Small Cabinet, 5.3 x 2.7 x 1.7 cm
A very aesthetic example of a mineral that is very difficult to find in pretty matrix specimens. There is a complete 2-cm crystal here, not just opaque but slightly TRANSLUCENT, intergrown with a second crystal that is also complete but grew against matrix on its side. DEEP, GLOWING BLUE color when backlit! Pics here shown without backlighting, though. The crystals stand up very nicely off the matrix. 5.3 x 2.7 x 1.7 cm
