sloth Posted March 12, 2018 Share Posted March 12, 2018 Here was a nice surprise. I picked up this fossil cluster of barnacles and noticed a nice layer of agate underneath! When I processed the photo I took of it, I saw that the light from my flash dispersed giving this rainbow effect. It's very small but now when I hold to the light I can see the little rainbows! I heard this process is called diffraction grating. I would like to polish the agate but I think the rainbows will go away once the material is flattened.

Auspex Posted March 12, 2018 Share Posted March 12, 2018 How neat! Could that be calcite, rather than agate?
