The stones in Puma Punku are made up of granite, and diorite, and the only stone that is harder that those two, is the diamond. If the people who built this place cut these stones using stone cutting techniques, then they would had to have used diamond tools. If they didn't use diamonds to cut these stones, what did they use? Each stone weighs about 800 tons and the nearest quarry is 10 miles away. How did they move these blocks?
