I think the article you want is:

Volcanoes don't make diamonds. Diamonds are made deep in the earth's
mantle over 100 million years ago. Only a specific type of small
volcano brings these diamonds to the surface.
"The explosive emplacement of the volatile-rich kimberlite magmatic
fluid results in the development of near surface kimberlite 'pipe'."
