With a Mohs hardness of 6.5 to 7, almost all forms of jasper take a polish easily. Jasper has no specific cleavage and when it is broken or chipped, it usually has a glassy appearance. Although the majority of jasper is opaque, occasionally it can be found translucent and sometimes jasper will have translucent to transparent inclusions. These inclusions can cause jasper to be marbled, striped/banded, speckled, flamed, spotted, plumed, feathered, dendritic, and multicolored. Several types of jasper appear to have landscapes or scenes trapped inside, these stones are known as "picture jaspers." Basically, jasper is a chalcedony that can be classified as chert when it is dull in both appearance and color. (We will explore chalcedony further, in a future article.)
WS Faculty member Sherrie Lingerfelt used this "ordinary" jasper to create a simple but elegant pendant by using a basic frame wrap in Argentium silver and gold-filled wire.
