Jasper is an opaque variety of microcrystalline silica. Silica includes all compounds of SIO2 with different amounts of water and is therefore considered a variety of quartz. The three main varieties of silica are opal, jasper and chalcedony.
Jasper is recognized by its granular microcrystalline structure and by the eye by its opaque appearance and conchoidal fracture.
Because there are various origins, since they are associated with very different rocks, each one will show a characteristic pattern. Regarding the colors, the varieties are infinite due to the small impurities mainly of iron and manganese, and also of other elements.
Jaspers were highly appreciated by man already in prehistory where they were used to create arrowheads thanks to their tenacity. Today they are still highly appreciated by lapidaries for their excellent polishing which allows the creation not only of magnificent ornamental objects but also pieces for jewelry such as cabochons and beads and beautiful collection specimens.
The only genetic classification of jaspers that exists today has been carried out by Marco Campos Venuti, graduate in Geology and PhD in Volcanology, widely explained in his book “Genesis and Classification of Agates and Jaspers: a new theory“, for sale on this website.
This classification organizes the types of Jaspers into four large groups based on their origins:
-
Oceanic Jaspers (organogenic sedimentation): flints, abyssal jaspers and banded Iron Formation (BIF).
-
Volcanic Jaspers (silicification of volcanic rocks): stratified jaspers, massive blocky jaspers and rhyolitic jaspers.
-
Pseudomorphic jaspers on fossil (silicification of fossils).
-
Chemical Jaspers (chemical precipitation): orbed jaspers, brecciated jaspers and jasp-agates.
Owyhee Picture jasper is a volcanic type, stratified on volcanic tuff.
This is one of the more popular jaspers used for designer cabochons, because of its glossy polish and its amazing depictions of desert scenery.
They are recognized by their natural drawings in earth tones, ochre tones, intense reds on a whitish, cream and other light colored base.
It is found in the Owyhee Mountain of Eastern Oregon, USA.
