This is a somewhat unusual example of small, but free growing, crystals of normandite. The saample was conformed via qualiative EDS (to the extent that that is possible). See the child analysis "photo".

This is a qualitative scan for an unpolished sample, but it seems like a pretty good match.

This is a stereo child photo showing more of the normandite. These blades are still growing freely in a cavity, but they are more tightly packed in radaiting sprays. These crysatls are also more "robust".

This is a child photo showing part of one side of the specimen. The normandite laths shown here are mostly more "typical" in that they are embedded in matrix. But the matrix isn't the usual nepheline-syenite. The laths transition to free-growing in the upper left quadrant. Note: This photo uses half the magnification of the others.
