Kimberlite, the rare volcanic rock known for bearing diamonds, has also been transformed into stunning outdoor sculptures around the world. Among the most famous is "The Big Hole" in Kimberley, South Africa - not just a massive open-pit mine but also home to impressive kimberlite rock formations visible from viewing platforms.

In Canada, the "Diavik Kimberlite Pipe" in the Northwest Territories features naturally sculpted kimberlite formations visible above ground. Artists have also created remarkable works like the "Kimberlite Sentinel" in Arkansas, USA - a 12-foot tall abstract sculpture polished to showcase the rock's unique texture.

Russia's Mirny Mine displays dramatic kimberlite walls in geometric patterns, while Australia's Argyle Diamond Mine features striking kimberlite formations that resemble modern art. These natural and man-made creations demonstrate how this extraordinary geological material can become breathtaking outdoor art.

The largest kimberlite sculpture may be Botswana's "Orapa House" facade, where architects incorporated massive kimberlite boulders into the building's design. Each of these works tells a story of Earth's geological history while creating visually striking landmarks.
