Geological Formation and Diamond Origin
Volcanic Roots
The park sits above an eroded volcanic pipe where kimberlite or lamproite magma once surged toward the surface, carrying diamonds from depths of 100 miles or more before cooling and solidifying.
Erosion and Accessibility
Over millions of years, weathering and stream action broke down the volcanic rock, concentrating small diamonds in soils and gravels that visitors can easily sift through today.
Search Techniques and Visitor Experience
Field Searching Methods
Most guests start by walking the designated search field, using visual scanning and handheld screens to separate soil from potential crystals, then panning or dry screening to reveal hidden gems.
Water Washing and Sifting
Visitors often wet down soil in designated areas, using a gentle swirling motion in hand screens to wash away clay and loosen diamonds that may be hiding in the gravel layer.
