Our friend Michelle is a geologist, and she has an amazing rock collection. I’ve always enjoyed rocks and gems, and fancied myself a bit of a collector when I was a kid (although my collection was generally just pretty stones I found on the ground). Today she showed me a sample of iron pyrite, popularly known as “fool’s gold”.
This isn’t an ordinary sample, though. It includes two massive cubic crystals, which is really unusual… and probably won’t really fool anyone into thinking it’s gold. Typical deposits of iron pyrite have thousands of crystals like this, but much much smaller and crowded together, making them at least a little more believable as gold.
So cool!
