The largest known single, naturally occurring stone in the world is Ausangate, located in the Andes mountains of Peru.

Here's why it's considered the largest:

* Size: It's massive, with a volume estimated at over 1,000 cubic meters.

* Formation: Ausangate is a granite monolith, a single piece of rock that formed over millions of years.

* Location: It stands tall as a sacred peak in the Andes, a popular destination for trekking and mountaineering.

While there are other large rock formations, like Uluru (Ayers Rock) in Australia, they are not single stones like Ausangate. Uluru, for example, is a monolith, but it's formed from a single type of rock that has weathered over time.
