Two Columbite blades are partly embedded in the aquamarine base of this large thumbnail specimen. These crystals have dimensions of 0.4 x 0.3 x 0.1" (1.1 x 0.8 x 0.1 cm) and 0.3 x 0.2 x 0.1" (7 x 5 x 1 mm), and both are in excellent condition, showing no fresh damage. Their orthorhombic bladed form is quite good, and each one has a brown-black coloration and a greasy-to-pearly luster. They are accompanied by several small albite blades that are also embedded in the aquamarine base. This base has a few partial crystal faces and shows no fresh damage- even its broken areas have undergone partial healing. It is cloudy but has a beautiful pale blue color.
