Sphene-fluorite

Sphene-fluorite

This is actually a color shot. The crystal at the end of an imaginary line from the tip of the prism shaped crystal and the bump on the black blob, is actually amber in color.

In this capture, the amber crystal is in the upper left point of power.  I initially thought that might be the subject of this sample.  Sphene is also known as titanite.  The amber crystal could be Sphene.

The Fluorite is possibly the prism shaped crystal.  I could find nothing on this sample which would fluoresce under long wave or short wave UV light.  This sample is an enigma to me.

The first image is 3.57mm and 6.58X on the sensor.  This sample is from Octahedren, Arkansas.

Fluorite which is optically clear can be made into high quality, low dispersion, low chromatic aberration lenses.  Those lenses are expensive.  I don't think that I own any.
