This Brazilian Agate is a tangerine color with subtle banding that can be seen with the right lighting.  I'm tempted to say it is carnelian but I think Ed corrected me already once. 

Ed Orekar of California cut, handshaped and polished this beautiful stone.  I have wire wrapped it in 14k gold filled wire.  I have coordinated a pair of earrings with beads and I will provide a link when I get those listed.
