Allot of plume agate ive worked that comes from the large occruace in the Oregon/Idaho boarderland can have a driection. This piece of Maruy's driection was at a slant to the general driection the moss was arraged under it. (plumes are the brown/yellow color, moss the red). If you've ever heard the term "angle wing" when it comes to plume agates, these are almost always showing a growth driection on a sperate aixs then the plumes growth point.
however, material like the graveyard we just
talked about here shows two examples of how cutting effects the pattern, based on the growth of the plume shape. If you look at mine, the plumes are not as narrow as they are in Seth's peice. That is becasue often that plume is more like a fan shape.
There are many plume type agates from around the western US that reqiure speical attention to proper cutting orientation in order to even produce a nice example of the plume, becasue then it can turn into what looks like moss to most. lowering the value in some markets. However, thats always whats nice about high grade regency plume agate, cutting it both driection(there is three ways to cut it actaully), produces such fine detail and patterns.
