A single, twinned Spinel crystal is partly embedded in the pegmatite matrix of this hand specimen. It has visible dimensions of 0.5 x 0.4 x 0.2" (1.3 x 0.9 x 0.6 cm) and is in very good condition, showing little damage. Its octahedral form has been twinned according to the Spinel Law, and though its form is otherwise slightly warped, the twinning is obvious. The crystal has a deep violet coloration and a slightly dull vitreous luster, and is dimly translucent. The surrounding pegmatite is loaded with small flecks of muscovite and probably biotite.
