Spiderman Jasper Slabs
Spiderman Jasper has orange spiderwebbing against a black background. It's
unusual and cuts great stones. The orange spiderwebbing are often weak points.
So, care must be taken not to put stress on this material when cutting.
Fabulous stones is the reward for patient cutters. Jasper is an opaque,
microcrystalline form of quartz. As with any microcrystalline quartz, it
is hard and takes an excellent polish with cerium or tin oxide.
