The nearly perfect cubes of pyrite from Navajun, La Rioja, in northern Spain, are very popular given their shapes.  Only a few other locations on Earth produce similar specimens but nowhere else than in this quarry in Spain is there such an abundance and the quality consistent over time.  Everyone asks, "Are these natural"?  The answer is YES.  All of the specimens you see below occur naturally!  The only thing that has been done to them is the dust/matrix was cleaned off and in the case of some of the matrix specimens, the cubes have been repaired (glued) into their original position in the host rock but nothing has been fabricated other than how it naturally occurred.  While repaired mineral specimens do detract from the value in most cases, this is one of the few specimen types that repairs are acceptable given the situation.


Below you will find a selection of loose cubes, penetration twins, and matrix specimens.  We acquire our pyrites DIRECT from Spain - you cannot get any more direct unless you went and collected them yourself.  The result is comparably much lower prices and consistent high quality.  If you do not see what you are looking for, please contact us as we have a large supply of all specimen types in all sizes available.


SIZING:  All matrix and penetration twin specimens have a letter or letters after their product name below which refers to the size of the specimen.  T = Thumbnail (2-3 cm or 0.8-1.2 inches);  M = Miniature (3-6 cm or 1.2 to 2.4 inches); SC = Small Cabinet (6-10 cm or 2.4 to 3.9 inches), C = Cabinet (10-15 cm or 3.9 to 6 inches), and LC = Large Cabinet (15+ cm or 6 inches and larger).
