?
[1] polyethylene melts around 120-ish °C and ignites around 220-350 °C (sources vary)
