Yellow Feather Jasper Slab

Nature's Own Brushwork in Stone

This striking Yellow Feather Jasper slab is a natural masterpiece. Beautiful feather-like dendritic inclusions — formed by iron and manganese oxide infiltrating silica-rich sediment over millions of years — spread across a warm golden yellow-beige matrix like ink on parchment. Nicknamed “Featherstone,” no two slabs share the same pattern.

Polished smooth with clean edges, it’s ready for display, wire-wrapping, or cabbing — a prized piece for collectors and lapidary artists alike.
