A friend let me borrow his humongous gold nugget to look at under my compound microscope. Although it was difficult finding focus, because the microscope looks at very narrow planes, I did like this shot where you can see the ridge in detail.
I think it looks like a planet that I (& Goldmember) would like to visit!
I'm getting my microscope out again soon & love suggestions for what to look at next. Let me know below :)
