This thumbnail piece appears to be made up mostly of Eudialyte by weight. Though the material is crystalline in nature, no complete crystals are present. The only evidence of crystal form is a single flat face on one end of the piece- all other surfaces are uneven. The Eudialyte has the standard red color with a hint of violet and a dull pearly luster on its one intact face (the broken surfaces are vitreous). Though it is essentially transparent, the material is extremely internally fractured. Collected in 1993 for the Geological Survey of Canada, documentation shows that this piece likely also contains agrellite, vlasovite and mosandrite.
