This specimen features rare gem clusters to 8 mm across, of glassy and gemmy, aquamarine-colored willemite crystals arranged in ball-shaped aggregates. These spheres almost appear to be faceted. Just lovely! Many collectors consider these gem blue willemites to be among best of species in style, although they are somewhat unusual.
