At least 30 intergrown Thenardite blades are clustered together to form this hand specimen. These blades reach dimensions of 1.3 x 1.0 x 0.4" (3.2 x 2.6 x 1.0 cm) and are generally in excellent condition, showing almost no damage. Their orthorhombic form is very good, given their intergrowth. All have a dark gray color and a pearly-to-waxy luster, and are translucent to dimly transparent along their edges. There is no host rock present.
