There is only a single volcano that actively erupts diamonds. Not only does this make the Avachinsky volcano unique, but the type of diamond it erupts is equally fascinating, being known as carbonado. These interesting black diamonds are found within the lava flows of this volcano although the exact reason why they are present is unclear. This video will discuss the Avachinsky volcano, diamond formation, and two potential causes of how these diamonds reached the surface. NOTE: Collecting at this volcano is most likely not allowed/is illegal. Please do not collect at the Avachinsky volcano unless you receive permission to do so from the relevant local authorities.
