I am going to start this off by saying that none of these large pyrites look nearly as good in pictures. The faces on these pieces are practically mirrors, and the three dimensionality of these pieces, combined with the many reflections makes them nearly impossible to photograph.
This is a very large cabinet piece, from the spectacular find made approximately 2 years ago. It does have a couple spots of damage, though is on the whole better than 98% of what I've seen-- and that includes much smaller pieces. When you have larger ones like this, there is usually all sorts of damage-- and when you consider how delicate the corners of these crystals are, combined with their weight, and the fact that they first have to be extracted, and are then put together in large sacks and hauled out of the mine-- it is remarkable that anything can survive this intact.
Pieces from this find were notable for the exceptional luster, and this one has a rather large single crystal nicely standing out above the main cluster.
This is equally good as a decorator item or as a mineral specimen-- it is large and garbs enough attention to be the former, while also being clean enough to be great as a specimen.
