Home > Ojuela! – June 8 > MS1225 Legrandite


Legrandite is a hydrous zinc arsenate originally found elsewhere in Mexico (Drugman et al. 1932). Using material from Ojuela, Finney (1963) determined the space group symmetry and corrected the chemical formula. The crystal structure was solved independently and contemporarily at the University of Arizona (McClean et al. 1971) and at Moscow State University (Pushcharovskii et al. 1970). The Ojuela mine has produced the largest known crystals so far, reaching 27 cm!, found in 1977

This is an attractive thumbnail specimen of legrandite, featuring two overlaping crystals, one 15 mm long, and the other 12 mm long, perched on matrix. This specimen shows the crystal habit typical of the 1977 pocket, but specific provenance information is lacking. Excellent thumbnail specimen. Competition quality.
