Imperial Jasper and Royal Imperial Jasper
Imperial Jasper and Royal Imperial Jasper are dense, very fine grained and exceptionally hard jaspers, making them both one of the highly prized porcelain jaspers.
Because of their fine grain, porcelain jaspers are harder and take an excellent polish.
Imperial Jasper is found near the border of Jalisco and Zacatecas, Mexico, about 50 miles northwest of Guadalajara. The site covers a large area on a steep slope of a canyon, covered be heavy vegetation.
Royal Imperial Jasper is found over the ridge to the east of Imperial Jasper. It was actually found first as a surface float in the 1980's. The larger deposit of Imperial Jasper was not discovered until the 1990's.
Imperial Jasper forms in veins or large nodules in a host rock. It is known for coming in many colors, but each piece is usually limited to just one or maybe two colors.
The Royal Imperial Jasper is very similar to Imperial Jasper, but is formed in much smaller nodules with a white chalky skin. The Royal Imperial Jasper is also known for is patterns of orbs or "eggs". Imperial Jasper rarely has these patterns, but Royal Imperial Jasper almost always does.
Jasper is an ornamental rock composed mostly of chalcedony, microcrystalline quartz, in association with other minerals, which give it colorful bands and patterns. Jasper was a favorite gem in the ancient world, and the name jasper can be traced back in Hebrew, Assyrian, Persian, Greek, and Latin.
