#APicADay 2020: Day 317

 There was another day of poor weather, and no chance for a walk.

Today's image:

Fuji X-T3 with XF 55-200 @ 200mm, f/11, 1/250 s, and ISO 160

I don't know what mineral this is, nor why it was turned into a polished sphere. (Or mostly a sphere, anyway.) But the light does some interesting things in it.
