IMPERIAL JASPER Is found in deposits over a wide area in Guadalahara, Mexico. This jasper forms as nodules and usually has a soft white chalky exterior. The colors shades of pink, red, and green are what makes Imperial Jasper such a beautiful and dramatically versatile stone. The spider web patterns on the Jasper are known as streamers which form when the jasper is fractured, which results either from stress or shrinkage. These fractures are then filled in and sealed with more jasper. An endless variety of patterns can result with subtle shifts in the color of the jasper filling these voids.
