Pyrite Cubes (Loose, in Matrix, Penetration Twins) from Spain - The Geode Gallery
The nearly perfect cubes of pyrite from Spain, specifically 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 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 were 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.

Single Loose Pyrite Cubes from Spain For Sale
Below we offer three different sizes of loose pyrite cubes for sale. Please note - we have all sizes available from as little as 25 cents up to occasionally $40 and $50, with the change in price a DIRECT function of the size of the cube. If you are building a graduated set of cubes from smallest to largest, and need a certain size, provide us with a precise measurement of the edge of the cube and we will let you know the price for a cube of that size. The loose cubes below are our most popular sizes.

#SPPYR 01: Single 2.1 cm (0.85 inch) pyrite cube in a 7.5 x 5 cm (3 x 2 inch) matrix. Flat area at upper left where another cube was at one time but has since been removed. Displays with no assistance needed. $15.00 |
#SPPYR 02: Single 2.5 cm (1 inch) pyrite cube perched on host matrix measuring 7 x 3.5 cm (2.8 x 1.4 inches). A little unstable for display on its own without assistance. $15.00 |
#SPPYR 03: Slightly flattened 1.8 x 1.5 cm (0.7 x 0.6 inch) pyrite cube perched at the top of a 7.5 x 6 cm (3 x 2.4 inches) matrix chunk. Needs assistance to display as shown here. $12.00. |
|
#SPPYR 04: Single 2.4 cm (nearly 1 inch across) pyrite cube in a 5.5 x 4 cm (2.2 x 1.6 inches) matrix piece. $12.00 |
#SPPYR 05: Single 1.6 cm (0.65 inch) pyrite cube
positioned at the top of a 7 x 4 cm (2.8 x 1.6 inches) matrix chunk.
Another cube was likely attached to the upper right corner of the pyrite
cube, thus the slight contact area as the photos show. $10.00 |

#SPPYR 17: Two 2.1-2.2 cm (0.9 inch) cubes are positioned in their host matrix along with several smaller cubes barely sticking out of the matrix - one of these is evident in the top photo at the bottom center of the matrix. I count at least 5 small cubes barely peeking out. Overall measures 11 x 8 x 4 cm (4.3 x 3.2 x 1.6 inches). Does need some assistance for maximum display. $25.00 |

#SPPYR 22: Two pyrite cubes (2.2 and 1.8 cm or 0.85 x 0.75 inches, respectively) are nestled in their marl matrix. The bottom left cube has been repaired or glued back in its original spot. The matrix measures 11 x 5 x 2 cm (4.3 x 2 x 0.8 inches). $22.00 |
|
|
#SPPYR 24: Three cubes, two on the front and one on the back, are located on a marl matrix base. The two front cubes measure 1.75 and 1.8 cm (0.7 inches) and the back one 1.3 cm (0.5 inches). Specimen will sit flat for display but will need assistance to sit upright as shown in photos. Matrix measures 12 x 9 x 3 cm overall (4.7 x 3.5 x 1.2 inches). $25.00 |

All of the following specimens are natural pyrite penetration twins. These types of specimens are not matched for their quality scientifically and aesthetically anywhere else on Earth on a regular basis and almost define perfection in crystallography with the sharp twinning and crisp edges. Again, these are all natural! They have just been removed from their host matrix.
