This thumbnail specimen contains a few very small Eudialyte cystals. These crystals do not exceed 0.1" (3 mm) in diameter and appear to be in reasonably good condition- only one of them is visibly damaged. Though they their size and intergrowth makes study difficult, they appear to have good trigonal prismatic form, with well-defined edges and clean faces that have a vitreous luster. Their color is their most noticeable trait- it is a deep red with a hint of orange, reminding me of many garnets that I have seen. The Eudialytes are accompanied by several natrolite crystals of impressive size (up to 0.5" or 1.3 cm in length). Almost all of the natrolites are damaged, and several are broken. However, this breakage allows us to see that the natrolite crystals contain a colorless, transparent "core", which is surrounded by a bright white, opaque "shell". Only a small amount of a dark green host rock is present.
