Willow Creek Jasper is one of the finest ad most prized porcelain jaspers. It is mined near Eagle, Idaho. The jasper forms in the center of thunder eggs (concretions) that form within rhyolite volcanic ash. High quality willow creek jasper is hard to find. As described by Philip Stevenson, good quality Willow Creek jasper will not have iron pits or stains. I have only selected slabs that do not have these iron pits.
Please enlarge and view the photographs for more detailed views. Shown wet to simulate polish. As with all natural rock, there may be fractures or pits to seal or work around. This material has a lot of pits and druzy cavities between the layers. Each slab has the approximate dimensions listed. I use the longest and widest point and the thinnest, it’s not averaged.
We have worked hard with the lighting and the settings on the camera so that the colors are very accurate. Individual settings may affect color viewing on various devices and I cannot predict what your device will do, but on my computer, they’re dead on for color. I appreciate your business!
