About Jasper
Historically the name has long been used for an opaque to slightly translucent, generally red or brown to variably coloured, impure chalcedony or microcrystalline chert, usually containing abundant fine inclusions of hematite, iron hydroxides and other minerals. It is typically associated with banded iron formations.
It has also been used informally by lapidarists for many other opaque lapidary materials, including some igneous and sedimentary rocks.
