Swazi Bloodstone - Brecciated red jasper in green chert which looks grey until you wet the stone. Some has golden pyrite spots which polish to a metallic shine. Can have large or small patterning. It comes from Swaziland in Southern Africa.

This Swazi Bloodstone slab measures 5-1/4"x2-1/2x3/16".  It has some natural internal fracturing that I would work around when designing your cabochons.  You will be able to get numerous colorful slabs from this slice.  The photo was taken with the slab dry and indoors.
