Can acid melt a diamond?

No, acids cannot dissolve diamonds, for the simple reason that a diamonds carbon atoms are too tightly packed together for the Hydrogen ions to be able to dissolve the substance.

What is the strongest metal on earth?

tungstenIn terms of tensile strength, tungsten is the strongest out of any natural metal (142,000 psi). But in terms of impact strength, tungsten is weak — it’s a brittle metal that’s known to shatter on impact.

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.
