#SPYR 49:  9.5 x 6 x 4 cm (3.7 x 2.4 x 1.6 inches) - $20

No less than three pyrite cubes are perched on a marl matrix base.  Tough decision with this one on how to best display it.  Cube size is 1.4 - 2 cm on edge (0.5 to 0.8 inches).  Some contacting to one cube on back where another cube was joined at one point but was removed, likely during removal.
