Crystals

[pwnell]

The first two images are from melts / solutions I made. What is different from my other pictures of these crystals before, is that I could photograph them now at 40x revealing some details I could not see earlier. Also, reflected polarised illumination reveals different structures and patterns than transmitted polarized light.

I have a piece of Calcite crystal which I photographed under UV excitation, where it shines bright white / rose depending on the UV wavelength used. I thought maybe I can see something nice under the microscope as well. It indeed did fluoresce but the beauty does not come from what I had expected. Once I switched over to reflected polarized illumination and my LWD PlanApo 40x/0.6 objective (that has correction for 0 - 2mm) I could image these strange formations deep within the crystal itself.
