Pyrite has the nickname "fool’s gold" because the brassy yellow color and chunky appearance have fooled a lot of prospectors looking for gold. It is a brittle, metallic mineral and is more than 50% sulfur in composition. The surface of pyrite is often grainy, although cubes are also common, as with this particular variety of pyrite. Astoundingly, these cubes are natural formations, taken straight from the earth, still embedded in the limestone from which they were excavated. The unique and striking cube form is great for classroom lessons, as it is doubtful that students have seen natural formations like these that look so much like the result of artifice. This also is definitely a piece that will stand out in any professional collector’s collection!
Note: Please be aware that this is a natural mineral and as such each piece is one of a kind! The one you receive may not be exactly the same as the one pictured but it will be similar. Price is per each piece. They come in irregular shapes, sizes and weights.
