This specimen has two clusters of bornite. The largest may be a single distorted octahedral crystal and is irridescent in shades of blue and violet. The smaller is a cluster based on a very nice elongated (but incomplete) octahedron with several smaller clusters attached. This crystal is irridescent in blues but mostly purples, but also displays some reds, yellows, and greens (at least under a loupe). These crystals rest on a druze of colorless quartz crystals, which in turn cover a complex rock containing at least 4 minerals.
