Cabinet, 10.7 x 5.7 x 4.6 cm
An attractive and interesting combination of various Sturmanite crystal forms. The string of bright lemon-yellow crystals along the center of the specimen are of a more rectangular prismatic habit, and range from gemmy to translucent. The largest is about .9 cm. Some of the outlying crystals are blocky, hexagonal orange-yellow prisms (up to about .7 cm) with very sharp, gemmy, and lustrous pyramidal terminations. The lower half of the specimen is populated by bright yellow, gemmy mm-size Sturmanites. Ex. Charlie Key stock.
