Violet crystal is
fluorite ( see below for spectra)
Crystals 4 and 5 are Fluoro-Arfvedsonite or Eckermanite.
Green crystal 6 is Aegirine.
Clear crystals are Microcline.
This spectrum of crystal 10 is of low intensity. It
seems to be the prismatic Rosenbuschite.
Heavily altered crystals giving more complex spectra.
Position 14 gives a mixed spectrum of nepheline
and mica + 2 extra peaks, one of them could be analcime. Material at
spot 13 is a mica + 1 extra peak. This spectrum 13 could be interpreted
as a mica + analcime.
Spectra of Violet Fluorine. These are raw spectra
without any baseline correction. Fluorite has normally only one line in
the Raman spectrum at 322 cm-1. The spectrum of a transparent
crystal is so (black curve). Violet fluorite crystals have different
spectra which change according to the intensity of the color as also
published in the literature.
