Basalt Quarry, Ambariomiambana, Sambava District, Sava (Northeastern) Region, Antsiranana Province, Madagascar
Cabinet, 9.4 x 8.2 x 4.5 cm
A SUPERB, AESTHETIC and RARE specimen of highly lustrous, pearlescent stilbites on beautifully contrasting, black basalt matrix from the same Madagascar locality, that produced the small lot of very gemmy, twinned, colorless to amber calcites a few years ago at the Munich Show. This is a gorgeous specimen, with all of the major and secondary stilbites being pristine. Stilbite is essentially UNKNOWN from this basalt road-metal quarry.
