Hematite after Goethite Beryl save the tiniest of “Wilbers”One of the few specimens of this material that Ive encountered. This piece is essentially a pseudomorph of one iron oxide replacing another (i. e., Hematite and Goethite). This foliated group of good sized crystals is an excellent representation of a material that is rarely available on the market. My father acquired this piece from his Amazonite collecting partner, Clarence Coil in 1975. Ex. Clarence Coil collection Specimen# CO712B191
