Sahatany Valley, Sahatany Pegmatite Field, Vakinankaratra Region, Antananarivo Prov., Madagascar
A gemmy and terminated multicolored tourmaline crystal in a quartz matrix. This one displays particularly well with even slight back lighting, as the translucent quartz matrix allows the entire specimen to light up.
Collectors tend to prefer matrix specimens, though in Madagascar matrix tourmaline specimens are somewhat harder to find-- many of the most notable specimen producing localities consist of decomposed pegmatites, meaning that any matrxes are usually rather crumbly. Primitive mining methods also make pieces particularly susceptible to damage during extraction.
This crystal was recovered on a solid quartz matrix however, making for a beautifully balanced and colorful example of Malagasy tourmaline.
