Small black grains of Perrierite-(La) mixed with similar appearing Loparite-(Ce), pretty hard to distinguish between them. Although not the type location for Perrierite-(La), this is the first, recorded location for the species. Also present in the specimen are larger, elongated crystals of Aegirine and a reddish, broken crystal of Pyrochlore. The matrix is Calcite which exhibits cleavage planes and a slight green color in places.
Condition: Good
Flaws: Essentially massive material.
