Beautiful leopardskin jasper from the state of Chihuahua, north western Mexico.
Leopardskin jasper is widely described as an orbicular jasper with particularly distinctive markings. The colour can vary from light shades of brown to the deepest shades of red.
The name jasper is often used incorrectly to describe any colourful decorative stone that can be highly polished. Using 'jasper' instead of the geological name makes it more saleable because it's a name people are familiar with.
Leopardskin jasper is correctly known as orbicular rhyolite which explains why the name leopardskin jasper is used instead. Orbicular refers to its orb-like or spherical markings.
