The mineral itself actually belongs to a calcite group of \"related carbonates\" that are \"isomorphous\" with each other. All members of the group crystalize in triangular formations, have perfect rhombohedron cleavages, and in transparent rhombohedrons, display strong double refractions. Aragonite and Calcite are similar in chemical composition (polymorphs) but are structured differently, with Calcite forming triangular crystallization and Aragonite forming orthorhombic crystals (three axes planes, at unequal lengths, and all three axes 90 degrees to one another. Unique Calcite formations are created inside the caves where calcium rich water penetrates the cavern's limestone enclosure and slowly drips and flows on top of itself, allowing for the formation of unique stalactite and other globular formations to be created. In this slow process, other minerals can intermix with each other, adding to the interest and forming unusual specimens, such as the one displayed.\u003c\/p\u003e \u003cp\u003eA golden yellow to brown, widely occurring mineral sulfide, FeS2, \u003cstrong\u003ePyrite\u003c\/strong\u003e is used as an iron ore and to produce sulfur dioxide for sulfuric acid.

The Pyrite Cubes from Navajún were formed during the Mesozoic Era, at the end of the Jurassic Period, approx. 120 million years ago. They originated within the sediments of a large delta that covered the Cameros Sierra. The Pyrite was contemporary to the dinosaurs that lived in the same region, the fossils of many of which have been found near the mine. The matrix material is mostly a very fine-grained sedimentary marlstone (clay and calcite), Although Pyrite is relatively abundant in nature, it is very rare to find single crystals fully finished with the perfection and shine of those from Navajún, making it highly appreciated by collectors all over the world.
