Enhanced galena

My photos of this piece didn't turn out particularly well, so I decided to play around a bit with my Olympus software, sliding the Unsharp Mask up to midway. I don't see much improvement, but I think the effect has quite a bit of potential.

Similar to realgar (blipped a couple of days ago), galena is also toxic, being a sulphide of lead. I think/hope that it's just a wash-your-hands-after-handling kind of toxicity. Galena is the dull silver metal. The golden stuff might be pyrite, but I'm just guessing.
