How long does it take for lava to cool underwater
Lava cools very quickly at first forming a thin crust that insulates the interior of the lava flow.
As a result, basaltic lava flows can form crusts that are thick enough to walk on in 10-15 minutes but the flow itself can take several months to cool!.

Can lava melt diamonds
According to Wikipedia, the temperature of lava is between 700 and 1200 °C (973 to 1473 K). The melting point of Diamond at about 100,000 atm is 4200 K, which is much higher than the temperature of lava. So, it is impossible for lava to melt a diamond.
Why does lava cool faster in water
2 Why does lava cool faster in water than in air? Lava flowing out of an erupting volcano is very hot. As lava flows, it loses heat and begins to cool slowly. The lava may flow into the ocean, where it cools more rapidly.

Leo Adonis had chosen to die by jumping into the volcano. Investigations were conducted and concluded that the man did, in fact, commit suicide-by-volcano. He jumped to his death and landed on the outer rim of the volcano crater, rather than the lava itself.
What happens if lava touches water
When lava meets the sea it cools quickly while boiling the ocean into steam. The billowing steams clouds can be deadly as they contain small glass shards of fragmented lava and acid mist from sea water. … When lava hits seawater at temperatures of around 2,100 degrees Fahrenheit it heats the sea water dry.
