Lovely Willow Creek Jasper from just north of Eagle, Idaho (northeast of Boise).

This Jasper actually forms as the centers of giant thundereggs, some as large as 10 feet in diameter. Willow Creek Jasper is known for its subtle pastel colors, squiggly line patterns, and orb patterns. Compared to other fine jaspers, Willow Creek has fewer natural fractures.

Jasper is a form of Chalcedony. Jasper usually refers to an opaque stone, with a solid color or an irregular display of colors caused by various mineral impurities. The named is derived from the Greek word that means “spotted stone”.

Willow Creek comes in mostly pale pastel-pink, green and tan.
