These Hematite pseudos when they are good have an incredible form. This specimen is one of the very best I have seen, perfect, complete all around and with well developed faces. Marcasite is an unstable mineral that can decay over time but these pseudos are perfectly stable. The detail of growth is perfectly preserved and presented on all the faces and the form looks like a leaf. These are sporadically available but very few are of this size and sharp development. A superb pseudomorph and an very esthetic piece.
Hematite PS after Marcasite

2.9 x 2.8 x 2.7 CM (small miniature/ large thumbnail (toenail))
A perfect complete radiating pseudomorph with super form. I consider these Pseudomorphs from Egypt some of the best values in minerals today. They are sporadically available on the market and sometimes (as in this piece ) have a highly esthetic form. This shows perfectly well the original crystal structures. A choice example, no damage or contacts.
