Here's why:
* Melting Point: Diamonds have a very high melting point of around 4000°C (7232°F). This is much higher than the temperature of most lava flows.
* Lava Temperature: Lava from active volcanoes typically ranges from 700°C to 1200°C (1292°F to 2192°F).
* Carbon Transformation: While a diamond is made of pure carbon, at extremely high temperatures, it can transform into other forms of carbon like graphite.
In summary: While diamonds are incredibly hard, they are not invincible against the intense heat of lava. The high temperatures of lava flows would be sufficient to melt a diamond.
