Agreed with all the above, it is most certainly the Antique Gold from CSA. Note that in their catalog, the pic of the unturned blank is only what it looks like at a particular angle. If you were to turn that blank over 90 degrees and look at that side, it would look like layers of gold and black.
Makes a very, very pretty pen, I sold the first and only pen I made with it fairly quickly (and I oughtta get more).
