Sharply crystallized examples of this species are very rare, and this is the first I personally have handled. This is the type locality, from which specimens were recovered around 1900 and identified in 1902. This is a rare magnesium, aluminum oxide, borate silicate and here occurs in lustrous, slightly translucent, sky blue crystals, to 1.5 cm across. This ENTIRE CLUSTER is composed of sharp tabular crystals, although with some contacts at the edges.
UNIVAZ-126 - Grandidierite - $ 750 SOLD Vohibolo, Behara, Amboasary, Anosy Region, Tulear, Madagascar thumbnail, 2.4 x 1.8 x 1.3 cm ex. University of Arizona
A rich example of this very rare species, composed of solid massive grandidierite with crystal faces on one side. Actually, it is one of the more attractive and well-crystallized examples of this material that I have seen, despite rough edges and a massive back. From the collection of the University of Arizona Museum, purchased in 1975 from a contemporary find here at that time.
