From the private collection of Mike & Chris Whittier of Rocks in a Hard Place.

Aquamarine (Be3Al2Si6O18), the long bluish crystals, Tourmaline, or Schorl (formula complicated and variable) are the dark crystals, and Quartz (SiO2), the pale smokey crystals, make up this attractive specimen from Erongo, Namibia.
