The above photos were taken in natural light. In the photo on the right specimen was rotated about 135 degrees ccw.
These two photos were taken from about the same distance as the first
photos using
long wave ultra violet light. The left one is about the same orientation
as the one above it. The one on the right is about 45% clockwise of the
one above it.
Two closer photos under Uv light. Crystal structure may be seen. Only a small part of the specimen is shown here.
Close up of some of the exceptional crystal structure. These are much brighter than in the photos!
More close up crystal structures. There are thousands of such crystal clusters!
