Locality: Pestsovye Keivy, Keivy Mountains, Kola Peninsula, Murmanskaja Oblast', Northern Region, Russia
An aesthetic and showy specimen of sharp, lustrous brown cruciform-twinned and V-twinned staurolite crystals on sparkly muscovite schist from the Kola Peninsula of Russia. An excellent piece with two different crystal habits. You RARELY see both stereotypical crysatl forms for the species in close proximity on the same specimen - this is truly exceptional, even if color-challanged I admit. 5.7 x 5.3 x 2.1 cm
