A great example of this iron tungstate-- this one has multiple sharp back crystals sitting on matrix, including a twin that sids sideways on the top-- you usually don't see the twins on matrix. Some edge chipping, but still a good, sizable example of this material from a find made around 2 years ago. Quite good for the price....
