No. As the pressure at the relatively shallow depths where volcanoes occur is not high enough to form diamonds. However it is true that volcanic eruptions can cause diamonds to be erupted onto the surface but these diamonds were already formed at much greater depth.
ummm volcanic rock? but really its black rock and its all over near the hawaiian volcanoes! :)
A caldera may form inside the crater of a large volcano. A caldera is a large depression caused by the collapse of the summit of the volcano following a massive eruption. It can be several kilometers in diameter.
How did the volcano kohala form
Diamond Head volcano in Hawaii is not considered extinct; it is a dormant volcanic cone. It last erupted around 150,000 years ago. The volcano's eruptions were relatively small and not known to have caused significant damage.
Magma is inside the volcano, and it becomes lava when it comes out. :)
magma flows up to form the eruption

Plutonic rocks are formed by the inside of the volcano through slow cooling of magma.

Volcanoes form because when the magma flows up through cracks inside of the earth's mantle then the volcano is formed.
Volcanic rocks form on or near Earth's surface from the solidification of magma (molten rock) that has erupted from a volcano. They can also form when lava cools and solidifies quickly in underwater environments, such as in ocean ridges or volcanic islands.
Over time the magma chamber found inside volcanos is cut off from the mantle by tectonic plate movement. Without constant exchange of hot magma from the mantel to replace the colder magma in the volcano, (convection), the magma inside the volcano hardens into igneous rock.

Yes, lava is on the outside of a volcano. Magma is on the inside of a volcano.
Magma inside a volcano can become a lava flow outside when pressure builds up inside the volcano, causing the magma to erupt through the volcano's vent or fissures. As the magma reaches the Earth's surface, it is then referred to as lava. Once outside the volcano, the lava can flow downhill and solidify to form igneous rock.
