Intersecting sprays of fine Elpidite needles make up the bulk of this hand specimen. These sprays are in very good condition, showing relatively light damage, and the needles therein reach lengths of 0.8" (2 cm). They are too fine and intergrown for one to effectively study their orthorhombic form, and all have a white color, though some show a brown discoloration. Their luster is pearly, and many are partially transparent. A few bits of what appear to be calcite are present, but there is no base rock. The Elpidite sprays glow a relatively bright green color under shortwave ultraviolet light.
