The Richard M. Geiger Collection

Collected 2003. Crystals to 4.4 x 0.7 cm. Jordi: A dramatic floater made up of a group of prismatic, brilliant crystals with sharp faces. Near the ends are clear colorless areas that contrast with the intense blue of the rest of the crystals, some of which are doubly-terminated. There is a mineral present in small coatings, especially near the terminations on some crystals, which fluoresces bright green in shortwave ultraviolet. ---- Photos ©2006 Richard Geiger Specimen acquired from Fabre Minerals
