Tourmaline is RARE from Taquaral, Minas Gerais, Brazil, but to find a gemmy and lustrous, 2.1 cm, watermelon tourmaline jauntily set in childrenite-dusted quartz crystals is EXCEPTIONAL! The blue-green indicolite tourmaline with the pink core is beautiful, in itself. The combination with the childrenite on quartz is indeed, remarkable. The gemminess and glassiness of the tourmaline against the childrenite made photography difficult and washed out the pink interior of the tourmaline.
